LiteSpeed Slower in FireFox, but Fast in Opera

[Sand]

I installed LiteSpeed and pages load average in FireFox and Chrome. However in Opera pages load fast.

Any suggestions? Is there a setting that makes LiteSpeed fast in all browsers?

it should not have any difference between browsers. mainly you will need to check header to ensure Litespeed cache enabled.

There is definitely a difference between browsers. Firefox doesn't support QUIC and has problems with HTTP/2 server push. Only Chrome and Opera have full HTTP/2 support.

Could you please enable cache (and ensure cache hit header before any testing), then take some screenshot for different browser for TTFB like the following to share with us?

What's the page load difference?
