We would like to offer to our users the pdf document conversion feature.
We chose the API provided by Collabora Online.
Here is the description of the VM where collaboraoffice 22.05.5-2 is installed:
- UBUNTU 20.04,
- 8 cpu Intel Xeon E5-2660 v3 2.60GHz
- 16 GB
The load tests show that collaboraoffice converts about 4 documents per second in the default configuration.
These results are consistent with the graph provided on this page : https://www.collaboraoffice.com/wp-content/uploads/2018/03/online-jodconverter-unoconv.png
Can we increase the number of documents processed per second by improving the power of the VM (which is already quite powerful).
Or is the best solution to decrease a little the power of a VM, but deploy several VMs behind a load balancer?
One last thing, we noticed a decrease of performance by upgrading collaboraoffice to 22.05.3-1 (from 21.06.30-1) and coolwsd to 22.05.3.1-1 (from 188.8.131.52-1).
Is it normal?
