So the lag that my server is suffering from only seems to happen after it reaches a certain amount of players. The lag happens more frequently when there are around 10 players.
Here is a gif I made of what net_graph 5 looks like during the lag, I slowed it down so it's easier to see:



The lag never happens constantly, it goes off and comes back randomly, but the lag happens more frequently depending on the amount of players usually.
The more players there are, the more frequently the server starts to lag.

This is what the SolusVM Control Panel statistics say about the server in a 1 day time span:


What could be the issue? I hope this isn't a problem with the host bandwidth, because if it is then how am I supposed to fix it?
I have already tried increasing the sv_maxrate to a higher value and fps_max to 600, but it didn't improve anything at all.
Help is much appreciated, thanks in advance.

You have a lot of plugins loaded on your server, so this may be one of the reasons to the lag.

[GreenGiantJr]

Sadly there is no easy way for me to check if the plugins are causing the lag, because first I need around 10 players on the server to see if anything has changed, and getting many players to join is quite difficult. I also don't personally think it's the plugins fault. I have seen servers with way more plugins, with similar plugins in fact, and they don't have the same lag as my server. If those servers lag, they suffer from either choke or higher pings, which my server doesn't seem to get.

Couldn't the issue be the outgoing bandwidth? I don't know why the bandwidth is only giving out a max of 101.9kB, if I try to upload a 100MB file for an example and download it from the server then it downloads the entire file in the matter of seconds with my 100mbit/s connection, so why is SRCDS only giving out so little?

EDIT: I had 9 players on my server and decided to turn on War Mode in Sourcemod (it disables all plugins), but the server was still lagging a bit. So from the looks of it, the plugins are not to blame here.

Are your VPS hosted by a company? If it is, then just call/write to their support, in this case it seems like the best idea.

[GreenGiantJr]

They're hosted by a company, yes. I'm not sure what I am supposed to ask them since they don't deal with SRCDS or gamehosting, but I'll try to ask them about my low bandwidth output and ask if that's normal.

[SuzmA^]

At least they may have some experience with this..
