server sizing for haproxy

Hi All,

I've been using haproxy for a while (v1.2.16) and I'm noticing that my CPU usage for the haproxy process is around 70% during normal load with occasional spikes to nearly 100%. We're running on a basic desktop class PC right now with 1 Intel(R) Celeron(R) CPU 2.53GHz CPU and 768MB.

We're at roughly 2000 concurrent connections right now and about 20Mb of bandwidth at peak.

Is our hardware definately too small at this point or could something else be wrong?
Would upgrading to haproxy 1.3 help or hurt us? If you do think we're undersized on the hardware, any suggestions as to how much we'd need to 5-10x where we are now?

Thanks!
