CPU usage high but no process that´s hogging up, just 0.0% idle

I guess the case is that it´s low cpu just want to make sure that´s the case:)
it´s a p3 933mhz with 512mb ram and running pfsense 1.2
when running torrent with dl ~4-5mB/sec i get this high load avarege and ~0-10&idle
thought 933mhz would be enuf for this but i guess it´s not.
Does that meen it´s the system itself that requires all the system resourses and that i need faster cpu?
here is a snap from "top"
last pid: 8240; load averages: 12.53, 9.27, 5.03 up 15+12:33:52 07:58:25
54 processes: 9 running, 43 sleeping, 2 zombie
CPU states: 1.0% user, 1.0% nice, 4.9% system, 93.1% interrupt, 0.0% idle
Mem: 91M Active, 12M Inact, 58M Wired, 58M Buf, 332M Free
Swap: 1024M Total, 1024M Free
EDIT1: roughly 1500states
CPU usage is so high that i loose connection with ssh(from external place) and regaining access when dl is complete

I would suggest upgrading to 1.2.1. Probably something wrong or nics are generating to much interrupts.
The 93.1% interrupt time suggests your system is overloaded. Interrupt sharing could contribute some of that.

YEs, too much interruption requests. Checks your NICs.
Whats the output from shell command vmstat -i
That will help identify whats contributing to the interrupt load.

As other members say, your cpu hogged by way too many interrupts coming in/out, looks like for every single packet. As far as there's no hardware issues around, then it's time that you definitely need to consider swapping a nic which has polling capability, or enable polling for the device if already have those. I dunno if 1.2 gui allows you configure polling then use shell. Moving to 1.2.1/1.3 is also a good idea.

tnx for the answers
i now have moved to 1.2.1 (nice with vlan working on 1.2.1)
side note, on install i noticed it was a 733mhz and not 933
I was able to dl much faster and the box did´t disconnect me eather
Numbers from "top" was roughly the same..maby a bit lower but twice the speed(9mB/sec) on download
So i guess that it is the cind of performance you can get from the hw i have now.
I second the suggestion you try polling. It will probably help squeeze a bit more out of your machine.
