Hi Dubravko,<br>
<br>
In the UK service, because we only have a limited number of processors<br>
(with lscpu) on our new platform, we set our FarmSize to 3 times the lscpu<br>
number, and it's certainly helped with throughput. So, I'd suggest setting<br>
yours to 16, just to see how that improves the throughput?<br>
<br>
Our old hardware actually had 12 and 16 processors (with 24 and 32 cores<br>
respectively) and in those instances we literally got away with just<br>
running the number of lscpu instances in the FarmSize.<br>
<br>
Hope that helps.<br>
<br>
Stefan<br>
