Can you tell more details? How much data your scan is going to retrieve? What is the time taken in each attempt ?
Can you observe the cache hit ratio? What is the memory avail in RS?.....Also the cluster details and regions

I tried to run twice the same scan on my table data. I expected time to
improve but that was not the case.
What am I doing wrong? I set "scan.setCacheBlocks(true);" before the
first scanning job to put if not all at least some block in memory.
