My observations: The web version of Kaoto has no significant footprint on the system performance. I tried with only canvas open and also with catalog open and with both tests my system was continuing between 3 and 5% system load.

VS Code: VS Code itself has already quite some footprint. When invoking "Create yaml route" jbang then takes quite a peak in the resource consumption for a limited time. After that the system load is at 6-10%. Opening up the catalog takes a short peak in performance and returns quickly to 6-10%.

Tested on Win11 with AMD Ryzen 5 7600 6 Core CPU / 12 VCores with 64 GB RAM and a NVidia 4060TI card, so a rather strong setup.

It is even worse for me now, the CPU load stays above 50%, here with Firefox: image

Fedora 39 Firefox 124.0.1

similar issue with Chrome 123.0.6312.86 : image

Tested on my P1 now and I cannot reproduce this. Wondering if that is maybe a local problem on your end.

Update: When using the top command I can monitor similar values but I think that is maybe a misinterpretation of values. If you check for instance gnome-system-monitor or the mpstat command you will see that the CPU utilization is around 6% in my case for the whole Firefox process.

I know that it triggers the fan of my laptop so there are good chance that it is more than 6%.
