Increase server performance

[kumarbala]

Hi Experts,

Recently we are observing our apps getting slower from mashup side so we are planning to implement cache warming.Can  anyone please suggets what are the best methods from qlik admin point of view to increase the server performance irrespective of qlik & mashup side. Apart from cache warming is their any other possible suggestions to increase the server perfroamce.

Hi, 

You need to monitor your server, and if:

• You see CPU plateau instead of peak, increase core number and ram, with 1core for 8Go of RAM
• You see RAM overconsumption (more than 90% of the server available RAM), same as above
• You can preload apps with Preload task Creating preload tasks | Qlik Sense for administrators Help
• You can add a node to your infrastructure 
• You can check if any reload task (or manual reload) are performed as the same time of consumption usage, if yes best approach is to dedicate one node for consumption and one for reload 
• You can check latency between Qlik Sense node and Qlik File Share, must be <5ms, and I/O speed too
• You can check if any software like antivirus perform scan during Qlik Sense operations

And maybe some over tips 🙂

Best
