Hello, With 8 users or less your server is doing 2600 inserts per second ? And each insert is a new database transaction ? First of all, I think that ain't bad at all !
Are you using a database connection pool ? Check the size of the pool. Since you don't have problems when you don't perform db operations, I think your problem is not related to MINA. The bottleneck in our MINA based server also turned out to be Oracle, more specifically the number of commits that Oracle could do per second. I am not saying that Oracle is bad (quite the opposite) just that I think that's where you should look: it has A LOT of tuning options.
