there are couple of setting and issues which I couldn't find any solution/explanation for.
I appreciate any comments.

to reduce this number (due to my storage space limitations), but I couldn't find any input
parameters to do this. I just wonder if this setting is possible ?

but . for example, what does "latency" means here? does it mean how long a read/write operation
is delayed until it is executed? in this case, what is the measure for actual read/write operation?
