That is a really good result, but to short to be definitive.

That is a very good result, even for software stepping.

I second tommylight, very good results indeed. There is one thing that I saw lately: randomly, the browser stopped playing videos. Thus load on the pc was low. Thus: Was your browser constantly playing videos? If not sure, repeat the test and check from time to time.

Sounds like a good M\B CPU combo to recommend for a new system. Even for software stepping.

It is a quite old single core Pentium processor.

I thought it was this
ark.intel.com/content/www/us/en/ark/prod...-cache-4-00-ghz.html
M\B is a socket 1200

Single core at 4 GHz should have raised an alarm, but i guess my alarms are off today !
