a few years ago i used to use a command that upped the amount of servers i could ping at once to get the server listings quicker.. can anyone rememeber the command to do this again?

In this few years, LFS is updated as hell. Maybe the code is removed - im not sure. I dont know the code, but still. And why would u need that? Waiting few seconds more is that bad?

pinging 900 servers takes a while.. used to take 15-20 seconds at most, without the command takes a 2-3 mins..

thats more than a few seconds difference

LFS automatically parallel pings now, rather than waiting for each response before sending the next ping, like it used to back in 0.3x days. There's just that many more servers now that, without any filters on, it takes as long as it used to.
