How can I found out my real TLB size (including offset) ? What I want to do is to check the TLB size for 4KB and discover how many entries would I have if others size like 16KB, 32KB, 64KB... were supported

Good argument Schmide, So as Huge pages TLB have a large offset it seems fair to compare the Huge Page against 4KB even if when number of TLB entries are different. thanks

I am trying to check if linux THP can really provide performance gains for different workloads. But as TLB entries are different for 4KB and 2MB, I am affraid that comparison will not show exactly how better huge page is.

So comparing performance between 4KB and 2MB page size in the same CPU is not valid as the TLB entries may vary?

Hi I am trying to find out why the TLB size from my CPU changes depending from the page size: $ cpuid | grep -i tlb cache and TLB information (2): 0x5a: data TLB: 2M/4M pages, 4-way, 32 entries 0x55: instruction TLB: 2M/4M pages, fully, 7 entries 0x03: data...
