I'm serving several Windows 2000 clients from several FreeBSD 4.3 servers and I'm running into a performance bottleneck somewhere which appears to be on the Windows 2000 side of things. Performance w/ FreeBSD -> FreeBSD is great! Hardware: * Intel 2x1 Ghz CPUs * 1 gig of RAM * Extreme Summit 1i w/ Copper and SX Interfaces Performance w/ ttcp (for UNIX + Win32): FreeBSD 4.3 + Netgear 622T -> FreeBSD 4.3 + Netgear 622T = 875 Mbps FreeBSD 4.3 + Netgear 622T -> Windows 2000 + Netgear 622T = 350 Mbps FreeBSD 4.3 + Netgear 622T -> Windows 2000 + 3Com 3c985-SX = 350 Mbps I've tried running multiple instances (overlapping) of ttcp w/ no performance increases (ie: each instance halfs thruput) and I've tried tweaking the following on FreeBSD with no results: sysctl -w net.inet.tcp.delayed_ack=0 sysctl -w net.inet.tcp.sendspace=65535 sysctl -w net.inet.tcp.recvspace=65535 Does anyone have any opinions on how to tweak the performance on either end?
