Absolutely Richard It changed the execution speed dramatically reducing the buffer size. I really still need the time to set up various tests and check it carefully trying to find the right size on my machine. Maybe 128k - we will see.
>From Bernd - in an internal mail - he worked on my script and made that happen changing the buffersize.: It is Windows. Same as you are reporting about Linux. Optimization here is the goal. Yes. But also I would like to optimize the code if that gives additional advantages. Also to be noted by Bernd, the speed also dramatically increases using an SSD. I am still using old fashioned hard drive (.
