0 +BudMan MVC Posted April 10, 2012 MVC Share Posted April 10, 2012 not sure what you mean by 7zip in a file transfer? You man while compressing something over the wire? As to Teracopy -- why would you use it? I have tested it since has come out, and not once have I seen it be a faster copy.. Be it disk to disk, over the wire, etc.. Never seen it copy faster no matter what settings I have done with it. 55-75 is pretty screaming if you ask me.. Why would you care what teracopy crapware does?

0 UseLess Posted April 10, 2012 Author Share Posted April 10, 2012 Yeah, I mean extracting something from an archive stored on another computer on the network. What underlying mechanism it uses to pull files over the network, suffers from the same issue Teracopy does. I started using Teracopy awhile back - WinXP - and it decimated the WinXP file transfer handler. Flexible buffer size, skipping files, etc all mashed XP into the ground. Offered more features, and was significantly faster in some cases. I haven't noticed any speed difference on Win7, I'm pretty sure MS improved their handler leaps and bounds during Vista =) With regard to why I use it, its mostly for its 'drive sense'. I have all my data on drives stored as JBOD, and if i start 10 transfers, Teracopy will run one transfer at at time, rather than run all 10 at once and bottom out the hard drive. If they are on separate drives, Teracopy will copy two things at the same time. I also like being able to see what files it has already transferred. So no, Terracopy is not as essential as it used to be on WinXP, but (other than this speed issue) its FAR from crapware. So yeah, thanks for the reply budman, but other than bashing a perfectly useful piece of software...not helpful. Link to comment Share on other sites More sharing options...
0 watchthisspace Posted April 10, 2012 Share Posted April 10, 2012 Yeah, I mean extracting something from an archive stored on another computer on the network. What underlying mechanism it uses to pull files over the network, suffers from the same issue Teracopy does. Unzipping an archive will be slower because the CPU has to unpack the contents of the archive, then use an algorithm to create the unpacked file/files, place what's unpacked into a tmp folder until its complete, then move it to the location you want. Teracopy is a perfectly fine file transfer program for the reasons you mentioned, much better for multiple file transfers. I'm not sure why it's copying so slowly, maybe it's creating too many connections and flooding the network. Link to comment Share on other sites More sharing options...
0 +BudMan MVC Posted April 10, 2012 MVC Share Posted April 10, 2012 Sorry but I have tested that software since XP -- even with XP it never did faster anything... Not saying it does not have some useful file copy features, but its claim to fame is that your speeds will be faster -- which every single test I have with that software has not once shown this. Multiple computers - never even 1mbps faster.. Sorry if you make **** up about about your product - its CRAP! As to your extraction issue -- what are you extracting so I can try and duplicate. is it lots of tiny files in a 7z, or large file compressed? I just did a simple test of lots of pics in a zip file that I extracted with 7z and not seeing any 20mbps limit. As to moving large amounts of files - I have always just used robocopy from the cmd line -- as to feature set, blows teracopy away that is for damn sure. And guess what it never claimed to make your copies faster ;) So it don't make bold face lies! BTW.. was reading a thread about the new N40L that I just setup as to file speeds and came across this little tool for testing. NAS performance tester 1.4 http://www.808.dk/?nastester Running warmup... Running a 400MB file write on drive Y: 5 times... Iteration 1: 46.94 MB/sec Iteration 2: 79.36 MB/sec Iteration 3: 75.94 MB/sec Iteration 4: 61.99 MB/sec Iteration 5: 64.91 MB/sec ------------------------------ Average (W): 65.83 MB/sec ------------------------------ Running a 400MB file read on drive Y: 5 times... Iteration 1: 85.30 MB/sec Iteration 2: 87.50 MB/sec Iteration 3: 87.33 MB/sec Iteration 4: 85.27 MB/sec Iteration 5: 90.33 MB/sec ------------------------------ Average ®: 87.15 MB/sec ------------------------------ These are the speeds I am getting over my gig network to and from a VM, and that 7z test I did was from a drive shared off a VM running on esxi 5u1 off a little $270 N40L box.. You sure don't need expensive hardware these days to get decent network speeds. Link to comment Share on other sites More sharing options...
0 UseLess Posted April 10, 2012 Author Share Posted April 10, 2012 @watchthisspace: brilliant idea! Checking out the performance monitor while extracting! @budman: yeah their speed claim WAS right, but isnt anymore =P you're right on that one. Aww haha way to rub it in, your 7zip loves you more! Huzzah, you're all brilliant! =) Not sure why, but your screenie made me think of admin rights. Run as admin = full speed! Guess UAC doesn't play nice with Win7 on my machine. Any ideas why running without admin rights would restrict speed? Link to comment Share on other sites More sharing options...
0 +BudMan MVC Posted April 10, 2012 MVC Share Posted April 10, 2012 Screenie admin rights? I have UAC enabled that is for damn sure. Yes my account is in the admin group, but UAC is default settings. I can drop into a standard account to test, but that should have nothing to do with copy speeds, or extract speeds. Link to comment Share on other sites More sharing options...
0 UseLess Posted April 10, 2012 Author Share Posted April 10, 2012 Yeah I'm the same. Running with UAC, on an admin account. If i "run as admin" my 7z goes full speed, however if i just open it with restricted privileges then it caps out at 20mbps. Link to comment Share on other sites More sharing options...
0 +BudMan MVC Posted April 10, 2012 MVC Share Posted April 10, 2012 I did not elevate mine when I ran it.. Hmmm very strange. Have you tried different compressions, mine was just some zip file not 7z, etc. What algorithm is your archive file -- trying to duplicate issue.

Question
UseLess
I have recently upgraded to an unmanaged gigabit switch (cos gigabit is cooler than FE) and am testing out transfer speeds.
When using the standard windows file transfer method, I get about 55-75mb/s - I'm happy with that.
When using Teracopy or 7Zip it caps out at 20mb/s - doesn't fluctuate, just caps out, as if the connection is limited.
I'm stumped myself. Anyone got any ideas? Run into this before?
