My suggestions would be to collect the uptodate statistics before you start analyzing the problem. Then, enable statspack every 15min. during business peak hours. Once you get the statspack report, review the top 5 timed waits and expensive queries from the statspack. If you feel, only few queries causing the problem, tuning those queries would sometimes salve the entire issue.
Before you start tuning, have a baseline, a target and then start proceeding. tuning is not something you have done once and it works forever, its a continous process.
