Changeset: c3f7b42bd85e for MonetDB
URL: http://dev.monetdb.org/hg/MonetDB?cmd=changeset;node=c3f7b42bd85e
Modified Files:
gdk/gdk_system.mx
Branch: Mar2011
Log Message:
Significantly speed up startup of mserver.
I had moved the function MT_check_nr_cores from gdk_posix to
gdk_system. This function checks a symbol to see whether it can use
sysconf() to find out the number of cores. This symbol is defined in
a file which is included by unistd.h. The include for unistd.h in
gdk_posix contains a helpful comment: "sbrk on Solaris", so I didn't
think to copy the include to gdk_system. This meant that
MT_check_nr_cores calculated the number of cores the hard way, which
the optimizer in the compiler (when used) would optimize into
oblivion, but if you don't use the optimizer...
