That means that the server is very slow to respond.
TTFB stands for "time to first byte" and it shows the amount of time that the server took to receive the request, do any server-side processing it needs, the respond with the first bytes of the page.
Take a look at the server to optimize queries, speed up file access, reduce load, scale by increasing the number of processes, or any number of other things.

Subject: 1930 24G, slow TTFB, something wrong
Hey,
just got my self a 1930 24G running my homenet with a AP22 and AP11.
So far so good but one thing is really weird and I'm short before returning the switch:
All Websites everything I open on the Cabled connection is really slow. It's not the Bandwidth; Once the connection is there everything is fast but the "handshake" initial time until the website load (Time to first byte) feels like on a 56k Modem.
It's definitly a Problem with the 1930, I have my old switch (Zyxel 24P) sitting next to it on the same router. If I just unplug my Desktop from the 1930 into the zyxel everything is quick again. If I move the cable down to the 1930 again the problem is there immediatly.
It's cloud managed mode and on Version 1.0.4 no errors and the desktop is not even in a VLAN it's just a plain native LAN.
No clue whats wrong.
It's not just a slight "felt difference" it is very standing out difference. On the Zyxel a big website loads in seconds. Same site on the 1930 takes 30-40 Seconds to complete because Each individual request takes ages.
Here are two Screenshots whre you see the huge difference of the same website, only thing I change was moving my cable from 1930 to zyxel:
