Print Page - Weird behavior: performance drop after ~10 sec

I posted my max hash rate for my Core i7 on Windows 7 at https://www.bitcoin.org/wiki/doku.php?id=bitcoin_miners#khash_rate_reports just now. Maxes out around 2,450 khashes/sec.

Something odd, though:

Start Bitcoin (GUI or headless mode) with no CPU limit
After connect, performance goes to about ~2400khashes/sec
After about 10 seconds, performance drops to ~1350khashes/sec, and stays there
Change CPU limit to 1, then back to unlimited
Behavior above repeats itself

Anyone else seeing this? I tried shutting down other programs, but it didn't make any difference.
