longer than 2 minutes.
Pages load slowly
The time required for pages to load depend upon the amount of information contained in the page,
the processing speed of your computer, the amount of RAM available in your computer, and the
method of connecting (Ethernet, Internet, or direct serial connection). We recommend a minimum
processor speed of 100 MHz, and minimum RAM of 40 MB.
If connecting over the Internet, then your modem speed and the amount of Internet traffic come
into play as well. The WebMaster modem is 33K baud, so if your PC’s modem is 33K baud or
higher, the numbers below should be valid, given light Internet traffic.
In general, this is what you should expect:
