I recently bumped into a blog post where the person suggested to move the cache files to memory. My website creates cache files in html format and stores them on disk. With this method the folder is moved to memory apparently. It has significantly reduced the memory usage strangely.

Is this correct?

mount -t tmpfs -o size=1G,nr_inodes=10k,mode=0777,noatime,nodiratime tmpfs /path/to/cache/folder

I'm doing the same thing too in my /etc/fstab file, one example is:

tmpfs /var/cache/apache2/mod_disk_cache tmpfs defaults,noatime 0 0

Works like a charm for all kinds of temporary files.
A reboot will clear them.
