Re: Internet access speed. I use a 56K modem to access the internet via several different services & have noticed that at the same baud rate, I get very different performance from various connections. The company I work for recently contracted with IBM Global networks for remote access to their intra-net via the web and I noticed that the performance is noticeably better than when I dialed in directly to the company which has a T1 connection to the web from Pacific Bell (even late at night when I had the T1 mostly to myself). The company connection is only marginally better than my local ISP (a very good one). A connection to a friend's MSnetworks account was just plain horrible. All this at the same baud rate! I'm still trying to figure out what all this means as to where is the congestion. The extremely good service from IBM has me suspecting that very often a slow downloading page may be the fault of the servers at the other end, not the speed of connection. Certain sites are slow responding, but once it starts to load the page appears in a flash. Other, hard to describe differences in performance could be the fault of delays at the back-bone (I believe IBM has its own). The very bad service from MSnetworks tells me that inadequate resources at the ISP can also significantly limit performance. One conclusion I am sure of. If the apparent server delays & backbone delays are factored out, the performance of a 56K connection is quite snappy and more than adequate for most web surfing uses other than bandwidth hogs like video or downloading very large documents like big bit-mapped color images or Windows applications programs. -Thomas
