Safari is very slow only with one user

Hi all !

Nice to be here !

I need your help, I tried many things but the issue is still here and it's very annoying !

Safari is very slow for opening some specific pages. For exemple, the vimeo's players take something like 1 minute to show (but the rest of the page is downloaded quickly). This is only with my (OSX) user profile. When I log with the guest user or my girlfriend user, it's OK, safari is running fast.

- I reseted all Safari

- I chenged DNS

- I disabled the auto fetching DNS / Re- enlabe

- I Repaired my hard disk

- I re-installed OSX

- Deleted many files stored in the safari's library etc. etc.

What do you think I can try ?

Thanks a lot !

Have a nice week to all !
