Hi Thiago,
image-compression=auto_glz
streaming-video=off
playback-compression=off
jpeg-wan-compression=always
zlib-glz-wan-compression=always
Can you explain to me what is their specific function?
Thanks a lot for your help!
In my scenario, I'd like to connect to the spice server over WAN but using remote-viewer (nor the html5 client).
In this case, this convination of parameters, is good as well?
streaming-video=off
playback-compression=off
jpeg-wan-compression=always
zlib-glz-wan-compression=always
I also liked to ask for theese parameters:
- streaming-video=<all|filter|off> Set video streams detection and (lossy) compression (default=filter)
- playback-compression=<on|off> Set playback compression, using the CELT algorithm (default=on)
Can you explain to me what is their specific function?
Thanks a lot for your help!

Hi,I have been using, for quite a while, the following options for those who connect through spice-html5 from outside:image-compression=auto_glzstreaming-video=offplayback-compression=offjpeg-wan-compression=alwayszlib-glz-wan-compression=always Since I keep everything up to date: kernel + qemu + spicelibs + spice-guest-tools, maybe those options are no longer necessary.For people who connects through lan or mpls, I leave the spice server on default settings.Note that compression options generates overhead on the server.Since I have a very small number of external users (Those are for VDI non-persistent), and all of them are simple remoteApps, the overhead is ok.Usually the spice (default settings) + qxl + spice-guest-tools + virtIO are the best combo.The default settings optimizes based on some bandwidth calculations and enables or disables some of those options.De: "Oscar Segarra" <oscar.segarra@xxxxxxxxx>

Assunto: Re: Spice optimization over WANHi Thiago,Thanks a lot for the useful link...Can you/anybody tell us the suggested configuration/parameters for best performans over WAN?Thanks a lot.2017-03-16 0:07 GMT+01:00 Thiago Nascimento Araujo <taraujo@xxxxxxxxxxxx>:Hi Oscar,I believe the documents is talking about the options described in the link below.Hope it helps.De: "Oscar Segarra" <oscar.segarra@xxxxxxxxx>

Assunto: Spice optimization over WAN______________________________Hi,I have read quite slowly the datasheet published by redhat:Where one can read:"In addition, SPICE has WAN optimization capabilities optimize the user experience for lower bandwidth and/or higher latency network connections"Anybody knows where can I find documentation about this optimization capabilities for lower bandwith and high latency networks?Thanks a lot._________________
