theres no reason for you to be doing that stuff, sorry. it might make you think you know some stuff but really its just making your code less maintainable for the next person.

query times. the lower i get them the larger dataset i can provide realtime results for. if it provides a statistically significant latency reduction i'll do it and the next guy can eat a dick

i don't use firefox because it's a slow piece of poo poo, not because it uses memory. there's lots of valid reasons not to use firefox

the biggest thing we have done to optimize the performance of our ui: instead of sending an http request for pretty much every singular piece of data, we have one big mass query that returns most of the data we need in one request. one request usually takes less than 1 second, even when you query for multiple things at once, but make hundreds of less than 1 second queries and the user kinda notices
