Shiny reloads data after any user input about pct-shiny

[audev]

On the same line, I think shiny updates the map base image when lines are re-rendered, even without panning/zooming. If that is function [updatescene], it accounts for ~60-70% of cpu time.

@audev interesting. Do you mean 60-70% of cpu on the client or the server side? It's an issue in any case but less of an issue if it's server side because the basemap is served externally.

[audev]

No, on the client side (no idea on the server). In reality it's just a count of groups of functions on the browser, so no more than a 'relatively' bad proxy.
Top 2 functions: [updateScene], 60% counts (~10% time), and onreadystatechange: 15% counts (~80% time).

@Robinlovelace Could you deploy the app on the server, and then test it out how is it performing?

[usr110]

It'd be nice if everyone tests out the recent changes, and then see if it is working.

[Robinlovelace]

@usr110 looks OK to me - just deployed it and restarted shiny-server on geo8.

@Robinlovelace That's great, thanks!
