lag

Hey guys, I'm looking for a good alternative to Bluestacks to run multiple/mass dating profiles on. Bluestacks is very slow, lags a lot and crashes. I was wondering if anyone knows a better system for this?

We are looking to cause massive client/browser lag by spammer a certain type of text on Discord IRC...Zalgo text works for the client, we need something spammable that will cause massive lag on a browser.
