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, as well as Proftpd and they both exhibit 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? Is anyone else seeing this? -- Bill Moran Potential Technologies http://www.potentialtech.com
