I did some tests a while back, on a 600 MHz Pentium III computer. I made a 2" diameter circle in 10,000 line segments. With the default smoothing, it took 250 seconds to execute. With the smoothing parameter set with G64 P0.0005 (meaning an error tolerance of 0.0005" is acceptable) this program runs in 17 seconds. At that rate, it is doing 10,000 blocks in 17 seconds or 588 G-code blocks a second. That is with a fairly slow computer by today's standards, too! I think I later got it down to 13 seconds, or 769 blocks/sec. These tests were done on a true servo system using my PWM controller board and servo amps. So, there was no BASE_THREAD task in the system, and no step pulses anywhere.
I think if you need more than 1000 blocks/second, you need to examine how you are generating your G-code and see if it can be optimized. Assuming 0.001" vector segments, you could move at on inch/second while following any arbitrary curve that doesn't exceed your machine's acceleration limits.
