Hi,

There was an e1000g issue that may affect the throughput on opensolaris 2009.06 (snv111b), which was fixed in snv125. To verify if it's related, could you please add
lso_enable=0,0,0,0,0,0,0,0;
in /kernel/drv/e1000g.conf. Then you can reload the e1000g driver or simply reboot the system.

Thanks,

Miles

Hi I have some slow network issues when transferring from one opensolaris box 
to another (using NFS and Samba) and want to check the network (ie. I am 
getting 40MB instead of 90MB+ I would expect) from e1000g0 to e1000g0. The file 
systems at each end are ZFS raidz and raidz2 pools with 200+MB write speeds 
(tested with dd and large files...not the best test but good enough to say it's 
pretty fast).

Is iperf the best thing to use for verifying the base speed and if not, what 
should I use?

I have used iperf before under Ubuntu/windows...but am new to opensolaris and 
do not know how to get it for opensolaris 2009.06.

I can not find any guides...some posts mention compiling it, but I do not know 
how to...are there any step by step guides?
