I'd say run a timed test both ways.

My gut says keeping the map and mutex around
is faster than creating them for every read.
My philosophy is "thrashing" is a Bad Thing.
Doubly so with Windows Resources.

Only potential drawback to keeping them open
would be if the server-writes are slower because
the OS has to update all those open maps.
I don't think that's an actual problem however.

You could also run a server timed test with
the server constantly writting to see if there
is any writting difference between clients
with/without open maps.
