async_vs_serial Simple Node.js program to compare async default processing with serialised processing For serial / sequential processing, a list of work functions is provided, each calling next The implementation of next takes the frontmost work function off the list and executes it Handy for database processing where sequence needs to be preserved Simple enough to illustrate the async nature of Node.js Sample output : Default run > time ./async_vs_serial.js async RUNNING ASYNC >aaa >bbb >ccc <bbb took 50ms <ccc took 120ms <aaa took 220ms real 0m0.325s user 0m0.090s sys 0m0.012s Serial run > time ./async_vs_serial.js serial RUNNING SERIAL >aaa <aaa took 220ms >bbb <bbb took 51ms >ccc <ccc took 120ms real 0m0.479s user 0m0.075s sys 0m0.011s blog : quantblog.wordpress.com
