One trick I remember using (~two years ago, so early LV) when handling click events was to put everything async/not needed to reply in a spawn() function.

But yes as soon as you're on the internet you'll often feel the delay if your app is interactive.

The problem is that it's a bit random, because the network and the VM performances are never totally linear.

I remember implementing a countdown (using 1s send_after()) that would work fine most of the time, but sometimes there would be some hiccup and the countdown would stall just a bit and then process the counter in an accelerated fashion, which was terrible from a UI point of view, so in the end I did it in JS except for the update once the end reached.
