Why WAFL create snapshot so fast

Currently Being Moderated

I have compared the speed of Symantec CFS with FAS, in case of huge number of files, CFS takes much more time.

I thinks possible cause is CFS use a lot of dirty memory, whereas FAS creates checkpoint every a few seconds, which flush all dirty to disks. but a large dirty cache will increase performance remarkably.

Other causes maybe come from desgin mechanism,  can anybody explain it in details, thanks.
