I'd say look at the total=20 memory usage you have now (ram + swap), figure your growth in and scale=20 accordingly leaving extra ram on top of that. You should avoid swapping at= =20 all costs. The dual CPU is good, get the most you can afford there. Your main=20 bottleneck will be the disks - I recommend you actually run more than 2, if= =20 you can get a high performance RAID controller and several disks running=20 the load will be split across the spindles and you'll see a major=20 performance gain, plus data security. With 1 million users I assume you=20 can afford this. If you're load balancing you need to figure out how to replicate the data=20 across servers. That introduces a lot of complexity into the equation,=20 since I'm sure there are multiple ways to accomplish what you need but=20 finding the best one for your scenario and budget could be tricky... -rf At 04:17 PM 11/4/2002 -0600, you wrote: >Hi all > >i have almost 1 million users and i am using qmail with vpopmail >right now i have a compaq proliant 2 procesors p III and 1GB ram >users have 2MB Quota but the servers is geting slow, and i am using almost >all my swap partition (85%) what hardware do you recomend for this server >and how can i balance the load on the server > >I am thinking on a dual xeon DELL poweredge 6600 with 6GB ram and two 73Gb >SCSI > >Thanks > > >----------------------------------------- >"UNIXMEXICO la comunidad *nix en todo M=E9xico!" >http://www.unixmexico.org/ > > > >To Unsubscribe: send mail to majordomo@FreeBSD.org >with "unsubscribe freebsd-isp" in the body of the message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
