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.

SQLite
This is a simple benchmark of SQLite. At present this test profile just measures the time to perform a pre-defined number of insertions on an indexed database. Learn more via the OpenBenchmarking.org test page.
Flexible IO Tester
Fio is an advanced disk benchmark that depends upon the kernel's AIO access library. Learn more via the OpenBenchmarking.org test page.
IOzone
The IOzone benchmark tests the hard disk drive / file-system performance. Learn more via the OpenBenchmarking.org test page.
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.
Sockperf
This is a network socket API performance benchmark. Learn more via the OpenBenchmarking.org test page.
TTSIOD 3D Renderer
A portable GPL 3D software renderer that supports OpenMP and Intel Threading Building Blocks with many different rendering modes. This version does not use OpenGL but is entirely CPU/software based. Learn more via the OpenBenchmarking.org test page.
