Luke Campagnola	9a1d7d74cb	Improved performance for remote plotting: ... - reduced cost of transferring arrays between processes (pickle is too slow) - avoid unnecessary synchronous calls Added RemoteSpeedTest example	2013-01-10 16:10:27 -05:00
Luke Campagnola	8355e6148d	Performance improvements: ... - AxisItem shows 2 tick levels instead of 3 - Lots of boundingRect and dataBounds caching (improves ViewBox auto-range performance, especially with multiple plots) - GraphicsScene avoids testing for hover intersections with non-hoverable items (much less slowdown when moving mouse over plots) These are deep changes; need good testing before we release them.	2013-01-09 22:21:32 -05:00
