Ubuntu Linux performance runs using Windows Subsystem for Linux 2 (WSL2) under the next one Windows 11 The output closely matched the performance of the cast performed on bare metal, according to a new benchmark.
Monitoring in their benchmark compare Windows 11 to Linux, Phoronix tried to evaluate the improvements of the WSL2 subsystems of the next version of Windows, comparing them to the natives Ubuntu 20.04, and future installations of Ubuntu 21.10.
“Out of 130 tests in total, Windows 11 WSL2 Ubuntu 20.04 LTS managed to run at 94% of the speed of bare metal Ubuntu 20.04 LTS on the same system,” observes Phoronix.
Impressed by the performance, Phoronix makes a point of highlighting the CPU / system references where WSL2 provided performance comparable to that of the Ubuntu installation in native mode.
Encouraging results
The tests were performed using the open source Phoronix test suite running on a AMD Ryzen 9 5900X system with ASUS ROG CROSSHAIR VIII HERO motherboard equipped with 16 GB of RAM, 1 TB WD_BLACK SN850 NVMe SSD, and one GeForce RTX 3090 Graphic card.
The tests revealed interesting results. For example, under heavy workloads WSL2 showed some overhead compared to Ubuntu Linux bare metal as expected. However, for some HPC workloads like Rodinia, Ubuntu 20.04 LTS under WSL 2 performed almost at the same level as Ubuntu bare metal and in some cases even won out.
In a similar vein, the performance of most moderate processor workloads that do not consume I / O or memory, the performance of WSL2 Ubuntu was virtually the same as its bare metal counterpart.
“The Windows Subsystem for Linux 2 has matured quite well overall and for most workloads it offers acceptable performance on Windows 11,” concludes Phoronix, noting that although the tests were performed on a version of the Windows 11 “Dev†channel still in preparation (Windows 11 22454.1000), they will be repeated once Windows 11 is released in October.
Going through Phoronix
