I have dual L5640 Wesmere processors (dual 6 core = 24 thread) and I get horrible performance no matter which exe I use... or even running via Linux, 100 h/s is about all I get. Is there a bug or something I'm missing?

Try it with 6 threads per cpu, that should better fit the L3 cache and make sure the miner recongnizes AES.
Otherwise I need a lot more info.

Are there any debug logs or anything like that I can retrieve? any parameters I can add, when launching, to get additional debug info ?

You mean like a console session? Why haven't you posted that yet? There's a lot of good info displayed when the miner starts up,
it should be obvious to post that as a minimum when asking a question.

OK got some info - also, the result is no different in v3.4.7

edit: Also a note about config... these results were compiled with march=westmere -O3 ; trying other variations doesn't do much +/- a few percentage points (march=native, -O2,1,fast etc..)

Just a note about this - I was reading about this issue a number of days ago and someone mentioned that AES may not actually be enabled even though it says that it is? I just can't imagine that dual 6-core L5640 processors would perform like this without something being wrong. I tried doling things out via numactl and that didn't have any impact to speak of.

Good data. It appears only 1 CPU is mining (there are 2 right?), it doesn't look like the miner supports multiple CPUs.
Other than that everyting looks fine, you get higher hashrate with 6 cores vs 8.

For cryptonight the optimum thread count is (L3 cache size in MB / 2).

Edit: What's the default thread count, does it represent both CPUs?

It's defaulting to 12 threads so that tells me that it does take multiple CPU's

also of note, I've got this running on numerous dual 16-core opteron setups and it takes those like a champ... 900H/s
