Re: [Cppcms-users] Big cache

[Artyom B. <art...@ya...>]

See, you don't cache objects of 500MB in memory...

Caching system is designed for pages and other objects of reasonable size
that their generation is costly,

Also remember that saving objects to cache and using it from cache involves some
memcpy... and than serving.

if you want to serve huge files/data (and cache them) it is much better to use file system for this.

Put them on disk and tell lighttpd, nginx or even apache to serve them, it would do it much better.

For example lighttpd would know to transfer them using sendfile directly from disk to socket
without even copying the data to user space.
