An Early Look At Windows 11 WSL2 Performance Against Ubuntu Linux

When I/O is involved, the WSL2 performance tends to still be much slower than having a bare metal Linux installation but at least better than the original WSL (WSL1) performance.

It ultimately comes down to what workloads you intend to run under Windows Subsystem for Linux and how much I/O is involved for how well it can perform relative to a bare metal Linux installation.

See more of the early Windows 11 WSL2 benchmarks via this OpenBenchmarking.org result file. Again, keep in mind this is still an early Windows 11 build and when the official Microsoft Windows 11 debut happens later in 2021 I will be back around with plenty more benchmarks on multiple systems once the Windows 11 RTM release is available. Also at that stage the graphics/GPU support within WSL2 should be more mature for Linux benchmarking. In any case at least for CPU-heavy workloads the WSL2 performance continues to be quite similar to Ubuntu Linux itself.
