Michael Jumper closed GUACAMOLE-668. ------------------------------------ Resolution: Won't Do > Preferring JPEG due to lower CPU usage - controlling guacd behaviour via some > kind of preferences > ------------------------------------------------------------------------------------------------- > > Key: GUACAMOLE-668 > URL: https://issues.apache.org/jira/browse/GUACAMOLE-668 > Project: Guacamole > Issue Type: Wish > Components: guacd > Reporter: Andrzej Dorobisz > Priority: Major > > In our HPC center, we observe that guacamole-server (guacd) is generating > quite high CPU-usage even if only one session is currently processed (it > reaches 100% when moving window back and forth). > We have tested that using JPEG instead of PNG in > "{{__guac_common_surface_flush_}}_" (_src/common/surface.c_) noticeably > decreases the CPU usage. When WebP is available it performs better than PNG > but still it's slower (in terms of CPU usage) than JPEG. > We believe that user running _guacd_ should be able to choose which format is > preferred - without recompilation. Our first idea was to use _guacd.conf_ for > passing such a preference, but we see that it is not so simple. We have to > store such a preference somewhere and then pass it to VNC client which is > calling {{__guac_common_surface_flush}} function. > ------- > What do you think about adding such an ability and what would be the best > approach to implement this? If you provide guidance, I can try to implement > it. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
