Like clockwork, MacBook Pro freezes for about 30 seconds every 20-30 minutes... Why?

[QUOTE="GeoFan49, post: 1552369, member: 314949"] [B][I]Now we all know.. [/I][/B]Calculate Folder Sizes for a Directory Tree of about 100,000 files and 100 GB on a MacBook Pro (2.53 GHz Intel Core 2 Duo) with a 7200 RPM drive (1 TB, half full) takes about [B]10 minutes[/B], when the entire system is idle other than Finder running at 60-90% CPU. Also, making ANY change (even adding or removing an EMPTY folder) causes an entire recalc on the whole folder tree; but only IF the folder window is open, [I]even if the folder window is minimized. [/I][B] [U]CLOSING[/U][/B] the window instantly ceases the Finder Disc and CPU activity for the calculation. Meanwhile, CPU temp will rise from 50 C to 70 C (into the upper half of the normal range) when one of the dual CPUs is busy at 90% for more than a few minutes, but not enough temp rise to trigger higher RPM on the fan. Otherwise, Finder runs about 3%-5% CPU average, during idle time. Mac OS X 10.6.8 Finder behavior. [/QUOTE]
