Lately we have moved the qlikview server into a virtual environment, we have 250GB RAM and more CPUs than the original server. however we have noticed a drawback in the reload performance, it is taking now more than 40-50% compared to physical server.
do you have any recommendation regarding virtual server configuration? or have you faced this drawback on virtual server and therefore it is not recommended?
at the same time, you will not have more than 3-4 tasks running. however two of the tasks takes a lot of time to reload and uses 300million+ as total rows and contains heavy execution in the script, so the time for those 2 takes 12 hours and 5 hours.
