Sudden drop in utorrent download speed


Question

Hello,

I've just started using utorrent on my laptop today and originally I could only reach 30 KB/s max. I configured the setting in preference and was able to get it up to around 300 KB/s.

The problem is that it only stays at this speed for 1 min max and then falls around the 30 KB/s ish area again. Occasionally it will climb back up too 300 KB/s again before dropping back down again

Can anyone help

A few things to do.

  1. Set your upload limit to about half of your maximum upload speed to prevent the upload clogging up the download overhead.
  2. Enable encryption on the BitTorrent tab. To be really sure you could set it to Forced, and uncheck the 'legacy connections'.
  3. If the torrent consists of multiple files your speeds could drop when ?Torrent is reserving file space. When the speeds drop, check the status bar for Disk Overload. If it says Disk Overload your speed drop is perfectly fine. After the first few percent of your download you probably won't see any more Disk Overloads.

In general ?Torrent works perfectly fine. Speed drops happen from time to time at the start, but it'll stable out after a few minutes max.

Thanks. Some of the thing you suggested i had already done but I tried the one about upload speed and it's seemed to level out.

What's the best port to use?

Anything really, just hit random port and make sure the port check works out. Make sure UPnP is enabled both in ?Torrent and on your router's config page. But it doesn't even matter that much for speed, good port forwarding just helps you getting connections faster.

You don't need UPnP -- this is for people that do not understand what a port is, or how to forward it through their routers.. Its for grandma to be able to have unsolicited inbound traffic get to her machine ;)

Are you wireless? Wireless and torrents not really a good fit!

300KB is pretty slow download.. What are you internet speeds -- quick test from speedtest.net should give us something close. Just make sure you not in the middle of doing torrents when you test.

300KB is like 2.5Mbps -- sounds like a wireless G connection to me.

edit: If you on a wired decent speed internet connection. These are more common speeds you should be seeing

And i am in the middle of uploading 1.5 GB of stuff to my dropbox as well. Unless your on a really bad internet connection, or wireless 300KB is really slow for a decent seeded torrent.

Oh right thanks for that!

Yes I am wireless. It's a BT home hub 2. I don't think my Internet download speed is too great (around 2.5 like you said). I'm not sure if it's that low from my dad being a tight arse and not paying for a good package or BT ripping us off!

Well you never going to see your true internet speed wireless, unless its less than your wireless speeds.

Connect your box to the router with a ethernet cable and then test your internet connection.

Doing torrents over wireless kills WIRELESS!! for anyone one else on wireless.

"I get my 6.8MB/s (yes Byte, not Bits)"

And your not on G wireless are you ;)

And I get

[ ID] Interval Transfer Bandwidth

[156] 0.0-10.0 sec 978 MBytes 97.8 MBytes/sec

Over my gig connection -- so what is your point?

Wireless is SHARED bandwidth -- does not what portion you try and choke up or down. Its not duplex and its shared.

    • This Chinese company is reportedly developing a feature Apple and Samsung can only dream of by Hamid Ganji While companies like Apple and Samsung have been relatively conservative with their devices’ battery capacities in recent years, Chinese manufacturers have taken the competition to the next level by introducing significantly larger batteries. However, the latest report from China suggests that a local company may already be developing a smartphone with a whopping 14,000mAh battery. Chinese leaker Digital Chat Station claimed on Weibo that a smartphone maker is developing a device with a 14,000mAh battery. If true, it would be the largest battery ever used in a smartphone and could, in theory, provide up to a week of battery life on a single charge. The leaker did not reveal the name of the company behind the device, but there are some clues. This week, HONOR unveiled the X80 Pro Max in China with an 11,000mAh battery and 90W wired charging support. The company also launched the Honor Win in January, which packs a 10,000mAh battery. HONOR, a former subsidiary of Huawei, has a proven track record of developing smartphones with unusually large batteries. However, other Chinese brands, including Xiaomi, have also launched devices such as the Xiaomi 17 Pro Max with 7,500mAh batteries. Though Chinese users on Weibo also believe the company behind the new battery is HONOR. Interestingly, Digital Chat Station said the device with the 14,000mAh battery weighs around 220 grams, making it lighter than the Apple iPhone 17 Pro Max (233 grams) and slightly heavier than the Samsung Galaxy S26 Ultra (214 grams). The iPhone 17 Pro Max currently packs a 5,088mAh battery in eSIM-only versions, while the Galaxy S26 Ultra features a 5,000mAh battery. Neither device is expected to see a dramatic increase in battery capacity in its next-generation successor. So when it comes to battery comparison, Chinese brands are unbeaten. HONOR smartphones are currently available in the EU, but the Chinese brand has no official presence in the United States due to restrictions imposed by the U.S. government.
    • Qualcomm takes on NVIDIA with new Dragonfly CPU and AI chips by Pradeep Viswanathan Microsoft, Google, Amazon, AMD, Meta, Apple, OpenAI, and several others have been developing their own chips for AI infrastructure. However, NVIDIA still remains the dominant player in the market. Today, Qualcomm announced a major expansion of its data center infrastructure portfolio to better compete with NVIDIA. The new lineup includes the Qualcomm Dragonfly C1000 CPU, Qualcomm High Bandwidth Compute technology, the Dragonfly AI300 inference accelerator, new connectivity products, and custom silicon solutions. Qualcomm claims that this new lineup improves performance per watt, token throughput, and total cost of ownership for AI data centers. The Dragonfly C1000 is a new data center CPU built with Qualcomm’s custom Oryon cores. This chip will feature more than 250 cores, frequencies above 5GHz, and a chiplet-based design. Qualcomm claims that this new C1000 can deliver more than 2x better performance per watt compared to existing server CPU offerings based on specifications. The Dragonfly C1000 will support PCIe Gen 7 with more than 2TB/s of connectivity, along with CXL, advanced RAS features, and both air and liquid cooling. Qualcomm expects the Dragonfly C1000 to be commercially available in 2028. Additionally, Qualcomm and Meta announced a multi-year, multi-generation agreement under which Qualcomm will supply Dragonfly C1000 data center CPUs for Meta’s next-generation server fleet. Qualcomm also announced High Bandwidth Compute, a new near-memory computing architecture designed to address AI’s memory bandwidth bottleneck. HBC Gen 1 will debut with the Dragonfly AI250, which is expected to sample in mid-2027. The AI250 will deliver 133TB/s per card, an 18x increase in effective memory bandwidth compared to the AI200 with LPDDR5X. The new Dragonfly AI300 with HBC Gen 2 is a rack-level AI inference platform from Qualcomm. Qualcomm claims that the AI300 can deliver 4x to 8x better performance per watt compared to existing GPU-based architectures based on memory bandwidth per watt per card. The Dragonfly AI300 is expected to be available in 2028.
