I have already bumped that up quite a bit as well, but I still get many waits.

Does anyone have any idea how to improve performance for multiple inserts into a table that uses a sequence generated primary key?


Is the sequence cache set to an appropriately large value?

I have approximately 6 concurrent inserts per second into this table which causes the primary key index to become a hot block.  This in turn causes "buffer busy waits".
 
I have increased initrans, but am not sure where to go from here
 
Any ideas would be appreciated,
