How is TSTO running for you? And what platform do you play on?

"Android: A lot more lag and/or crashing than usual, but still very playable"

This sums it up very well.

My gf is also on an Android and is experiencing the same thing.

I also play on several devices including a kindle fire, iPhone, iPad and android tablet. The game works best on the android tablet, next iPhone, then tablet followed by sluggish kindle.

It's not quite as smooth at times, and the occasional lockup. Playing on an Android tablet with KitKat and phone with Lollipop. It's at least not crashing like it did when the trash dumping started...

Android phone with Jelly Bean. I don't think I experienced any serious problems before monorail update, but now it sometimes freezes once a day and sometimes freezes 2 or 3 times every play session.
It usually happens in my town, when spawning possums or tapping buildings with several characters inside (like SH currency generators or recycling centers).
I have had no problems in getting all the event prizes, so the game is still playable, but if they don't fix this and keep adding new content it'll be unplayable at some point.

I play on iOS and at the moment have had no performance issues http://static.skaip.org/img/emoticons/v2/ffffff/fingerscrossed.gif

Playing on Android using 2 different devices a Galaxy tab 3 10.1 and a Galaxy S5 I'm getting a little more lag on the tab 3 especially if all my character are roaming around and the monorail is running as well but clears up after a few seconds, also get the odd Bart screen especially if doing the neighbours round but I don't seem to be having as much trouble with the game as some people are saying.

I play on two Android devices:

-Galaxy S4- Runs slow, and the items keep having to reload frequently. However, this almost never crashes.

-Galaxy Tab 3 7.0- Runs pretty smoothly with a little lag here and there, and it sometimes crashes.

I play on an iPad Air or iPhone 6 and I rarely Have performance issues...and I even have a second monorail set up in my heights

I've had enough issues on Android I'm in the market for (yet another) tablet. I'll be reading this thread carefully.

iPhone 5 with a bit of a lag (I already voted, but forgot to comment)
