Description

Fixing the type-check scalability issue on the DefaultProducerCache may offer a significant performance gain:

 

--- 4.0.0-SNAPSHOT (w/ single shot initialization check + local cache)
Minimum: 652933.0
Maximum: 763599.0
Mean: 720940.8750000001
Geometric mean: 720782.7857395237
Standard deviation: 14897.378438658043
-- 4.0.0-SNAPSHOT (w/ single shot initialization check) 
Minimum: 604363.0
Maximum: 738706.0
Mean: 690079.2589285716
Geometric mean: 689914.539795926
Standard deviation: 14777.32031672733

 

 

Unfortunately simple patches to fix access to the cache (such as c8d36cb1ddb93331cbecb0efa10586737f1d72c6) cause side effects (i.e.; DefaultProducerCacheTest fails). So, we might need to try a different approach.
