openSUSE Tumbleweed gains optional x86-64-v3 optimization
Tumbleweed users who performed a distribution upgrade or zypper dup the last weeks on the rolling release with “recommended packages” enabled (the default) and matching hardware received a new package named patterns-glibc-hwcaps-x86_64_v3 automatically installed. This is a new Tumbleweed feature which will also automatically install the “recommended” package named with the -x86-64-v3 name suffix that provides the optimized version of the library.
“The performance optimizations people will gain from this change is the result of much effort and discussion,” said Douglas DeMaio, a member of the openSUSE release team. “The x86-64 architecture thread on the mailing list really drove the discussion and the results will immediately provide performance improvements for those with x86-64-v3 hardware. It would be great if people write about these improvements so the results can be shared among users of our rolling release.”
