I am facing the database connection error on my wordpress blog , my visitors are continously increasing and i am facing this problem more frequently, i reported it to the hostmonster also again again, they changed the file system which results in decrease of the recovery time , now my wordpress blog recovers in 2 to 4 minutes from this problem , but now it is becoming more and more frequent. I am helpless , i m a newbie and don't know anything about the database and CPU throttling , they told me that this is due to excessive queries from the users which causes the CPU throtling , they told me that I m required to optimize the database ........... please if anyone can guide me , If moving to dedicated server will solve this problem .........
