Memory Cache vs Disk Cache

There is this interesting discussion during meeting just now, it’s about caching, there are people claim that Memory cache is faster then Disk cache without looking at the big picture.

The Infrastructure is build in this way, the memory cache is not on web server itself, the memory cache is using memory on the storage server which no need too much processing power, theoretical Memory cache did perform better but now on this infra, the problem is not Memory Cache vs Disk Cache already, it is more like network transfer + memory cache vs disk cache.

Interesting, i never think of that.
