What's the default block size in farmer benchmark prove test?

Support
1

What’s the default block size in benchmark prove test?

How can we change it ( for better performance, we need to tune the block size parameter)

2

Proving benchmark measures proving performance, it doesn’t produce blocks, there are no blocks involved, so your questions doesn’t make sense to me.

3

Will proving benchmark write to disk and read from disk?

4

It will read, but not write anything

5

I use strace to log the read syscall. I want to know how many bytes are read in prove.

The log shows very small amount of data was read. Is that all the data prove read?

Yes, thought your question kind of contains an answer already. If you are curious about such things, it might be good to start by reading Introduction | Autonomys Academy

7

Could you please show me the docs link about benchmark prove? I want to know the work flow of the prove test and what have been done in the test.

8

For that you should just look at the code. Proving is doing what the specification and Introduction | Autonomys Academy say it should do, benchmarking code only runs it in a loop to measure time.
