I need to know how the directories of a Linux system are used, in relation to their approximate read/write behaviour in time.
So far I have not been able to find any references. Can anybody provide some links?
The reason of my interested is due to the fact I have to install Linux on a system with a small, fast and expensive SSD (mainly for read operations), a large, slow and cheap SSD (read and write) and a RAM-disk (temporaries).
I know the answer depends on the kind of activity (mine is mainly a development one), but as I wrote I only need approximate values.
Ideally this is what I am looking for:
| Directory | Size | read/write operations ratio | average N operations per second |
What I would do (without being sure about it) is:
Small and fast SSD: /bin, /boot, /dev?, /etc, /home, /lib, /opt, /root, /sbin, /usr Large and slow SSD: /lost+found, /media, /mnt, /srv, /tmp, /var RAM disk: /proc?, /dev?, /run
Is this reasonable?
