QLIK SENSE Enterprise has low performance on VM

[hillarynyawate]

Hi I have installed Qlik sense on a virtual box in a Linux server , but the performance of the dashboards keeps on fluctuating whereby the engine service would stop and even after restarting it, the Utilization of the CPU is consumed to 95% and above. My query is, how would I ensure that I configure qlik sense on a Virtual machine and still use the same server for other activities that will run on linux and maintain a stable Qlik environment?

Hi @hillarynyawate ,

What are the spec of your VM?

You need a minimum of 4 cores and 8 Gb of ram.

Hi @Boris_I 

I use VirtualBox with the following specs:

Total Physical Memory: 111,163 MB
Available Physical Memory: 98,307 MB
Virtual Memory: Max Size: 127,035 MB

Hi @hillarynyawate ,

And many cores are allocated for the Sense server?

@Boris_I 

Processor(s): 1 Processor(s) Installed.

Hint: 1 processor and your CPU consumption is at 95%, you need at least 4 cores

Its also using a hypervisor

Especially if you are thinking of running other things on the same server.
CPU starvation is almost a given if you only have one CPU.
You need to account for all CPU and memory loads on all virtual machines on that Linux box.
Idealy Qlik should have dedicated resources.

what if I need to share the same server with other platforms like Databses, whats the ideal solution, should more resources be assigned to the Virtual box? and what would be the max recommended?

Firstly Qlik Sense is only supported on windows.  Here is Qlik Sense System Requirement. 

Secondly, Qlik Sense engine tends to be hungry for CPU & memory. It is always the supported and best practice to have dedicated server for Qlik Sense.  Combining them on shared resources can be a bad thing but it could also work.  It all depends on how much resources you have and they (database & Qlik) need simultaneously.
Shared resources dynamically allocated sounds great but is not if both systems need the resources at the same time.

But PROD should only has dedicated server.
