With the patch above, I was unable to build the test program. You?

Under x86 I had to include cryptopp/obj/cpu.o in the list of object files, otherwise “make test” would fail. Under x86_64 I had no such issue.

The original patch posted is working just fine for me (Opteron 2376), and did double my performance over the stock 0.3.6 client. I was even able to port its minor changes to 0.3.7 successfully, with the same results.

As I said above I did notice an imporvement in performace too, but I am not sure the patched version works correctly. Have you been able to generate any blocks with the patched version?

Yes, since applying this patch I’ve generated 2 blocks.
