Casino Games Optimization?

Did anyone notice how games are optimized in some casinos , and in some u can't even load it for a while?

I would transcribed this to amount of users at the time, but i see on some casino empty slots (in game room) so it's not capacity 

I had a real problem with some casinos with my laptop (which is ok,i5 gen,8gb ram) where my temp was 70+ in one casino when i play slot...

on other casinos same game 40-50 temp...

On Casino Guru also never had any issue

Why is this?

Is it that hard to optimize the website ? or is it something else? 

Jeg havde problemer med Betsoft i weekenden. (I to kasinoer af samme ejer)

Jeg ved ikke hvorfor.

De fortalte mig bare at "prøve senere"

no im not talking about providers, just for casinos in general... for example try to enter (without account  )

 meridianbet.rs and try to free play some games... they are so heavy to load...

also in some casinos i notice many times 'waiting to server to respond' and just spinning ..

So annoying ,especially when u loosing :D

And some casinos are so optimized it's enjoy to play.... 

Ja! Jeg ved det særlige casino, og du har ret.

Overdreven langsomt.
