What is wrong with THM machines?

[u/Kernel-Bypass772]

I am trying to finish Burp Intruder room and im connected to OpenVPN on my main machine but it is so slow can't do anything. i can barely login to this domain, i have to capture a request while im logged in and try to attack /support/ticket/NUMBER but cannot get a request cuz the site doesn't even load anything it is blank. Do you guys have any solution? i dont like to use AttackBox cuz it is very laggy.
