About a week ago, on Ubuntu 9.04, Thunderbird suddenly became slow as molasses, and the malaise seemed to spread to other apps when thunderbird was running. Despite the fact that top did not indicate anything amiss.
I noticed that primary hard drive was starting to show errors, and it had slipped back int udma5 mode, so I decided to replace the hard drive and do a fresh install of Ubuntu 9.10 at the same time.
Brought over .mozilla-thunderbird from my old disk, went through it and removed all the .msf files so the indexes would be rebuilt on the new drive, and started thunderbird up. Even after waiting for all the indexes to be rebuilt, the problem remains. When thunderbird is running, the system is slow, and it is VERY slow to change windows between thunderbird and any application.
Been googling, and so far, all I can find is the .msf removal suggestion...starting to wonder if there was some recent Ubuntu update that is playing mokey business.
Thanks if you have any insight!
