Thank you, bsdfish! I was able to increase CPU utilization from ~25% to ~70% without making any changes other than tweaking the gc settings as you suggested. I hadn't even suspected that the gc would be running frequently enough to have that sort of impact, so I likely would have been on the wrong t...

It looks like you were all either entirely correct or at least had the right idea. I was using top to monitor the CPU usage and it turns out that I couldn't tell the difference between using 25% each of 4 cores and using all of one. I'm obviously hitting some other kind of bottleneck, but I'm not su...
