Hi, I have a patch for the UI compression, it is on review for a while... But I hope I will be able to resolve the comments in...days.
I measured the download size dropped from 3.5 MB to somewhere around 0.5 MB https://reviews.apache.org/r/12228/ Adding javascript compression could also help a lot. That 3.5 M is a lot even on LAN :-) On Thu, Feb 13, 2014 at 7:04 PM, John Kinsella <j...@stratosec.co> wrote: > Just posted > http://theresnomon.co/2014/improving-cloudstack-ui-performance/ - open to > any comments. > > John > > On Feb 10, 2014, at 12:47 AM, Alex Hitchins <alex.hitch...@shapeblue.com > <mailto:alex.hitch...@shapeblue.com>> wrote: > > Sounds interesting, I look forward to your write-up. > > > > Regards > > Alex Hitchins > > D: +44 1892 523 587 | S: +44 20 3603 0540 | M: +44 7788 423 969 > > alex.hitch...@shapeblue.com<mailto:alex.hitch...@shapeblue.com> > > -----Original Message----- > From: John Kinsella [mailto:j...@stratosec.co] > Sent: 10 February 2014 01:05 > To: <dev@cloudstack.apache.org> > Subject: Re: UI Latency > > I've been tinkering with httpd proxying the UI via mod_proxy_ajp, then > using mod_deflate to compress on the httpd side.
