Re: [Gems-users] Warm-up Cache

["Derek Hower" <drh5@xxxxxxxxxxx>]

I believe the warmup files do not actually snapshot cache state, but
instead capture the stream of memory references from the beginning of
a simulation until the end of the warmup period.  Because ruby will
warm up the caches by replaying the saved references, you can use the
same warmup file for any arbitrary simulated cache hierarchy.
