Mongrel CPU Usage

Hi
Just wondering whats reasonable to expect in terms of mongrels CPU
usage. I've established an app with 1 mongrel instance on a debian
etch box. This process idles (yes idles) on 10% - 20% - this means say
I install 10 apps each with 2 mongrels, I've used twice my cpu
capacity _without_ even accepting a hit!

is this reasonable/typical behvaviour from mongrel? What are the
minimum specs of a cpu people are typically using for mongrel?

heres my /proc/cpuinfo:
processor : 0
vendor_id : AuthenticAMD
cpu family : 6
model : 10
model name : AMD Athlon(tm)
stepping : 0
cpu MHz : 1250.065
cache size : 512 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge
mca cmov pat pse36 mmx fxsr sse syscall mmxext 3dnowext 3dnow up ts
bogomips : 2506.90

Thanks for any hints

IM(very limited)E, I'd say something is definitely fubar with your config. I'm on a VPS at a2hosting with 10-12 other apps on the box and, looking at top, your numbers are way out of whack.

There's a new, better place to post your question. Robby Russell from PlanetArgon started it for just this kind of thing and all the top-level Rails admin talent is there. http://groups.google.com/group/rubyonrails-deployment?hl=en

They're here too, of course. It's just a signal/noise thing.

hth,
Bill

great that -will follow that up
thanks

No way. CPU usage should be negligible when not processing requests.
Are you sure you're not accidentally reading the value from the memory
usage column?
