As I did say originally in this thread, the first cluster really does take a while. I'm quite surprised at the 14 hour mark, though, as when I personally ran speed tests (using Beta 28.4), importing 1,322,364 hands in 8946 files, PT3 took 4 hours and 21 minutes to complete the import, for an import time of 84.4 hands per second. The full housekeeping took an additional 1 hour and 31 minutes, so the total import and housekeeping time for PT3 was 5 hours and 52 minutes, or 62.6 hands per second, which is a whole lot less than you.
Were you using a whole lot of very small files? I suppose if you had a ton of very small files and a lot of regulars at the stake in question, the cluster might have a whole lot more work to do to get things orderly, but I'm not sure.
Either way now that it's done, the next cluster really ought to take less time. Updating the cache will take about as long - do you have a lot of custom stats? That would increase cache update time.
