For reference, your SHOW STATUS as a mysqlreport:
http://hackmysql.com/bobly.txt
227.41 questions/second, of which 99.26% are INSERT--that's quite a lot. An since it's been up for 12 days, this a pretty accurate average. When you're inserting records, what does mytop say your qps is? Everything else in that report looks good, except maybe for the read ratio which is 0.01, but since you do so few selects relatively, this probably doesn't matter much.
I would comment out:
server-id = 1
in your my.cnf unless you're replicating as this will cause MySQL to write bin logs and since you do so many inserts, MySQL will be spending a lot of time logging these inserts. In another post a few days ago, this turned out to be someone else's performance problem.
