Memory usage by using BlockingQueue in ThreadPoolExecutor
I noticed the size of each Runnable object is around 600KB. I am using the BlockingQueue with fix size of 10000. From the logging message, I saw all the 9864 objects had put into the queue. I did not see any the memory usage drastically increased. Should the queue be consuming 6GB (600KB x 9864) of memory?
