I can't really say on the load balancing, but for the other stuff: Your system is probably slow because of the swapping - that's a lot of continuous CPU and disk activity to slam it. I'd say look at the total memory usage you have now (ram + swap), figure your growth in and scale accordingly leaving extra ram on top of that. You should avoid swapping at all costs. The dual CPU is good, get the most you can afford there. Your main bottleneck will be the disks - I recommend you actually run more than 2, if you can get a high performance RAID controller and several disks running the load will be split across the spindles and you'll see a major performance gain, plus data security. With 1 million users I assume you can afford this. If you're load balancing you need to figure out how to replicate the data across servers. That introduces a lot of complexity into the equation, since I'm sure there are multiple ways to accomplish what you need but 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 México!" >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
