There has been a lot of discussion about lag recently, with many people blaming the servers. Allow me to quote a chat that I found with chip. For those who do not remember/know, chip was an intern at Cyan, and he was ultimately the one who worked on the Untìl Uru servers and released them to the public.
<chip> oh man, can we please start arguing about plasma again
<chip> the problemm isn’t plasma2.0 or the plNetCore
<chip> its the fucking physics crap
<chip> it was sloooow
<chip> you put like 30 people on the same screen
<chip> it just goes to all shit
<chip> * same area
<chip> I learned lots at cyan. mostly that you can optimize the backend servers all you want
<chip> but in the end
<chip> a shitty client (in this case in c++ and python)
<chip> can still make the whole thing suck
So there you have it, the servers are not the problem. There were a number of improvements during MOUL (including removing the cones entirely), but for lag to disappear entirely will be a client-side issue and has nothing to do with the servers.
