On Friday, @adept and I launched SteemPixels.com, a collaborative drawing app based on the Steem blockchain. If you haven't checked it out, hop over to the announcement thread and read about it.
Since launch, we have gotten 15,000 pixel updates drawn on the canvas and now looks like this at the time of writing.
Behind that image is the Steemit comment thread that is the database for all the pixels. The thread at this time has over 15,000 comments which does a number on the browser. Here is the loading when visiting the Database Thread which may crash your browser.
Loading this up on a 2015 MacBook Pro in Google Chrome with an i7 processor 16GB RAM is pretty memory intensive. The full load took nearly 2 minutes before the content and the avatar images appeared. The thread in Chrome for the tab reached 3.5 GB of memory as well.
Yeah, I noticed this yesterday. There needs to be some mechanism in the steem API to handle huge comment threads better.
