No idea why unlagged is set to off, or even if it is at the moment. I'm pretty carefree with my server. There are a number of members with the ability to turn unlagged on/off and they do so at their desire. I should make an admin command so all MG members can change it. Soon as I get off my lazy ass I will

There are a number of reasons why the ping is set high. Or I should say, why I never changed it from the default. When I set it up there were only 20-30 servers (I think around there) and getting a server with really good ping wasn't always that easy. Back then when someone with 150-200 ping joined it was typically cause there wasn't a match going on on servers that had good ping for them, so you delt with the warping and whatnot and still had lots of fun.
MG also has European members, so allowing them to visit, if only to build or chat if it was too laggy for them to play was a big plus.
Also, before you found beta maps running on every server, I had Beta Map Fest. A weekend when the server went all Beta maps. At the time, the DB servers where the only beta servers and they were in Europe so people on my side of the pond (US) had no real options to try a real match on beta maps except gloomb1 (I think that's it, it was in rotation on AKKA) and derelict on occasion. I wanted everyone to be able to visit, including the mappers (many of whom are European) regardless of ping so they could watch the fun if they wanted to.
Also, for a few months I had a large Polish contingent that played almost nightly and though their pings were quite high, they seemed to have a lot of fun. I didn't want to block them from accessing the server so I didn't lower the ping then either.
Aside from that, a lot of my regulars had very low ping, and a server operator didn't have to worry about people with all sorts of ping warping around a server

I guess it's just never been a problem that I needed to fix.
Incidently, I have a problem with map changes where the map just hangs for about 30 seconds. Not every map, but some. People complain "lag!" but I know that that isn't the case. I suspect it may have to do with !layout, but I haven't investigated in any great detail. I'm using Risujin's build which is different from yours. I suspect layout though it could be a configuration issue. I have added/subtracted cvars at a dizzying rate at times as I move to different builds.
