Need more information. Which version/build of solaris are you using? What are the UDP packet sizes? What machine is this (cpu type and speed), etc? Which NIC is this?

Hi,

I need some help with regards to tuning the UDP parameters to improve the
performance. On a 1 Gbps link, I am only able to receive at 350 Mbps, and
send at around 600 Mbps.  I would like to mention that the CPU and disk io
are not the bottlenecks. Should I play around with udp_max_buf,
udp,recv_hiwat, and udp_xmit_hiwat?

Thank you,
Vish
