 Since this is an area that receives constant tuning and improvements, the most reliable source of current information is the code itself:
-* [/browser/trunk/src/xpra/server_source.py server_source.py]: this class is instantiated for each client connection. In particular:
-  * {{{GlobalPerformanceStatistics}}}: collects various statistics about this client's connection speed, the various work queues, etc. The {{{get_factors}}} method returns a guesstimate of how the batch delay should be adjusted for the given parameters ("target latency" and "pixel count")
+* [/browser/xpra/trunk/src/xpra/server/batch_config.py xpra/server/batch_config.py] stores the dynamically updated batch delay configuration data and also historical values and the last set of factors used to derive the delay
+* [/browser/xpra/trunk/src/xpra/server/source.py xpra/server/server_source.py]: a {{{ServerSource}}} is instantiated for each client connection.
   * {{{calculate_delay_thread}}} which runs at most 4 times a second to tune the batch delay, both the global default one ({{{default_batch_config}}} which is a {{{DamageBatchConfig}}}) and the one specific to each window (see below for details)
-* [/browser/trunk/src/xpra/window_source.py window_source.py]: this class is instantiated for each window and for each client, it deals with sending the window's pixels to the client. In particular:
-  * {{{DamageBatchConfig}}}: the structure which encapsulates all the configuration and historical values related to a batch delay.
-  * {{{WindowPerformanceStatistics}}}: per-window statistics: performance of the encoding/decoding, amount of frames and pixels in flight, etc. Again, the {{{get_factors}}} method rreturns a guesstimate of how the batch delay should ne agjusted for the given parameters ("pixel_count" and current "batch delay")
-* [/browser/trunk/src/xpra/batch_delay_calculator.py batch_delay_calculator.py]: this class is where we used the factors obtained by {{{get_factors}}} above to tune the various attributes.
+* [/browser/xpra/trunk/src/xpra/server/source_stats.py xpra/server/source_stats.py]: {{{GlobalPerformanceStatistics}}}: collects various statistics about this client's connection speed, the various work queues, etc. The {{{get_factors}}} method returns a guesstimate of how the batch delay should be adjusted for the given parameters ("target latency" and "pixel count")
+* [/browser/xpra/trunk/src/xpra/server/window_source.py window_source.py]: this class is instantiated for each window and for each client, it deals with sending the window's pixels to the client. In particular:
+* [/browser/xpra/trunk/src/xpra/server/window_stats.py xpra/server/window_stats.py]: {{{WindowPerformanceStatistics}}}: per-window statistics: performance of the encoding/decoding, amount of frames and pixels in flight, etc. Again, the {{{get_factors}}} method rreturns a guesstimate of how the batch delay should ne agjusted for the given parameters ("pixel_count" and current "batch delay")
+* [/browser/trunk/src/xpra/batch_delay_calculator.py batch_delay_calculator.py]: this class is where we use the factors obtained by {{{get_factors}}} above to tune the various attributes.
