Up first for testing was the Intel Core i3 10100 for seeing the impact of FSGSBASE by default on Linux 5.9 compared to disable it...

One of the real-world workloads we've seen benefit throughout our FSGSBASE patch testing over time has been Redis. With Linux 5.9 on this Core i3 box, Redis continues to see nice improvements in performance. Granted, not many will be running Redis on a Core i3, but we have seen similar gains for Xeon too.

For a wide variety of I/O tests, FSGSBASE does help elevate the performance on Linux 5.9.

The WireGuard secure VPN tunnel / Linux network test performance improved slightly.

For other workloads, the results varied. The most exciting area seen so far has been the I/O performance but particularly when looking at server workloads there are more opportunities for benefit, so stay tuned on those numbers.
