Does anyone have any tips for performance tuning a reagent/re-frame application they can share? We're running into very slow rendering performance when changing pages on Firefox on Windows (ie sometimes several seconds) which, though still noticeably laggy, don't seem to be anywhere near as much of a problem in Chrome.
Unfortunately I can't share the codebase, but here's what we've been trying so far: Using React.addons.Perf to identify components that take more data than they need as arguments - i.e their render function is called with changed data but they don't end up generating different markup. This has helped us reduce *re-render* performance, but doesn't help us much on initial page render, where is where our performance problems mainly lie. Wrapping all our subscriptions using our own [custom register sub function](https://gist.github.com/rsslldnphy/5c937167380dd3442076) to track how many times each subscription is called, how long it takes etc, to reduce duplicated work and highlight inefficiences. This has helped us a bit, but slowness still remains. To give a slightly better UX when moving between pages, we first update the app state with a key that causes a loading spinner to appear, then call reagent/flush to make sure it's rendered, *then* update the app state again to trigger the change to the new page. This still ends up being a bit jerky however (the gif often freezes while the page is rendering, or itself takes a while to appear) so any better suggestions would be very welcome. Thanks in advance for your suggestions.
