[u]Server[/u]: OpenSolaris snv_82 (I upgraded since first post hoping it would help... it didn't) AMD 690v chipset AMD Athlon 64 X2 4000+ 1 GB RAM Onboard Realtek ethernet (Realtek 8101E, rge driver) 4 500GB Seagate SATA 7200.10 in RAID-Z zpool
[u]Clients[/u]: Gentoo workstation, kernel 2.6.23 Windows XP MCE 2005 The network is pretty simple, I have a Net BSD router serving up IPs to these machines, and they're all sitting on the same 10/100 switch. I made two snoop logs, but they're pretty big, so I've included links to gzip'd versions (the attachment thingy wasn't behaving in Safari). My procedure for generating them was as follows: First, I started snoop on the server, redirecting the output to my first snoop log (snoop1.log). On the Linux machine, I mounted the CIFS share, then started a file copy from the share to my local home directory. Speed was about 200 KB/s (a mysterious improvement, but still pathetic). I let the copy run for several seconds, then stopped the snoop. At this point, I started snoop again, this time redirecting output to my second snoop log (snoop2.log). After starting this snoop, I started a second file copy from the share to my local home directory. The first copy was still going when I started the second copy. As soon as I started the second copy, transfer speeds on both copies shot up to about 5 MB/s, saturating my available network bandwidth. I let the second copy finish, and as soon as it had, transfer speed on the first copy dropped to about 200 KB/s. I then stopped snoop. The first log is about 4 KB compressed, 400 KB uncompressed. The second is 70 KB compressed, 9 MB uncompressed. http://www-personal.ksu.edu/~tcm/snoop1.log.gz http://www-personal.ksu.edu/~tcm/snoop2.log.gz I've done a little bit of fiddling with dtrace at work... if someone can give me some pointers, I may be able to spit out some more helpful information. As it is, I wouldn't really know where to start.
