RES: [struts] Re: [OT] Compression Filter
Hi Niall,
Did you measure the ration between "processor overhead (to compress) x
bandwith gains"? I'd like to have an idea if it would be good in general...

I've used the compression filter that comes with the Tomcat examples and
works fine with struts:

Re: [struts] Re: [OT] Compression Filter
Posted by Niall Pemberton <ni...@blueyonder.co.uk>.
Firstly I have to say we haven't yet deployed it yet. I did dig into it to
try and find if I could output some statistics on how much bandwidth the
compression was saving, but I got lost and gave up ;-) We have a number of
sites who don't have great connections and testing with them the improvement
in speed of pages was big. Processor overhead isn't something I really have
to worry about with the nunber of users on my system. We are defintely going
to deploy it though.
There is a threshold parameter you set (compressionThreshold), which is the
number of bytes (I think minimum is 128) - below which it doesn't compress,
we currently have it set to 512 - so if your worried about processor
overhead you can play with that so that its only larger pages which get
compressed.
