WaitForAllTasks spent a lot of time!

[sunyifeng83]

I have encountered a performance problem. When i simulate a faucet emitter with 1000 particles limit, the fps will drop obiviously with the particle nums adding. Finally the fps will dropped to less than 10fps. I have attached my configurations and the function WaitForAllTasks spent time. How can i get over the problem. Any help will be appreciated!
