I have reported about Intellij becoming very slow after a while ( version 10 ) in this thread:
and I believe this has to do with the constant looking for Gems because it keeps turning up at the bottom and try to match or highlight my code using the Rails plugin or something else.
"Scanning for gems requirements" ..
You can see this very quickly at the bottom when editing for example a controller. It gets triggered on every key down or up... not just on save...
I am guessing this is the reason to why Intellij becomes incredibly slow after 2-3 hours and needs to be restarted.
How can I turn this off? I do not need anything to scan for gems all the time.
