And then it just gets slower and slower. If it's samba, I have no idea what. I'm running a current samba, pretty much the default config. On large files I see 12-13MB/second. If my switch supported jumbo frames I'm sure it'd be even faster. I'll do some of the tests from the command prompt, see if I see the same thing. On Sat, Apr 10, 2004 at 11:38:35AM -0400, Brian F.
