Hi Thiago, 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? image-compression=auto_glz 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! 2017-03-16 16:34 GMT+01:00 Thiago Nascimento Araujo <tara...@artit.com.br>: > Hi, > > I have been using, for quite a while, the following options for those who > connect through spice-html5 from outside: > > image-compression=auto_glz > streaming-video=off > playback-compression=off > jpeg-wan-compression=always > zlib-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.sega...@gmail.com> > *Para: *"Thiago Nascimento Araujo" <tara...@artit.com.br> > *Cc: *spice-devel@lists.freedesktop.org > *Enviadas: *Quinta-feira, 16 de março de 2017 6:12:05 > *Assunto: *Re: [Spice-devel] Spice optimization over WAN > > > Hi 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 <tara...@artit.com.br>: > >> Hi Oscar, >> >> I believe the documents is talking about the options described in the >> link below. >> >> https://people.freedesktop.org/~teuf/spice-doc/html/ch03.html >> >> Hope it helps. >> >> ------------------------------ >> *De: *"Oscar Segarra" <oscar.sega...@gmail.com> >> *Para: *spice-devel@lists.freedesktop.org >> *Enviadas: *Quarta-feira, 15 de março de 2017 14:04:14 >> *Assunto: *[Spice-devel] Spice optimization over WAN >> >> >> Hi, >> >> I have read quite slowly the datasheet published by redhat: >> >> https://www.redhat.com/en/files/resources/en-rhev-spice- >> protocol-11080057.pdf >> >> 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. >> >> _______________________________________________ >> Spice-devel mailing list >> Spice-devel@lists.freedesktop.org >> https://lists.freedesktop.org/mailman/listinfo/spice-devel >> >> > >
