Charles,

Squawk!

Unfortunately, with XP SP2, Cygwin 1.5 as the server machine, I get
pretty much the same symptoms with each of the above ftpds serving up
a 350mb file:

1. In all cases, the ftpd process' memory usage increases to ~350mb,
2. As the buffer value decreases, the process' cpu usage increases
(ftpd-1k.exe used about 75% of the cpu vs. about 10% for ftpd-8k.exe),
3. Performance jumped around (ftpd-1k transferred the file in
90seconds, ftpd-4k in 166 seconds, ftp-8k in 114 seconds on a wired
network)

Sorry!

Ant.
