Server: Win2003 Standard SP1 - 2.5GHz, 1GB Ram

I am noticing that after about 500 total user connections over a 3 day period that authentication, listing, and changing directories starts to crawl. File transfers remain fast.

I restart the FileZilla service and everything is flying again.

The server was still using minimal amounts of ram and virtual memory but it behaves as if there is a memory leak. I think I will just schedule a nightly service restart for now.

I have searched the board and there are many posts about slowness but I did not find any that talked about slowness after moderate to heavy usage.

Any insight or workarounds would be appreciated. Thanks!

You might try testing on a different server platform, just to rule out any possible memory leaks from other applications on the current server platform.

I think I can confirm this. We have a fairly busy ftp server, and after it has been on for a week or so, I start getting calls about it being very sluggish for login/directory listing etc. Also when it is being affected by this sluggishness, I get occasional "425" errors but the rest of the time passive mode works fine, as does every other aspect of the server most of the time.

Restarting the service fixes it for a few days, as rwilliams has said.

My server is running on Windows Server 2000 with all the latest service packs etc. Another thing I should note is that I'm using port 1121 instead of 21, and my custom port range for passive is 1130-1250
Just to be safe, I've forwarded ports 1110-1250 to the server machine.
