kaspergrubbe / jemalloc5.rb
Created July 26, 2022 18:47
Tuning Jemalloc 5
# Inspiration: https://twitter.com/wgjordan/status/1440574986264006659
jemalloc_conf = {
# Maximum number of arenas to use for automatic multiplexing of threads and arenas.
# The default is four times the number of CPUs, or one if there is a single CPU.
narenas: 2,
# Enabling jemalloc background threads generally improves the tail latency for application threads,
# since unused memory purging is shifted to the dedicated background threads.
# In addition, unintended purging delay caused by application inactivity is avoided with background threads.
