thank you very much. I know performances worsen, but I need to simulate a simple system having either lot of reads or lot of writes. How could I do it? (if I'm not off-topic).

Hello Giovanni

There are really three answers to this question...

First, you can disable the cache before mounting by setting
dev->param.n_caches to zero. In Linux you can mount with -o no-cache.

Secondly, you can empty the current cache by using sync().

There is no way to disable the cache once a partition is mounted.

Why do you want to disable the cache? It generally provides speed advantages.
