No probs. Speaking from personal experience elsewhere I know that when you have a problem and you start googling for solutions, you can end up grasping at any suggestion you come across in the hope it is the magic answer you were looking for. I would have hated to see future users come across this thread and draw incorrect conclusions like "plugins will slow down calibre so they are bad".

Startup time, search performance and metadata download are three discrete and entirely separate software tasks. They all have individual solutions to resolve any problems with. Disabling slower metadata download plugins like Overdrive (if you had it enabled which is not the default) is a good suggestion to increase the metadata download performance but it will make no difference to calibre startup or search times.

It would certainly be "possible" to write a GUI plugin that poorly impacts calibre's startup times, but as I said above that is certainly not the case with the plugins I have published/use. On a 3-yr old Win 7 64-bit machine with a not particularly fast hard-drive startup time is around 5 secs for 11K books and about 10 seconds for a 33K book library from memory. I am sure I could make that faster by using an SSD and a newer machine but it is good enough for me - and certainly not the "minutes" that some users come on the forums to report. So if you have a library that is taking considerably longer to load then as the saying goes, "these are not the droids you are looking for..."
