It’s up to your OS to use memory as file system cache. Depending on your OS you may need to tune something, see your OS tuning guides for details. In nginx you may want to tune various buffer sizes if you have enough memory, e.g. output\_buffers, proxy\_buffers, fastcgi\_buffers and so on. This is not about file system cache, but may reduce disk load if properly tuned for your typical use pattern. Maxim D.
