If you use compressed tablebases, then the first thing it has to do is open every tablebase file, and grab the decompression indices it needs. This is several megabytes of data if you have _all_ the 3-4-5 piece files. If you have a slow disk, this is even worse. And no, you can't avoid this, because before you can probe, the decompression tables have to be prepared. It makes more sense to do this _before_ the game starts, rather than at a critical point when there is little time left on the clock in the endgame...
