In order to get the best performance out of the system, the most important aspects to consider are (in descending order):
For the vast majority of cases, the defaults should already be optimal.
Please see Automated performance and regression testing
Below are some more advanced performance related topics:
To be able to use a single client to create many connections to many servers, or simply to simulate an extremely high performance client, r2482 adds the ability to skip the client code which normally paints the windows. To use it:
XPRA_USE_FAKE_BACKING=1 xpra attach
XPRA_FAKE_BACKING_DELAY can be used to control how long (in milliseconds) the client waits before responding to the server after each draw packet:
XPRA_FAKE_BACKING_DELAY=10 XPRA_USE_FAKE_BACKING=1 xpra attach
Note: the windows are still shown - just not painted.
Tuning / Pending items
The following mostly undocumented tunables can have an impact on performance and should be investigated more thoroughly under different scenarios:
XPRA_YIELD- see #181
- Video compression options:
XPRA_SCROLL_MIN_PERCENT, etc.. refer to the source code for details.
