Changeset: bb56535aa6df for MonetDB
URL: http://dev.monetdb.org/hg/MonetDB?cmd=changeset;node=bb56535aa6df
Modified Files:
gdk/gdk_utils.mx
Branch: Dec2011
Log Message:
GDKinit: set GDK_mmap_minsize & GDK_mem_bigsize to 1 GB
With available RAM sizes growing,
GDK_mmap_minsize = GDK_mem_bigsize = 256 MB
appeared to be on the small side.
We now set GDK_mmap_minsize = GDK_mem_bigsize to 1 GB,
or ~80% of the available memory (i.e., GDK_mem_maxsize_max),
in case the latter is smaller.
