One of the things that had been bugging me since my upgrade to Leopard on my MacBook Pro had been general performance – something I couldn’t figure out.
Last night, I noticed that the many smart mailboxes I had set up in Mail.app a long time ago (and never bothered to actually use!) had thousands of emails in them. Using the Activity Viewer in Mail, I noticed that a lot of time was being spent after retrieving my mail (every minute!) updating the smart mailboxes.
So, I ended up just deleting those smart mailboxes – one by one – and now things are much snappier – and I’m much happier! I suppose I could have also backed off the mail check frequency a bit and had the same effect. Smart mailboxes are great tools – but if you’re not using them, you might enjoy shedding their baggage.
