yes they do...
In some pages is is 20 records at a time (like any search engine returns the
1st page as 1 of 2,000,000)
Yes, this I expect to see.  And a 20 (or 50, or 100) records at a time,
this is efficient and effective.  5000 records on one page seems wrong, in
the general case.

In some I return the whole set in html, usually not more than a minute or 2
to load.
Why?  Why not provide a page at a time?  This seems wasteful.  I have my
google preferences set to return 100 at a shot, and I find that I will look
through 100, or even 200 links, but 5000?  No way.  And why wait two
minutes to see a screen.  On the iSeries, my customers expect sub-second
response.  Not multi minute response.

Also provide a link to save the whole set in a .csv file from the ifs. They
can use it in Excel.
Fine, I do this, too.  But I can still provide a link to all the data, yet
display one page at a time to the browser.
