 ### Improving Performance
 
-The by far slowest part of the `pfetch` execution time is counting the installed
-packages. For most package managers this is still very fast, but there are some
-(currently `nix` (and `zypper`, if `rpm-devel` is not installed)) that take
-~500ms to report installed packages, which takes away all performance benefits
-of the Rust version. If you have one or more of these installed, you can skip
-counting them by setting the `PF_FAST_PKG_COUNT` environment variable to any
-value.
+Counting packages of `zypper` can be sped up a lot by installing the `rpm-devel`
+package. If the `zypper` package count takes too long, it can be disabled by
+setting the `PF_FAST_PKG_COUNT` environment variable to any value.
