shinyloadtest: static content loading for multiple concurrent users takes a long time

[ebreitmo]

Hello,

I use shinyloadtest (https://rstudio.github.io/shinyloadtest)/ to simulate multiple concurrent users for my app.
For e.g. 20 concurrent users the loading time of the static content (js, css) seems to increase linearly.
We use nginx as a proxy and websocket for the dynamic content (which disables caching).

Is there any way to optimize the static part?
Is it a configuration problem on our side or an R problem?

Thanks,
Elena
