Last year a new kernel feature merged in Linux 6.6 was multi-grain(ed) timestamps for file-systems as a means of better timestamp handling originally for NFS compared to the existing coarse-grained timestamps with the once per jiffy timestamps being used for invalidating NFS caches. But multi-grain timestamps was reverted just weeks after landing in the mainline kernel due to corner cases like a newer file with a coarse-grained timestamp appearing earlier than another file with a fine-grained timestamp. Due to subtle bugs like that, multi-grain timestamps were dropped before Linux 6.6 was even released while now there is a revised attempt...

When testing Intel's aggressive software Linux optimizations shipped by way of their in-house Clear Linux distribution, I am most often testing it on their high core count Xeon processors with AVX-512... Over the years in dozens of Phoronix articles there have been countless metrics showing off the out-of-the-box performance benefits from leveraging software built for higher x86_64 micro-architecture feature levels, employing compiler-based function multi-versioning, and the other extensive performance tuning carried out by Intel software engineers. But now with the Intel Xeon 6700E "Sierra Forest" series now being available for these all-E-core server processors, I was curious about quantifying the Clear Linux benefits over the likes of Ubuntu Linux. Here are those benchmarks for those curious about the difference.
