It did, and now uploads work correctly, and fairly quickly!

Transferred 59.247 MB

put took 13.765 seconds = 4.304 MB/sec

ContextSwitches - 75051

First level fills = 0

Second level fills = 0

ETime( 0:00:14.124 ) UTime( 0:00:02.203 ) KTime( 0:00:00.890 )

ITime( 0:00:12.218 )

Not as fast as most other clients, but much closer than before.

I checked the file on the destination with md5sum and it arrived OK.

I tried one test with a get and it was faster:

Transferred 59.247 MB

get took 9.641 seconds = 6.145 MB/sec

but I haven't tried with over a network with delays.

If I remember correctly, the multiple-packets-pending optimization

hasn't yet been applied to downloads.

In the next few days, I'm gonna try downloads over the Internet,

plus test on Linux and maybe even Solaris instead of Windows.

Thanks!

Mark
