high speed timestamp counter
Title: high speed timestamp counter Hi there, I am trying to read the on board Pentium Time Stamp Counter. Is there an API in Unix that allows me to read it directly? Or some assembly language line that I can drop into my code? I need the high speed counters to profile some code. I don't want to use the classical time API that is provided in -Hao

RE: need a recommendation of NIC
Title: RE: need a recommendation of NIC Thanks for your info. I'm using FreeBSD v3.3 which suppports The PRO/100B with chipset 82558.

I've been using Pro/100 cards for years, and I've always found them rock stable.

need a recommendation of NIC
Title: need a recommendation of NIC I am doing some testing on FreeBSD 3.3 platform by sending some UDP packets thru FreeBSD routers. It's found that the duplications happened in FreeBSD router. Now The FreeBSD 3.3 is running on Pentium III, and NIC is 3C905B-Tx. To isolate this problem. We will try different NIC. Can anyone give me some recommendation for the high performance NIC for FreeBSD 3.3. Thanks in advance for any comments. -Hao
