Hi everyone, I'm wondering if Mountain Lion is going to bring back the speed that was known in Snow Leopard. Currently I'm using Lion and while I really like the new features in Lion, the preview app is very very slow. In Snow Leopard pdf's opened instantly (I really LOVED that), in Lion I always get a beachball and I have to wait 10 seconds or longer to get the pdf (or an image) opened. So, does anyone know if this issue is resolved in Mountain Lion? And what about general system performance? Does it match Snow Leopard in terms of speed?
