Close Client During Game Problem

I've been using the close client during game option as having the client open during game almost cuts my fps in half (I only get about 25-30 normally). However, at the end of games, it takes upwards from 5-10 minutes to reload the client into the post-game lobby screen. I usually just force end the client and relog, but with the new honour system coming in, I can see this being a problem where I cannot honour others after games. Is anyone else having this problem, or is it just me?
