+!!! info "Performance issue"
+    To ensure  Fed-BioMed performance in WSL2, be sure to use the native WSL2 Linux filesystem (in `/home/login`),
+    not the Windows filesystem (in `/mnt/c/Users/login`), both for cloning the library and storing datasets.
+    We experienced 10-50 time slower execution with native Windows filesystem.
+    This point is [documented by Microsoft](https://learn.microsoft.com/en-us/windows/wsl/compare-versions#exceptions-for-using-wsl-1-rather-than-wsl-2)
