Ello all, I'm back at uni and my computer feels horribly sluggish. I've been poking around in Task Manager and it says that the "Commit Charge" is 679MB - (this is with Outlook 2003 and Firebird running). Back home this was only 160MB! Can anyone suggest what on earth may be going on? I'm going to google my way down the running processes list, but I'm rather confused at the sheer size of the memory usage. The system does have 768MB, but I can't believe there's so much going on. Any advice much appreciated. Thanks Edit~ The most memory used by an individual program at time of last measurement was 15MB by the way, and though Outlook can jump up to 50MB sometimes (iTunes is no slouch either) the commit charge stays gigantic even when they're closed. Services running on my system include: mySQL, Apache and MailEnable SMTP server. The POP/Mailing list server of Mail Enable is disabled though, as is the iPodHelper of iTunes. I do run Yz'Dock/Shadow/Toolbar too but again, how any of this can add up to the 500MB extra usage over my families machine at home is unfathomable.
