mod that I've created causes lag whenever activated.

[Misjudgments]

so, I've created a mod that sends a request to the hypixel api: api.hypixel.net
and i created a condition that on every 15 seconds worth of ticks it will send a request to fetch a certain data of all the players in the lobby
when it works, it causes a lag that freezes my minecraft client for about a second, then unfreezes the game and works perfectly until the next time it runs (after 15 seconds).

if anyone could help me understand why it is happening and how can i fix that i would be very grateful, thanks to all the readers and the responders.
(english is not my main language so if my post seems weird or offensive in any way please forgive me.)

accidently created this in support & bug reports instead of modder support.
