I'm having some really weird performance problems with proftpd-1.2.10 on FreeBSD 4.10 (in a jail) that I just can't seem to figure out. My uplink here maxes out at about 35k/sec. If I scp to the machine in question I get about 30k/sec (which is expected) but when I ftp, I never get anything better than 15k/sec, and occasionally as low as 8k/sec. Using a server colocated at another facility, I can ftp at about 45k/sec, and scp at about 60k/sec. Downloads are all as expected ... scp and ftp downloads seem to be in about the same range, and it's a number I would expect. I tried running the ftp daemon that ships with FreeBSD, and it exhibited the same performance issues. Most settings on this machine are at their defaults. I've tried tweaking send/recv sizes, as well as toggling delayed_ack. None of these have made any difference so far. Suggestions? -- Bill Moran Potential Technologies http://www.potentialtech.com
