When the pound has opened for the majority of times since the update, it has had significantly worse lag. It takes longer to load any page on the website (in my experience) while the pound is open. There is also longer hang when you click a pet but it has been adopted.
I also had two errors today where I clicked to adopt a pet from the pound, it took a while to load, then it told me there was an error adopting that pet and to go back. The pet appeared as available and not taken, and it has happened on two seperate pets.
These last few days have been worse for the lag, though I am imagining with the Easter season that a lot more people have been online and it is taxing for the servers.
I like the pound update - I think it has broadly been a move in the right direction in regards to fairness for users, but the performance has seemed to suffer lately, at least on my account. Other sites are loading fine, so it is just CS.
Curious as to if anyone else is having the same problem.
