I've tried pure-ftpd and vsftpd and got very low upload speed (~200kb/s) per a connection. but when I download on the server using wget speed is 2Mb/s

on the ftpclient from which I do upload if to increase the param I/O buffer size till 1Mb upload speed increases to ~2Mb/s

when I use these ftp demons on the Linux server there is no such kind of problem and I do not need to correct I/O buffer size it seems it is identified automatically on Linux.

how should I set up FreeBSD to increase default I/O buffer or identify it automatically for ftp incoming connections.

please advise if you are able.

thanks a lot!
