I've been doing a number of similar measurements, and have come to the
same conclusion. R is currently very conservative about memory usage,
and this leads to unnecessarily poor performance on

Hi All,
This is a very important issue. It would be very sad to leave most users
unaware of a free speedup of this size. These options don't appear in the
R --help output. They really should be added there. Additionally, if the
garbage collector is working very hard, might it emit a note about better
setting for these variables?
It's not really my place to comment on design philosophy,

Just wanted to start a discussion on whether R could ship with more
appropriate GC parameters. Right now, loading the recommended package
Matrix leads to:

Ncells 1076796 57.6 1368491 73.1 1198505 64.1

Results may vary, but here R needed 64MB of N cells and 15MB
