Ticket #23138 – Description
initial v3 1 As described in https://groups.google.com/forum/#!topic/sagedevel/jN6inWPyElM, `assume()` takes more and more time the bigger the `assumptions()` data base is. This causes a lot of slowdowns when e.g. declaring variables with a `domain` argument. Nils Bruin suggested that this is due to excessive interactions with the Maxima library and Ralf Ste fan suggested that the assumptions could be cached and only sent to Maxima when needed, to speed up the process.1 As described in https://groups.google.com/forum/#!topic/sagedevel/jN6inWPyElM, `assume()` takes more and more time the bigger the `assumptions()` data base is.
