Internally SQLite uses locks to serialize calls by multiple threads. If 
multiple threads are trying to access it at once, that will increase overhead 
since the locks have to control the access. Usually this isn't noticeable since 
the overhead for acquiring a single lock is very low, but it depends on how 
many calls are being made.

You'll need to give more details of what calls you're making, on how many 
threads, and how many times they're called.
