I compared to performance of TieredCompilation vs. the standard
compilation using the Dacapo benchmarks.
The results are attached to this mail.
The benchmarks show a significantly reduced startup time with
Steady state performance is equal or better with TieredCcompilation
compared to standard compilation.
One exception: jython benchmark. For jython, TieredCompilation takes
until run 20 to come close
to the performance of standard compilation. The reason for this behavior
is to be determined.
x-axis: number of runs of the benchmark executed in the same JVM instance.
y-axis: benchmark execution time in milliseconds.
no_tiered (standard compilation) and tiered (TieredCompilation enabled)
are executed in
seperate JVM instances.
