The word is out. Just Google “Outlook 2007 is slow” and you'll see what I mean.
The Burton Group's Peter O'Kelly in a ComputerWorld article thinks the way Outlook handles RSS may be part of the problem, and he's right.
“Peter O'Kelly, an analyst at Burton Group in Midvale, Utah, said he thinks some of the sluggishness arises from Microsoft's decision to let users download RSS feed data into Outlook's local e-mail file in the form of either a .pst or .ost file.
Adding RSS feeds can quickly swell the in-boxes of many users to more than 2GB of data, according to O'Kelly. He said that causes Outlook 2007, especially when it's running on PCs that don't have large amounts of memory, to write to the hard drive much more often than it typically does — resulting in performance slowdowns. Hopefully, Microsoft will be able to better tune that part of the software before the next major release, O'Kelly said.”
