Hello Dirk,

I tested this SCons version with memory optimizations on 10000 C++ files.
Updated graphs can be found here: https://github.com/aqualid/aqualid/wiki/Benchmark-results-for-v0.5

I see about 20% improvement.

As I understand using posix_spawn function should improve performance on Linux and OSX.

Best regards,
Constantine.

As a follow-up of these investigations I have prepared a patch that switches SCons (especially the Node class) to using slots, in order to reduce the overall memory consumption. If you're interested in trying it out with your benchmark, you can get a copy with

hg clone http://bitbucket.org/dirkbaechle/scons_experimental -r switch_node_to_slots
