Yeah lots of things ...
Are your Exchange Servers and SQL servers on the same LAN as the BES?
How many Exchange Servers do you have with BES Users?
How large are your BES users mailboxes?
Do you have any 3rd party products integrated with Exchange? (A/V, Spam Filtering, Archival, Message Stubbing ...)
Run an ExBPA and see if anything comes up ...
Do a performance baseline if you can too
Can you fire up performance counters on your Exchange Servers?
What symptoms / problems are you seeing?
As far as adding more servers and doing load-balancing it all depends on your RPO / RTO / DR plans. Is BES a "Level 1" service that has to be up immediately? Can you stand a 2 hr outage? 4hr? 15 min? 5 min?
Without 3rd party software you can effectively do 10-15 minute recovery if you create scripts and have excellent monitoring. With it you'll be able to do ~5 mins.
If you've got 500 users and you're climbing with plans to hit 800 - 1000 ... its really time to look for a 2nd BES, if you're staying around the number you're currently at you can certainly get by with a single BES, but if you want higher availability ... get a 2nd BES.
What are your needs / requirements? ... lots of questions.
