I'm using a MBA 2012, i5, 128SSD, with ML 10.8.1 After a couple of windows decades, must say this is some great piece of machinery. Everything is blazing fast, except for one little thing: - Opening a subfolder (in list view) that has many files (more that 2.000 web images) isn't instant - it lags about 2 seconds. Is this normal? - Opening any subfolder in the documents folder (even one with few files) also lags about 2 seconds My documents folder is huge - 10 GB - more than 82.000 elements! Is this lag normal or should I do some optimization (only the document folder has this lag)? Moving less frequently used files/folder in another folder might help?
