The server was not running at perfect FPS. var is(in lamense terms, as i understand it) the deviation from the average fps, this shows a var of 19, when this should not go over 7-8 for a normally operating server.
The snapshot is low because the server was hopping between single digit FPS and the normal fps, why it got captured at 15 instead of the other fps rates, i have no idea.
We run our sv_maxcmdrate and sv_maxupdaterates at 34.
Our net_splitpacket_maxrate is set quite high, but to my understanding, it will compress the data that it is currently sending out, meaning there will be no difference if it is set to 500,000, or 800,000(ours isn't that high), because the engine could never send that much data.
We cannot use the default settings, if we did our server would be unplayable(specifically using sv_parallel_sendsnapshot set to 0).
Notice in the red box, that is what we see when we experience the lag, the server fps hits single digits at the same time as those red triangles pop up(if you go into a server and shut it down, you will see this but as a solid line, not triangles)
Our current rates are this:
sv_minrate 75000
sv_maxrate 0
net_splitpacket_maxrate 201000
sv_maxupdaterate 34
sv_minupdaterate 33
sv_maxcmdrate 34
sv_mincmdrate 33
sv_parallel_sendsnapshot 1
sv_parallel_packentities 1
sv_max_queries_sec_global 3000
