During this time the task manager shows calibre using ~2% of the cpu (intermittently) with memory increasing in steps to 207,000K.
Lots of disk activity during this period.

I tried switching off the anti-virus but it makes no difference. This only happens on the first activation of calibre after starting the computer. all subsequent starts of calibre are within a few seconds.

Any thoughts??
@ericmjones - if you start calibre very soon after you start Windows, then the delay may be due to Windows (or some other 3rd party program) still doing its start up tasks - eg creating a restore point. I've also noticed that the indexer sometimes finds things to do at start up, but if its set to run at low priority (which is the default) it should yield to higher priority processes.

If above applies try waiting 10 minutes before starting calibre -- just to see what happens -- not suggesting that as a 'real' solution.

IMO running defrag on Win 7/NTFS is a waste of time, especially with the standard MS defragger. Defragging is done dynamically by Windows 7 when there's nothing else happening, unless its been turned off via the Policy Editor or a Registry hack. I believe some of the pay4me defraggers can make a difference on busy servers.

Are you sure that its calibre that's generating the disk i/o. Task Manager and tools like Process Explorer can help determine that.

Also calibre 2.20 had a fixup release, so you might want to try a fresh download and install from here ==>> Download calibre

One thing to try is to use Library->Remove library to 'detach' your library from calibre (don't worry it won't delete it as such) reboot and start calibre - if its still slow then that would 'indicate' that the disk i/o it not calibre rattling around in your library. You can 're-attach' the library via the Library->Create/Switch->Use existing library option

And you could also try a downgrade to a previous version. I'd suggest you backup first even though its not theoretically necessary, see ==>> How do I backup calibre?

What happens if you boot into Safe mode?

Also try starting calibre with the --ignore-plugins switch, see ==>> calibre command

Columns made from other columns have been known to generate slow calibre starts, but I am pretty certain they affect all calibre starts - not just the first time.
