Problem Note 17514: Job submissions to grid manager increasingly slow
When you submit several large jobs to the Grid Manager, performance
could be greatly affected: The client SAS® session could become slower
and slower when attempting to submit jobs.
This slow performance is due to a threading issue. A thread that is
created for each submitted job causes a bottleneck because each thread
acquires the same lock, which is the same lock that starts and stops
jobs. Each thread created, in turn, is creating a connection to the grid
monitoring server. As more and more jobs are submitted to the grid, more
and more threads get started and more and more threads are competing for
the same lock, starving the submission process resulting in SAS taking
longer and longer to submit jobs.
