Ive used Fbsd for years, but have never thought much about tuning NFS for maximum thruput. I hope to be using the Alteon Gig-E card(s) in the Fbsd box, this is a P3/550/256Mb system. Questions: 1) Will the box perform better with ONE card doing reads from one box, and the other writing to the destination filer? Or one card doing both. (mainly a question about how will the data work best..across the bus, or within the same card during the Xfer) 2) Specific kernel tricks to enhance data movement. The data set isnt all large files, but a large free WWW hosting site, tons of small files as well as www server logs for thousands of virtual servers. 3) Can anyone reccomend perhaps a better card than the Alteon? We stopped using the Alteon at NetApp because of it's overall dismal performance. The Intel GigE card would be quite nice..if I had a choice.
