Ubuntu 18.04 L1TF Foreshadow VM Testing

Tests done from an Ubuntu 18.04 LTS x86_64 dual Xeon Gold 6138 Tyan server (the one frequently used in other Phoronix benchmarks). Host and VM using the Ubuntu packages including its patched 4.15 based kernel. Mitigation levels/tunables done after reboot each time from the bare metal system. VM was lone resource intensive process on the server and configured to access 80% of the host system's CPU resources, Tests by Michael Larabel for a future article.

Compile Bench

Compilebench tries to age a filesystem by simulating some of the disk IO common in creating, compiling, patching, stating and reading kernel trees. It indirectly measures how well filesystems can maintain directory locality as the disk fills up and directories age. This current test is setup to use the makej mode with 10 initial directories Learn more via the OpenBenchmarking.org test page.
