Hi guys,

being back after long time,currently I am exploring the optimization of loading resources of zkoss.I have tried everything and managed to minimize the requests for
a simple entry login page from 15 -> 6 optimal but set back to 9 which is already something.But I am very disappointed and currently I am thinking dropping out of the
framework because according to firebug and chrome...the response time is downgraded because the zk.wcs and zk.wpd take 5 secs of the 7 to load the first simple
login form web page.I could attach and image if would be possible but it's not.My thought now is to go back to pur HTML5 and bootstrap configuration for the ui, since
nowadays they offer most of the components we would like to use.Does the devel team have any thoughts on optimizing that.On the other hand I am planing on deploying the project on a more "powerfull" machine...with i5 cpus...but that's not the answer a dual core Intel Core2Duo should be sufficient to do stuff.Any thoughts
on that aspect?

You may not have had answers because you might need to provide a bit more information. Tuning and/or performance monitoring is as much an art as a science but as a start, the more information the better.

Are you ZK 3, 5 or 6? Response times local or remote? Network speed? Test PC/Laptop model/speed etc. Server Speed etc.

But having said all the above, we get response times of well under a second for a simple logon screen on a local network using not particularly state of the art hardware.

So I am very very surprised at your 5 seconds just for loading zk.wcs and zk.wpd. To me there seems to be something seriously wrong. Are you using Tomcat? Has it enough memory? We don't get that sort of bad response remotely over ADSL either.

I agree with Bobzk. Five second load time definitely tells us that something is very wrong.
My production app loads zk.wcs and zk.wpd in under 300 ms on a good internet connection, and the browser will cache those files which will further reduce the page load latency.
