Pages are opening very difficult. For example macrumors.com is opening in 3-4 seconds in WINDOWS XP via PARALLELS and in LEOPARD 10.5.5 in more than 30 seconds(FIREFOX,SAFARI,OPERA). I'm using ADSL internet. This trouble appeared 3 months ago. Untill then everything was allright with internet in LEOPARD. Can anyone help me? Thanks.
