[BioC] startup options

[Kasper Daniel Hansen]

When we load say IRanges, it takes a while.  I seem to recall it has
something to do with memory allocation or something, and that there is
(or used to be) a startup option to R where you could increase the
relevant memory and thereby decrease startup time (including loading
of "standard" packages).  I seem to recall Martin Morgan posting about
it.

Does this ring any bells?

Best,
Kasper
