Hi, A 800K HTML file over a 56K modem on a good line will take about 170 seconds to download. If you have been clever and separated out the javascript as static files and included them in the main page the browser can cache you may improve on this for subsequent round trips to the pages that use these javascripts.
It sounds like it is mostly data that makes up the volume. I'd be thinking about having data paging build into your screens, i.e. only show the first 20-50 records for a screen with a button to fetch more if desired. Or using a filter with a default value to restrict the number of records shown. Bear in mind that most government departments here in the U.K. and in Australia consider 10 seconds a maximum download time for a HTML screen over a 56K dial up connection, about 11KB page size.

I was wondering if anyone has yet to hit any walls and at what point would I need to consider moving to a wizard type of input, breaking the entry point into multiple screens to reduce the single impact of loading all this data into one screen class. I've tested this large screen with both IE 6 and Mozilla 6 and both seem more than capable of handling it. I guess the real limitation is the clients physical ram and if you can wait long enough for the browser to parse such big files. even at this point of 12000 lines in one page, it only takes about 2 seconds to load running turbine off of an old PII with linux and 128 meg of ram and the client is roughly the same... i have only tested with about 10 users simultaneously and doesn't seem to affect performance noticeably at this point. your thoughts are appreciated and hearing other users experiences is always a Good Thing :) cheers, Jeff Painter [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
