Description Mohit Agrawal 2021-09-22 05:00:48 UTC 
The _gf(c|m)alloc and __gf_free memory allocation api calls gf_mem_set_acct_info function to save memory accounting on xlator and to update the record it takes lock.During testing we have observed the mem_acct mutex has contention.

Solution: To avoid contention make it lock free and the performance data is available at github issue #2771(https://github.com/gluster/glusterfs/issues/2771)
