Quote from NetTecture:
You should be aware that the DAX mentioned is - hm - not exactly busy compared to example to the ES.
Suggestion:
Please keep task manager open, or record CPU utilization. Look for a 100% spike when it lags. YOu should see the Ninja process eating all your CPU.
Oh, with multi core... the 100% is 100%/core numbers - basically you want one core going 100%.
The CPU usage with all applications is between min 5% max 25%
What you get as Zen-Fire is actually another technology, repackaged. They put their own name on it.
