We recently switched from c3p0 to BoneCP because we had some problems with C3p0 mainly some strange Exceptions we could not track down. So we just tried BoneCp. It works great! I can’t really see if it is faster but it seems to be much more reliable. We drive a very popular website in germany with peaks of 3000 page views per second. All of these page views are dynamic and needs a DB connection if the data is not in second level cache. We used the LazyDatasource Pattern. As you stated you don’t know who is using BoneCP, i can actually confirm: It is a joy, not a toy to run your app with BoneCP

@Service
@Transactional
public class SomeClassService{

public void writeToDb() {
//some code
}
@Transactional(readOnly=true)
public Object getFromDB() {
//some code
}
}
