Metadata memory usage may increase due to the use of huge pages. Suggested: background_thread:true when jemalloc managed threads can be allowed.Īllowing jemalloc to utilize transparent huge pages for its internal metadata usually reduces TLB misses significantly, especially for programs with large memory footprint and frequent allocation / deallocation activities. ![]() In addition, unintended purging delay caused by application inactivity is avoided with background threads. The weights of the model when working on the CPU are in RAM and the work can be accelerated by a little tuning.Įnabling jemalloc background threads generally improves the tail latency for application threads, since unused memory purging is shifted to the dedicated background threads.
