How to stop lag.

Lag is something me,and alot of players hate. There is not alot of ways to stop lag,as its because AJ Is powered by Adobe Flash Player,which can make games runned on it very slow,sometimes its because the jammer's Computer is old,it can also be caused by the computer's RAM. I have found out some ways to prevent lag,but they don't stop it complety.
1.Don't play adventures
Adventures cause alot of lag for some reason,my guess is because adventures have phantoms,chomper plants and the background scene. This may be hard for some jammers.
2.Don't use arrow keys.
I know this varies by computers,but for me making my animal walk with my cursor makes my game faster.
3.Don't use den claw machines. These things make dens really laggy,so i dont recommend to place them in your den.
