I'm used to restart Odoo server during module development every time I change a .py or .xml file. This is how I did it with OpenERP v7 and continued the same method in Odoo v8.
I was excited to learn about the new --auto-reload switch of odoo.py but unfortunately it didn't speed up the development a bit, quite the contrary really. This is because starting the Odoo v8 server takes so much longer than v7. I thought --auto-reload wouldn't do a full reload of the server, but apparently that's exactly what it does. The log is filled with "Create fields._column" entries:

... about a million times.
Is there a way to speed up launching the Odoo server without disabling the debug logging?
I'm actually quite curious about this too. On a sidenote, in V9 you will not need to reload the whole server and all files. They will create a new ORM which will automaticly load in all changes! Which means no restarting and reloading and no downtime!
@Yenthe Did this happen in v9? If not, is it on the agenda for v10?
@Seba it is not in V9 and there hasn't been any mention about this anymore, so I guess they silently dropped the idea.
