Opens on LibreOffice as well but plain text is easier to read.
I wonder how much of the measured performance increase is due to the
increased effective cache size and how much is the reduction in number of
instructions by the victim TLB mechanism. Wouldn't it be a more fair
measurement to use a bigger TLB size for the TLB only case that matches
the effective size of the TLB+victim case instead of using the same TLB
size for both?
