What version of memcached is on each machine? memcached doesn't use processes, it's multi-threaded. Different versions may have a different number of background threads. In the latest version there should be at least:
- listener thread (main "process") - N worker threads - hash table maintenance thread - async log thread (for `watch` commands) - LRU maintainer thread - LRU crawler thread - slab rebalancer thread they're all idle unless they need to do work. LRU maintenance thread is probably the most active, since it executes LRU maintenance work deferred from the worker threads. Older versions have some of these threads, but they were not enabled by default until 1.5.0. -Dormando On Sat, 14 Dec 2019, Alireza Sanaee wrote: > Hello, > I'm running Memcached on two different machines with different > specifications.
