I know I am a low-ranker contestant. But during the contest, it took me more than 2 minutes just to do something. And every 30 minutes I been logged out and it take me again 3 ~ 5 minutes to log-in. It is very annoy :( Please help me, why the codeforces was so slow. This is the second time I write this blog (The first was ignore by auto-log-out)
