no longer working or reduced performance I am assuming Linux. Some of this is also true for Mac. Reduced performance, battery life for sure. If one has enough ram they can work around this by doing builds in a ram disk e.g. /dev/shm and then committing artifacts to the encrypted disk. Along that same line, if one is using tmpfs such as /dev/shm to do ephemeral work in ram then be sure that swap is either encrypted or disabled as tmpfs is swap-backed and one could leak sensitive information into unencrypted swap. MacOS by default does not or did not have a ram disk but you can manually mount one. Performance impact can be somewhat mitigated by ensuring the encryption used is AES and that the CPU supports the AES-NI instruction set and a modern kernel is being used. Really old kernels had a single encryption write thread. lscpu | grep --color -i aes # or grep --color -i aes /proc/cpuinfo Some proprietary encryption software can set exclusive locks on disks or files so unless you are using dm-crypt/LUKS2 that would be something to research ahead of time in the event you need direct-io access such as a database and even in those cases there is usually a configuration work-around.
