It’s possible but unlikely. The most likely reason is just bad code.

I’ve seen trading web ui that were as fast as native TT going back lots of years.

The most likely reason is that the ui designers do not understand the problem domain & therefore underemphasized refresh latency for something else.

Interesting - so do you think it would be possible to have a JS/HTML5 app refresh at 60FPS?

Not an expert on what is possible in that space these days but FPS is actually not that important in trading guis because you don’t need the whole canvas to refresh like you do in something like a shooter.

You don’t have to redraw a lot of things on each event because ladders and the like are mostly static while graphs are only dynamic in the tails.

Without observing your specific use case it is impossible to know what is causing your perception of lag, but I’d be shocked if it was bare refresh rate.

I’d guess their crappy code is just pissing off and not doing anything for big stretches of time because it isn’t good.
