ICache test showing effect of batching on performance

I also check the logs a lot,  but this repeated logging is clutter.
why not just printing the size of the cache once at the end of the loop,  
also this is great logging as we cannot tell which test this is printed from, in the case where we are running multiple test in parallel and its even worse when we run the same test class with different setting in parallel,  the solution it to print the test id which must be unique
