File Optimisation

I have a calendar system that details the appointments for various departments in the company and am having problems with the sheers size of the html docs that are returned. One department insists that they nned to see all the users in one go (approx 110) and the calendars for 3 months. This causes an html doc being returned frm the server that is 3.5 meg. Whilst is takes the server 4 seconds to build and deliver this I was wondering if there is any way to speed things up and reduce the amount of network traffic. Would zipping the file b4 it is sent be a good (and easy) way to go ? Thanks in advance, Steve Brett Internal Development EMIS Ltd.
