Once the number of swap files exceeds five or so, your Mac starts to slow down. However, if you are looking merely for entertainment and some facebook browsing, StgrongVPN can be technically complicated to deal with and I would recommend other more user-friendly free services. Safari, Firefox and iTunes all allow you to clear caches directly within the apps. I am looking for a solution and hope to find one soon :) So I would recommend StrongVPN if you are looking for a powerful service and need to use VPN extensively such as for work purposes. After having used my account for three weeks the VPN suddenly stopped connecting yesterday onward. Moreover the user interface is forever improving. However, the instructions and FAQs are quite helpful now. So as you open more tabs Firefox slows down. As you open more tabs a small part from this allocation gets allocated to your new tab.
It allocates a big chunk of memory to the application. Firefox uses the traditional method of memory management. We used to love the free live support that was available earlier. However if you use computers with less memory Chrome will keep crashing as it runs out of memory.
It is powerful with reasonable speed in China (even better speed in Europe where I stayed for a short while). In general we have both been satisfied with StorngVPN's services. Earlier I used to use my husband's account but it speaks for them when I say that I chose to open an account of my own as well. I have been a customer of StrongVPN for about 4 years now and have seen them balloon from what they used to be.
