According to this page and confirmed by Tim Sneath, only 32-bit IE9 has Chakra JIT engine which explains why 32-bit IE9 performs better than 64-bit IE9. I guess even Flash going 64-bit in beta, 64-bit IE is still not a viable option if it comes with a slower JS engine. :(

According to this page and confirmed by Tim Sneath, only 32-bit IE9 has Chakra JIT engine which explains why 32-bit IE9 performs better than 64-bit IE9. I guess even Flash going 64-bit in beta, 64-bit IE is still not a viable option if it comes with a slower JS engine. :(

It does have the Chakra JIT engine but the 32-bit is very optimized. If read the first few line of the article it does says that.

Edit: I was wrong 64-bit doesn't have any JIT engine at all. 64-Bit IE FAQ

Seems odd to cripple 64bit. At the same time, 32 bit browsers work fine. Do other platforms (OSX and Linux) even show an improvement by moving to 64bit? Math or memory usage? Browsers are certainly becoming more and more important, if 64bit helps, then well, this is a big mistake.

No major vendor has 64-bit final browser as all are currently betas except for Safari and IE.

This is correct. Internet Explorer 9 64-bit does not have Chakra.

Microsoft should focus his energy in 64bit only, let make it like Apple that force everybody to upgrade. If Microsoft continues supporting legacy 32bit processors, part of their customers never going to upgrade.

Microsoft is supporting the 64bit IE. When you install IE on 64-bit Vista or Windows 7. Both 64-bit and 32-bit versions get installed. They have chosen to make 32-bit default because of add-ons. You can force IE to run in 64-bit mode but you will loose some add-on support. IE9 in 64-bit is 8 times faster than IE8.

Currently there aren't many add-ons that support 64-bit browsers. Flash is an example. (Flash-64 has been in beta since last year)

According to Microsoft :

?The 64-bit IE 9 RC doesn?t use the Chakra JIT does it? It uses the older, far less efficient one, right?? Sneath replied, ?That?s correct?we put all our JIT compiler investment in this release of Chakra into the 32-bit compiler, since that?s the one that is near-universally used today. The 32-bit browser is the default even on 64-bit systems, since almost all add-ons are 32-bit only at this time. The 64-bit version provides no real advantage, since no browser scenario requires access to >2GB of user memory in a single process.?

@ SANKE1 typical commnet, have you even fired up IE 9 X64? it is stupid fast, for me 90% of the sites work fine on it, but flash which is important doesn't.

Typical reply. Do you judge persons from their display pic alone? I am using X64 and this news was a shcocker.

:dontgetit: If you've been using the 64bit version of IE and you didn't notice the difference then it isn't too big an issue.

zing!

Honestly you can run 32bit version of IE9 on 64bit win7 without any issue and since this hasn't come up till now (IE9 ahs been in dev for 12 months!) it seems no one saw much of a difference to complain.

Either way it's been hinted that the IE team will jump right back into dev the next version of IE at MiX next month, that version will probably see the 64bit side get most of the work. I agree with them though, in what crazy situation would you need >2GB for a browser process?

They should at least make it more prominent. Many users who don't know this are likely to use 64-bit IE9 thinking now 64-bit Flash is almost here (still not release version), there aren't any issues with 64-bit IE9 and then they would really be experiencing poor JavaScript performance.

Look at who made the first post. Judging by the amount of ranting he's done on Windows 7 and IE9...I'm pretty sure he won't be using any of them.

Although I don't use IE9 all that often, this is pretty poor from Microsoft

Why? Which other browser maker has a 64-bit browser?

Chrome? Nope (not on Windows anyways)

Opera? Nope

Safari? Not on Windows (Mac may be 64bit but not sure)

Firefox 4? Yes

I would rather they get the 32bit version (that 99.99% of people use) working and released and then work on the 64bit. Don't get me wrong I much prefer 64bit over 32 but the world isn't going to switch overnight.

And it's not going to switch any sooner if lazy coders purposely neuter their products because they can't be bothered to work on the development. The simple answer is either provide it, or don't provide it at all. Never do an half-assed job.

And like GP007 has pointed out, if the impact was so big I'm sure this would have been brought up before. But it hasn't. And like he also pointed out they might be working on the 64bit version later on.

    • Anthropic introduces Claude Tag, a new AI teammate for Slack by Fiza Ali Anthropic has announced Claude Tag, a new feature that lets teams work with Claude directly inside Slack. The idea is simple: once Claude is added to a Slack workspace and given access to selected channels, users can tag @Claude in conversations and assign tasks. Claude can then work through those requests using connected tools and data sources before posting its results back into a Slack thread. What makes Claude Tag different from a typical chatbot is that it's designed to operate as a shared assistant for an entire team rather than a single user. Everyone in a channel interacts with the same Claude instance. This allows the team members to see ongoing work and continue tasks started by others. Furthermore, Anthropic says the AI can build context over time by following conversations in channels where it has permission to operate. This means users don't have to repeatedly provide the same background information for every request. The system is also designed for asynchronous work. Instead of waiting for responses in a chat window, users can assign a task to Claude and return later once the work is complete. Anthropic says Claude can break larger requests into multiple steps and use connected tools to complete them. Moreover, the system can also schedule follow-up tasks and continue working on projects over extended periods. Another feature allows Claude to keep the users updated and follow up on unresolved tasks when its optional "ambient" mode is enabled. The company says the tool is already being used internally for software development, data analysis, support workflows, and debugging. According to Anthropic, around 65% of its product team's code is now generated through its internal version of Claude Tag. For organisations concerned about security, administrators can control which channels, tools, and data sources Claude can access. Separate Claude instances can also be configured for different departments, helping keep information isolated between teams. Administrators can also monitor activity logs, review completed tasks, and set spending limits at both the organisation and channel level. Claude Tag is now available in beta for Claude Enterprise and Claude Team customers and runs on Claude Opus 4.8 that was announced this May. The feature will also replace Anthropic's existing Claude in Slack application, with current users able to migrate within a 30-day migration window. Lastly, eligible customers will receive introductory credits to help teams evaluate the new experience.

    • Hands on with the ProtoArc EM25: Affordable ergonomic mouse that focuses on the right things by Taras Buria ProtoArc is known for making all sorts of office products with a big focus on ergonomics and comfort. Its latest product, the EM25, promises a comfortable-to-use, affordable, and customizable mouse. We took one for a spin; here are our impressions. The ProtoArc EM25 is a $49.99 mouse, but right now, during Prime Day 2026, you can get it for just $37.99. Right off the bat, you can see that the EM25 is inspired by Logitech's MX Master lineup and the legendary MX Master 3/3S. Its shape and proportions are very similar, so for a person with large hands (right-handed person, mind you), the EM25 is very comfortable to use. The mouse fills the palm, and the thumb rests on a small extension, giving your wrist a small tilt to reduce strain. The mouse is made of black plastic without any coating, eliminating long-term wear concerns. However, I can see the main buttons and other areas you touch the most getting polished over time. Despite its size and bulk, the mouse is not too heavy. It weighs about 100 grams, which is significantly less than the MX Master 3S and its successor. It is no lightweight gaming mouse by any means, but it is not excessively heavy like the MX Master 4. The EM25 has a built-in storage for its USB dongle. It is a cleverly made magnetic flap that you open by simply pressing on it. Next to the flap, you will find the on/off switch, the 1,000 Hz sensor, and a DPI button (up to 8,000 DPI). I find the DPI button location a bit odd, and I would prefer it somewhere below the main scroll wheel. Still, given that I never change DPI on my mice, I will let it pass. What is more important is that, unlike MX Master 3/3S/4, the device switch button is located below the left-click button, which allows you to switch devices without lifting and flipping the mouse. For a multi-device setup, this is a perfect solution: the button does not require too much effort to use, it does not get in your way, but it is also easily reachable with your thumb. The main scroll wheel has two modes: ratcheted and free-flow. You can only change between them with a bright orange button (I like this little touch of color), which is sprung and requires some effort to press. The wheel is dead-silent in free-flow mode, but ratched is quite loud and stiff, perhaps even too much to my liking. I can hardly call it deal-breaking, but it will certainly take some time to get used to. The side scroll wheel, it is notched, silent, and pleasant to use. Next to it, you can find a piece of glossed plastic with connection indicators: Dongle, Bluetooth 1, Bluetooth 2, and the low battery indicator. By the way, the built-in battery is rechargeable via a USB Type-C cable, which is included. It is sleeved and has an orange velcro strap to keep it tidy. After using the EM25 for a few weeks, I can say that its main buttons are my absolute favorite. They have very pronounced clicks, which feel great with just the right amount of force required to register a press. I would say they feel like something in between regular mouse clicks and silent ones. You can hear and feel the springy switch, but it is not sharp or loud to the point of annoying you. As for back/forward and device switch buttons, they are very clicky and quite noisy. Unfortunately, there are no extra buttons that you can map to specific things like in the MX Master lineup. Besides great primary clicks, another thing I like about the EM25 is its 1,000 Hz sensor. In the world, where Logitech still uses 125 Hz sensors in $100+ mice, seeing a much faster sensor in a mouse that costs three times less is very refreshing. Also, all the settings and customization you make are stored on-device, and you do not need to install any software. Just open the web-based app and change all that you need. Speaking of customization, you can remap what buttons do, adjust the DPI, and the sensor speed. Sadly, gestures are not supported, but you can still map pretty much anything to each button, including shortcuts, media buttons, and more. I also recommend using software like XMouseControl, as it will let you remap the side scroll wheel. At the end of the day, the ProtoArc EM25 is a great mouse. Clearly inspired by the MX Master lineup, it takes the best of it and complements it with a much more wallet-friendly price tag, significantly better sensor, on-device memory, a built-in storage for the dongle, and more (it fixes everything that I complained about the MX Master 4 recently). And for only $37.99 during Prime Day, the EM25 is an easy recommendation. Buy ProtoArc EM25 mouse - $37.99 | 24% off with Prime As an Amazon Associate, we earn from qualifying purchases.
