Usage
Lock overhead is the time spent creating, destroying,
acquiring, and releasing locks (as opposed to lock contention, which is the
time spent waiting for a lock held by another task). Think of lock overhead as
the cost of lock operations, assuming the lock is always available.
Usage of this option simulates parallel execution with
the assumption that lock overhead is zero for a specified site.
Example
Generate a Suitability report. Examine the annotated
sites
myAnnotatedSiteJ
and
myAnnotatedSiteX
for opportunities to reduce lock
overhead. Write the report to
stdout.
advisor --report=suitability --reduce-lock-overhead=myAnnotatedSiteJ,myAnnotatedSiteX --project-dir=./advi_results
