Server consuming 100% CPU after upgrading to dual cpu

After upgrading from one to two CPU's the server is consuming 100% CPU. My website has become incredibly slow after the upgrade.

The CPU's are identical except for the L2 cache. The newest CPU has 8MB while his older brother has 4MB.
Could this be causing both CPU's to run slower?

Apart from adding the CPU I did nothing else.
 
Thanks for your suggestion, but I think that is not it:

grep -i cpu /var/run/dmesg.boot gives me:

CPU: Intel(R) Xeon(R) CPU E5310 @ 1.60GHz (1595.94-MHz K8-class CPU)
FreeBSD/SMP: Multiprocessor System Detected: 8 CPUs
cpu0 (BSP): APIC ID: 0
cpu1 (AP): APIC ID: 1
cpu2 (AP): APIC ID: 2
cpu3 (AP): APIC ID: 3
cpu4 (AP): APIC ID: 4
cpu5 (AP): APIC ID: 5
cpu6 (AP): APIC ID: 6
cpu7 (AP): APIC ID: 7

So that seems to be in order. Still I have doubts about the different cache size.
 
Are you sure you can use different CPUs.
Perhaps check the manual of the motherboard, I'm sure
they will recommend two exactly identical CPUs.
Those two CPUS you mentioned might have other differences
except for the amount of cache available.
