As part of a general overhaul of the editor in prep for Ajax I've been looking at how much stuff it is sending down/receiving over the wire - especially for big metadata records such as can result from iso19139. Its actually quite a lot especially with some naive drop down list handling (eg. for region lists - which we could cache in the browser cache without much difficulty). Adding a gzip servlet filter via the web.xml file can save quite a lot of waiting time for users and speed up editor refreshes.
I've also been using the yslow add-on to firebug and following some of its advice re: duplicate scripts, expiry headers etc - doing the expiry header and being selective about what is gzipped by the filter does improve loading and reduce the overall time taken to load the editor (and other pages) in GN. I'll be putting this in the bluenet mest tool for testing.
Cheers,
Simon
Hi Simon,
That's great work! Really hope you get around to also put that on the trunk shortly!
Ciao,
