Can't upload large files

[neo_bahamut]

Version: 3.0.2.1
OS: Windows XP (standard precompiled build)

I can't seem to upload anything above ~100KB. I thought this was a problem with the hosting service (bandwidth limit was reached), but I have the same issue with Sourceforge, and FileZilla 2.2.32 doesn't have this issue with either site. When I try to upload a large file, the progress bar will shoot to ~100KB finished (and I'm using dialup, so there's no way I can get 100Kb in less than a second) and stop. It will act like it's uploading, and after ~10 seconds, I get time out errors and (usually) a lost connection. After another few seconds it will ask me what to do (overwrite/resume/skip/etc.) even if the file didn't exist previously. I guess it uploads a little of the file and tries to upload again. In this example, I had it try to overwrite, and the cycle repeated. Then I had it resume, and the same thing happened. This example is with digital-signal.net (FTPES), but the exact same thing happens with Sourceforge (FTP). I can do the same thing and provide a log with Sourceforge if you want. I've also included a log from 2.2.32 with an attempt to upload the same file from the same place to the same place. The upload was successful with 2.2.32.

Try increasing the timeout value to about double the time it usually takes to transfer 100KB. The headstart is caused by the internal socket buffer of Windows.

I changed the timeout to 45 seconds, and could then transfer a large file, however, the progress bar is not smooth. It "jumps" instead of being smooth. Is there any way to have smooth progress bar updates (like I do with 2.2.32)?

In the next version of FileZilla you will be able to manually adjust the "Socket recv buffer size" and "Socket send buffer size" in the settings file.
