Find the size of all relevant caches when doing I/O
Clash Royale CLAN TAG#URR8PPP
So, I'm looking at the stats from iostat, which updates every few seconds, and I see that I/O to device happens in bulks, say, around 40M/s, once every half a minute or so.
I'm debugging an application, which, I assume, should write in 64K blocks at a much higher rate. So, I assume, there's some caching going on.
Thus, my question: how do I find who are the caching entities, and what is the cache size?
To remove some players from this equation: it is not filesystem, the device that is being written to doesn't have any filesystem on it. Just a bare iSCSI disk in cloud.
