Why does my server show up on the Master List slow?

[Inelegant]

Hey guys!

I host Garry's Mod servers on VPS's such as Ramnode and I am wondering why the servers running on these platforms only show up on the Internet list in GMod after a really long delay.
Servers I have ran on Windows Azure's VM show up after only a few seconds. Both servers are at the same location with a 1Gigabit uplink so I am sure that is not the problem.
I have tried both OpenVM and KVM visualizations and neither of them helped.

This has impacted my community's playerbase heavily and I wish to resolve this issue ASAP.
Please, any help will be appreciated.

Make sure you have sv_region set to 255 in your server.cfg

Thanks for the reply, but that's not the solution. Weird thing is, the server from Windows Azure works-out-of-the-box without any modifications.

Having the EXACT same server files and configurations on the new host is having issues with the internet list.

It's because of the current server browser. It has some flaws, including some servers not showing up. There's really nothing you can do about it.

The default gmod browser is slow in general lol and like code_gs said some servers don't even show up. I think it may have something to do with the amount of servers running a gamemode because i've noticed that the gamemode with the most servers loads the most servers in the least amount of time

Did you check to see if you can see it in the legacy browser?
