Subject: Garbage collector tuning?
Date: Thu, 10 Sep 2015 07:46:57 +0100 (BST)	[thread overview]
Message-ID: <alpine.DEB.2.11.1509100733580.7865@wedemob> (raw)

Hi,
I wonder whether there is a more performant way to allocate larger memory 
blocks (e.g. 1 MByte). "gc-malloc-pointerless" seems to be much slower 
than "malloc":

                                            user     system      total        real
     Guile allocate memory              0.003780   0.000020   0.003800 (  0.003810)
     C allocate memory                  0.000060   0.000000   0.000060 (  0.000070)

Is there a way to control how often the garbage collector is run?

Thanks
Jan
