System painfully slow on 2.6.24.5

[cmouse]

It seems that for some reason my system became painfully slow after upgrading. Everything is horribly slow and merely compiling new kernel to disable most likely suspect (PAX memory feature) seems to take forever. It seems to compile with average speed of 1 file per 5 seconds.

And disabled non-executable memory protection features and now everything works as normal.

have you read the config help about PAGEEXEC's impact on P4 (no-NX bit)?

No, but I will now.
