I changed from using HP DL380's to Dell 2950's in the last year or so since it has better support for OpenBSD. With the DL380's, we were getting about 70,000 pps during tests but after following the explanations about network performance tuning in a great article by Henning Brauer (I have been searching for it for the past hour but can't find the URL -- it was at the www.openbsd.org web site and I had downloaded it couple of years ago), we could get 180,000 pps on DL380's. On the 2950's, I haven't done any tests yet but as soon as I find that paper, I will do so. -- Vijay Sankar, M.Eng., P.Eng.
