Multi-threaded operations run single threaded on remote machines

If a multi-threaded operation is started from a gem running on a machine
that is remote from the stone, the operation will be performed by one thread,
regardless of the number of threads specified.  This is due to limitations
in the pageserver repository I/O.

Workaround

If you wish to use multi-threaded operations for performance, ensure that
you are running on a machine local to the stone.  You can check this by
executing System sessionIsOnStoneHost
