Benchmarks With two Intel Quad-Core Clovertown processors and eight sticks of Kingston FB-DIMM DDR2 Phoronix set out to see the level of memory performance in an octal-core environment. Phoronix has tested the memory in single, dual, and quad memory channel configurations. Read the article to see how the Intel Xeon 5300 performs in various Fully Buffered Dual Inline Memory Module configurations.

where are server type benchmarks?

those are all toy benchmarks where the main loop in the code fits in l2 if not l1 cache, and the total working set is only 4GB, so nothing really taxing to anything but the cpu.

Well, if SPEC / SSL / Apache/PHP/MySQL / PostgreSQL / Java Webserving are not "server type benchmarks", I think you need to explain what do you mean by this term.

those are all toy benchmarks where the main loop in the code fits in l2 if not l1 cache

PostgreSQL or Apache core fits in 1-4Mb or 128Kb L1 cache? Man, I wish it were true!

Anyway, code data size has little to do with memory bandwith and latency limitations. So what's your point?

, and the total working set is only 4GB, so nothing really taxing to anything but the cpu.

I wonder, did you actually read the article? They tested 64bit systems ONLY running 64-bit Linux. WHere did you get this "4GB working set"?

I think you need to scroll past the LMBench benchmarks and look at the server benchmarks in the 2nd half of the document.
