Hmm. Today (after computer reboot) everything seems to be fine even with Ram cache. Even though this web font problem has been there for some days now. Dunno if during the day, Ram cache starts to act out for some reason causing these problems? But i actually found some sites (at least one) response faster with Disc cache than Ram cache, so i might use Disc cache. Have not found much of a speed differences between those two.
