Have a server having performance issues when look at wait types my number #1 is
FT_IFTSHC_MUTEX281386.4
never seen this on any other servers

Any database on that server have Full Text Indexing enabled on it?
It's in Glenn's list of benign waits to ignore, so I'd just ignore it (lots of waits should be ignored as they're expected or benign)

It occurs when threads busy with full text operations wait for synchronisation.
