Since the 4.4.0 release, R can make use of libdeflate. From the release notes: > memCompress() and memDecompress() will use the libdeflate library (https://github.com/ebiggers/libdeflate) if installed. This uses the same type of compression for type = "gzip" but is 1.5-2x faster than the system libz library on some common platfor...

Hi all, I am running Ubuntu 20.04.6 (focal) (yes, planning to upgrade soon) and just updated to 4.4.1. However, the process did not quite go as smoothly.
