All -
Using FC3 RC5 (installed from the iso images at http://testing.fedora.redhat.com/tree/i386/iso/). My machine is a dual Xeon 1GHz with a gig of memory and Ultra160 disks - relatively snappy machine. My mail server is on my local network here at home. I am running evolution-2.0.2-3. I get my mail via IMAP.
I notice that often when I open a message Evolution takes several seconds (sometimes as many as 10-15) to display it. I also notice that the mail server hard drive light stays lit during this delay. It seems like somehow Evolution is re-indexing the folder or something for every message opened. The more messages in the IMAP folder, the longer the delay.
I don't recall this behavior in older versions of Evolution (1.4 or 2).
Any ideas how to make this stop?
