I'm trying to determine if my application will perform better on a 3.06GHz processor with 1MB cache as compared to a 3.06GHz processor with 512kb cache. Thank you,</DIV> <DIV></DIV> <DIV>Todd</DIV> <DIV></DIV> Sat, 22 Nov 2003 05:28:56 GMT https://community.intel.com/t5/Analyzers/L2-cache/m-p/979958#M9953 tahutchinson_99 2003-11-22T05:28:56Z https://community.intel.com/t5/Analyzers/L2-cache/m-p/979959#M9954 <DIV></DIV> <P>Todd, </P> <P>I'm not sure I know the exact answer to your question, but what really lead to performance degradation is the L2 cache misses.</P> <P>"2nd-level Cache Load Misses Retired" event looks like a good candidate to be measured and to be compared.</P> <P>Once it's rate decreases you should gain speedup foryour application.</P> <P>-Daniel</P> <DIV></DIV> Mon, 24 Nov 2003 20:59:06 GMT https://community.intel.com/t5/Analyzers/L2-cache/m-p/979959#M9954 Daniel_B_Intel2 2003-11-24T20:59:06Z
