My server has a C2D E8500 and 4GB RAM for 4 concurrent users. It has no trouble keeping up, with teens on facebook, youtube, addictinggames, nexopia, etc. The only real bottleneck I've been able to reproduce is on HD or fullscreen flash videos. The GBE clients are smooth enough, but 100mbit is not enough for that. If you have 10 clients all using flash then you might see a quad-core sputter, but I think not until then. That said, it's important to plan for worst case, and future needs as well. I tend to agree with the Luke in recommending a 6-core CPU with a second socket for upgrading. > - I want to use a SSD for the system and a NAS for homes directory and for > storage space of the proxy. Comments? SSD for system and Windows VM. Sandforce controllers are where it's at right now. My current server has a pair of Intel G2 80GB SSD in RAID0 (software). You lose TRIM in RAID, but that wasn't a concern when I built it, and performance has been great (overkill, even). > - same question with the /tmp partitions. For /tmp I recommend a ramdisk (tmpfs). Give yourself loads of RAM and check out this interesting blog post, which I've used on several installs using several Ubuntu releases. You don't have to go 100% ro, but it's still good for pointing out directories that could unnecessarily bottleneck your IO or cause accelerate the death of your SSD. http://www.staldal.nu/tech/2009/11/15/linux-with-mounted-read-only-2-0/ Have fun with your new build. db ------------------------------------------------------------------------------ Achieve Improved Network Security with IP and DNS Reputation.
