Description William Brown 2024-03-28 02:23:33 UTC

rpm internally uses zstd for compression of resources. zstd supports multithreaded decompression which can greatly improve decompression times.

However rpm does not use this, meaning that on systems with high core counts, installs are constrained by the performance of a single core. 

zstd multi thread decompression should be enabled by default.
