default min-v/nsize parameters
...ch the current numbers are optimal. The current minimum size
increases for node and vector heaps are 40KB and 80KB respectively.
This grows as the heap grows (min + .05 * heap), but still means that
we do many more expensive garbage collections at while growing than we
need to. Paradoxically, the SMALL_MEMORY compile option (which is
suggestd for computers with up to 32MB of RAM) has slightly larger at
50KB and 100KB.
I think we'd get significant benefit for most users by being less
conservative about memory consumption. The exact sizes should be
discussed, but with RAM costing about $10/GB it d...

default min-v/nsize parameters
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:
> library(Matrix)
> gc()
used (Mb) gc trigger (Mb) max used (Mb)
Ncells 1076796 57.6 1368491 73.1 1198505 64.1
Vcells 1671329 12.8 2685683 20.5 1932418 14.8
Results may vary, but here R needed 64MB of N cells and 15MB
