I tired with W8 before W7 and Ubuntu,...
Mine is very slow in webrowsing, the reaction time is delayed and annoying surf on the Web....

I tried with Chrome,IE11,Firefox....The netbook cpu usage is only 26%, 1,6 GB ram usage of 6GB. (E350,250HDD,6gb ram)
-I have installed all drivers
-in the lenovo power management settings are hight
-cleaned the cache and temp file with TTempFile cleaner
-In os not run not necessary apps

I can only think of 2 explanations, either your cpu is too slow, or your HDD is under too much load.

When i bought , i choose this cpu base on the tests on the net, like this:

(on the page in middle are on table, the first is same cpu ...and this e350 results are not so bad ...but in use this too slow 🙁 )
