Mail under Mountain Lion is painfully slow / unusable

I guess I didn't reply that I did get rid of MacKeeper. & then some time in there I accidentally spilled water on my MacBookPro & ended up getting a new one. But the Apple Store people helped me get rid of it.

Also, as someone else posted, I think my problem was way too many emails. I tend to keep my emails & so they accumulate. As the other person said, was not a problem w Snow Leopard but assuming its the old issue of newer software adds more bells & whistles & thus uses more memory.

I agressively was deleting emails--thousands of them.

I can't remember how much of that was before I got my new MacBookPro or after. But mail does seem to be working fine now. & when I got this new one, they used my Time Machine backup to restore all my stuff onto the new Mac--even Parallels & Windows 7 & Outlook (although later I had Windows telling me it wasn't valid software & was going in circles on that w the people at Microsoft that I needed to talk to gone for the weekend. But then all of a sudden it was solved & I don't even know how.

So the new one should have had the same stuff as was on the old one.

& just checked the count & it looks like I have over 72k emails on my Mac--many of them very old & not really used unless I want to look up something from years ago. But inbox has 27k+ so maybe the other very old ones are in a place that is not being used & so not slowing it down--not sure just how that all works.

It shows I'm running 10.8.4 now. & its all working fine.

An additional factor is that I moved in May from S CA w cox very slow speed internet (I had the economy kind that they didn't even offer any more). Now in Portland, OR w Comcast & Speedtest just showed download 33.7 mbps & upload 5.87. & this is using wifi from right next to my telephony modem & wifi router.

I also suspect that w 4 Gb memory & using a lot of different programs open at the same time I may have been using most of the available memory which of course would slow things down.

worked very well, thank you!

A similar issue, though perhaps it should have its own thread. Installers generally look for all discs you might want to install the software on. They find your regular HD, and then spend the next couple of minutes hunting for other discs, when it should only take a moment to discover that there aren't any others. It's a pity there's no way to stop the search so it can go ahead installing on the disc that it has found!

Excellent, this is the answer to the problem with iCloud mail. Thanks I'm cured 🙂

Thank you dsjr! I'd tried the well documented terminal fix without success, but this contacts removal worked a treat. I'd noticed that my contacts had slowly but surely been creating subtle duplicates within the address fields over the past couple of months....goodness knows how as it wasn't the normal duplication of entries that we all had when icloud first came into existence. Removing the 'earthbound' address book completely and starting again has resolved it as the icloud version was still intact.

The last step that I haven't figured out is how to get the contacts back onto my Mac - at the moment the Contacts are only showing from iCloud not On My Mac. Anyone? I've tried switching on and off iCloud, and selecting merge contacts, but to no avail.

AF.

This worked for me

> sys pref

>network

>Advanced

> DNS

check DNS numbers are correct, mine was showing the router and greyed out so I added my IP specific numbers

>Restart (not sure if you need this step but I did it)

Page loading improved significantly from very slow to acceptable on some to blistering fast in others

AND emails just flew in/out really quickly

Also make sure you have the right ports for your IP because I had been given an alternate one to try and that upset the incoming messages

> port (you can find this by searching your the help section on your IP website)
