real world challenges using hibernate

1) performance. Hierbernate holds up well for mid-sized databases. For one GS system, we employ 3 techniques
 
* configuation on cachsing, lazy loading etc
* customize important queries using HQL
* hand-written SQL, when the generated SQL isn't optimized, but this tends to disable builtin performance features such as caching.
 
2) doens't work easily with stored procedures
 
3) if another db operation is already coded using jdbc, then one transaction can't easily span both
