I literally used to limp through Elvenar, meaning - my computer's cache, Adobe Flashplayer and the Inno servers got clobbered individually, in tandem etc - often. It was awful. I had to logout of game, logoff and reboot the computer frequently. 2015 - Win 7 Pro, HP gaming pc.
Old school computer stuff ... buses (think city buses), cache (think fast food restaurants), CPU (city hall), libraries (libraries or stores) and everything else that makes up a "city", is how computer systems were originally designed (yes, wa-ay back to the 1970s-1980s and earlier).
Everything gets gridlocked at rush hour.
Technology is infinitely better today, but it's still human-made and thus, fallible.
Software, too. Yes, jndeed.
You either fix the problems yourself - good luck with that, seriously - or roll with it.
