I'm not familiar with what a "Vignette template" is.

Curl doesn't create multiple instances. Curl is a single tool running in a
single task.

"Each instance" ? That's some program starting many curls, that's not a curl
behaviour.

What if you use a single curl running from the command line, does the same
effect occur then? What if you use the -v option, can you spot anything
particular that happens when the unusual CPU utilization happens?

Curl usually does this splededly.
