Bear in mind that when retrieving a custom property, the engine has to look
up whether there is a getProp handler for it. Locking messages should give
you an improvement.

The main difference between arrays and chunks is that arrays will continue
to access huge data sets in linear time, whereas chunks (depending on
exactly what you're doing) will slow down as the data set gets larger.

Kind regards,
