Incorrect CPU profile in 22.9 and 22.8

Just noticed that under 22.8 and 22.9 the L1 cache size is misreported on my AMD processors. L1 is reported as 64KB instead of 128KB.

I suppose it could be reporting the data cache instead of the entire cache size. (It would be nice if a breakdown was given, if that is the case. :) )

I guess the real question is whether this affects performance...

It does not affect performance

I just checked the code. It is reporting only the data cache size.

Thanks for checking George. Sorry about making a fuss over a non-issue.
