Dan, I have only my own experience to go on. When things are real slow loading this is reflected in the IE bar info, when it it reports high figures, this goes with pages loading well and reasonably quickly. When it reports medium figures this goes with medium load times. A real bad trip eh, mate? I have been - obviously unsuccessfully - trying to stress a really practical measure, that is how much on average comes down in what time and not unduly worry about rather technical information that bears on this in complex and mostly misunderstood ways. A stopwatch is the most accurate way to do it, but looking at the IE bar or equivalent will do a rough job. If folk don't want to look at the figures in either this rough way or in the most perfect way (the stop watch and knowing the size of the download) then yes there are doubtless all sorts of other fancy stuff that can be used (and to possibly confuse further). >> Now, in a modern city, it is rare for anyone to get much more than 5K/sec and >> certainly not for long. >> > City has nothing to do with it. > City has nothing to do with what? The infrastructure in Australian coastal cities, at least in Sydney, has had a big boom in recent years, the bush (the countryside, inland, including nearlyNowhere) is fighting to catch up and there are a lot of very old unreliable lines and telephone equipment. This makes a difference. We have all agreed on the importance of clean lines. In many contexts, City has a lot to do with "it" simply because governments and companies pour money where there are more votes, and cities have more voters. Tell you what, mate, I concede this: City may not have much to do with some highfaluting figures like vThis or vThat or baudBitStreamSomethingElse or whatever. > A decent V.90 connection is a RAW 4 to 5 KB/sec.

And not to spend so much that the declining price of ADSL does not become a reasonable alternative. This V.42 business, we talking the need to get different modems here? For eBay pages to load faster etc etc. I use FreePPP and a modem called SimpleModem (on a 7600) which is supposed to be 56K. There is a red flash on which 56 is imprinted (the flash is a sort of lightening bolt logo that one often sees on the tight teehirt under the cape or whatver when a superhero flies past...). I also use a fancier more modern-looking sexier (because see-thru plastic I guess) MacSurfer V90 56K with Remote Access on a 7300 and still get the same old slow 56K results... David Elmo PS. Practical advice: those who have a lot to do on their computers, do some of it while pages load in the background. Have a few things going at once and it is less frustrating. Eg. when checking out Ebay, open up several items in new windows (make them small, up in the corner) and they load up while you are browsing the list of auctions... No offence to those who already do this. It is a habit that is not always acquired even tho it may seem obvious. -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
