I'm one of the admins at  http://forum.openscad.org/

When I attempt to post either a reply or a new topic I get:

The preview message works, but the post doesn't.

Connect to what?

However threads (8) were getting ~5% each for most of the peak shown here, ~50% total CPU.

I'm about to do performance comparisons.
I'm still working thru it, but I'm now leaning toward these lower CPU% threads are micro-workloads, for want of a term, they finish before consuming much CPU. I'm still looking at the performance info, but close to 100% of threads record zero CPU (which I think means <0.0000001), only a handful record more (eg ~300/~50,000 2D, ~1,700/~50,000 3D). [small sample size, need more varied CSG workload, still working on it]

ATM 2D multi-threading is worse than single-threaded, some times up to 200% [elapsed]. Probably due to the above. Whether a more chunky thread/workload allocation would be better needs consideration, where thread overheads would be less.   user-agent=Mozilla/5.0 (Windows NT 6.1; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0 method=POST referer=http://forum.openscad.org/template/NamlServlet.jtp?macro=reply&node=21300
