Not sure if it's your case but the order of MGS' NIDs when mounting matters:
[root at my-ms-01xx-yy ~]# time mount -t lustre 10.210.1.101 at tcp:10.210.1.102 at tcp:/fs2 /scratch
[root at my-ms-01xx-yy ~]# time mount -t lustre 10.210.1.102 at tcp:10.210.1.101 at tcp:/fs2 /scratch
Since the MGS is running on the node having the IP "10.210.1.101", if we first try with the other one there seems to be a timeout of 25s.

One of our (recently built) 2.10.x filesystems is slow to mount on
clients (~20 seconds) whereas the others are nigh on instantaneous.
We saw this before with a 2.7 filesystem that went away after doing
<something unknown / filesystem upgrade> but we've no idea what.
Nothing obvious in the logs.
Does anyone have suggestions for what causes this, and how to make it
faster? It's annoying me as "something" isn't right but I can't
