I just put up a new lettered version of LiS-2.17. Do not consider this production. It has quite a bit of lock optimization in it.
You can enable the lock contention code by "streams -D0x08". Run a test and then use "streams -L" to see the four most contended-for locks. If your code has dynamically allocated locks that get deallocated at the end of the test they won't show up in the output, so you may want to do some "streams -L" during the run to catch those.
The lock contention tracking can be enabled even if you enable all the performance enhancements. That is, you don't need the "development" version to enable this.
Let me know how the oprofile work goes.
