This PR replaces the data-structure
SynchronousQueue
with the data-structureLinkedBlockingDeque
when callingnew ThreadPoolExecutor(...)
in the classNamedDaemonPool
.The motivation for this change is an observed performance increase: based purely on empirical testing, loading an OPI with on the order of 50 symbol widgets each with on the order of 10 different SVG files, the performance is dramatically improved when a
LinkedBlockingDeque
is used instead of aSynchronousQueue
. I have observed a performance increase both on Windows and on Linux. I have not tested the change on Mac OS.
