Openjpeg is a very quick running microbenchmark. Barely five seconds per invocation.
Topdown metrics also tough to see given the quick runtime but some higher frontend times with both latency and bandwidth

Intel metrics show a high amount of speculation though this is also perhaps with the short runtime.

Process overview suggests we mostly measure the overhead of the test suite itself though also looks like we quit prematurely.
