Hi
Quite often it can take 15 to 30 seconds to start to load a webpage or follow a link. Once the loading has starting, the whole page comes in instantly. Occasionally, there is no response and browser responds with cannot load webpage. A retry a few minutes later then works OK (although I might need to wait as above). I would say the slow response seems to be getting more frequent, which is why I am bringing it to your attention.
FYI at this end I clear cache, cookies etc. automatically every time browser is closed. No similar problems on other sites.
ps. just did preview before posting this and it took 25 seconds to give me the preview - typical example. (and another preview after this last sentence and it was instant)
