different "time capsule slow"

[sb1805]

Whenever my time machine backups to a time capsule are decently large, I get transfer rates over wireless of 2-4 MB/s...which seems to be the norm. But what I don't understand is when I only have very small backups taking place (ie if nothing really has changed since the last backup and I get 300kB or 2MB backups) they take much longer to complete than i'd expect given the speeds above. For example it might take 4 mins from 'backing up 2kB of 400kB' until it gets to the end at 'backing up 400kB of 400kB'. Has anyone else noticed slowdowns like this?

That is really odd. It shouldn't take that long - I wonder if the sparse file has become corrupt?

I know I was having issues and I just deleted all back-ups and re-ran a full backup. If you decide to do this, just make sure you don't need those back-up files.

yeah it's weird...right now it's doing the same thing again. is there some way to repair the drive, or have os x check if everything is ok?
