What are you talking about when you say you have mds in a region, afaik
only radosgw supports multisite and regions.
it sounds like you have a cluster spread out over a geographical area.
and this will have a massive impact on latency
what is the latency between all servers in the cluster ?
kind regards

time got reduced when MDS from the same region became active
Each region we have a MDS. OSD nodes are in one region and active MDS
is in another region . So that this delay.

The first thing to check is what kind of "ls" you're doing. Some
systems colorize ls by default, and that involves statting every file
in addition to listing the directory. Try with "ls --color=never".
It also helps to be more specific about what "too slow" means. How
many seconds, and how many files?
