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
