The attached patch modifies store.scm to buffer all writes, so that won’t happenany more. I’m seeing about ~40% speedup (6.194s vs 10.075s for the best out offive runs) for `GUIX_DAEMON_SOCKET=ssh://localhost guix environment guix --true`, but it also seems to have a negative impact on UNIX domain socketcommunication by ~10% (1.561s vs 1.385s). For the notorious r-learnr packageit’s still ~20% better (ssh, 16.620/21.418) and only ~3% worse (unix,11.489/11.199). Keep in mind localhost has a much larger MTU and much lowerlatency than usual networks though. It might benefit from having an even biggerwrite buffer (64k vs. currently 8k).
