Important: #92356 - DataHandler performance improvements¶
DataHandler is the central backend heart of the system to
persist state changes in the database whenever editors change elements.
Some changes have been applied to reduce the database query load performed
DataHandler and its related classes. Latest changes especially
dropped a number of useless queries and php operations when relations are handled.
Depending on the handled structure, the
DataHandler executes up to 30% less
queries than before. More improvements continue to happen and will be ported
to v10 if possible.
