ABSTRACT:
One embodiment disclosed relates to a method of finding lock contention in an application with concurrent threads. Status data is retrieved by periodically sampling status of said threads. The periodically-sampled status data is accumulated, and the lock contention is statistically found from the accumulated status data. The status data may include location information that is usable to pinpoint the lock contention.
