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 platforms:...

Dear Miguel Esteva, I couldn't get a Red Hat "ubi9" container to install enough dependencies to build R. Is there a way to reproduce your setup on a virtual machine somewhere?

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. 'sudo apt upgrade' ran but 'r-base-dev' was not updated because of a dependency issue: [08:57] ? wviechtb at wv-x5 ? ~/ ? sudo apt upgrade r-base-dev Reading package lists...
