Mike Jumper commented on GUACAMOLE-377:
---------------------------------------
Resolved! For future reference/testing, here's the script I've been using to
generate load:
{code:bash}
#!/bin/bash
#
# spin.sh - Induces 100% CPU load on all processors. Mysteriously helpful for
# reproducing the graphical artifacts that occur with the scroll detection from
# GUACAMOLE-377.
#
# Ensure all child jobs are killed upon exit
trap 'kill $(jobs -pr) 2> /dev/null' SIGINT SIGTERM EXIT
# Occupy all processors using "yes"
for N in $(seq 1 $(nproc)); do
yes > /dev/null &
done
# Show current processor status, implicitly kill all "yes" processes started by
# this script once htop exits
htop
{code}
> Improve efficiency of streaming complex/large changes (Graphics Pipeline
> Extension, RemoteFX)

> Guacamole currently lacks support for RemoteFX, although the library
> leveraged for low-level RDP support (FreeRDP) does have this support.
> RemoteFX is important when it comes to forwarding accelerated graphics over
> RDP, and the same support should be added to Guacamole.
> Lacking API documentation for FreeRDP, this will naturally involve walking
> through the source of FreeRDP's own client implementation to determine what
> needs to be called and how.
