I am surprised the wording.
The command will encode all y4m files in the directory at 200 kbps up to 500 kbps at a 50 kbps increment. Encoding only uses one core, my machine is powered by AMD FX8350 processor, and you can see encoding is currently very slow well under 0.5 fps for a CIF video (352 x 288 resolution), but that should be expected because VP9 encoding is already slow (its successor is expected to require even more processing power), and first software implementations are usually not optimized for speed, they are just meant to show the encoding works.

Reference encoders are
always super-slow*. The official reference implementations for H.264 and HEVC are about 100th the speed of x264 and x265 and lack lots of critical features. All the SIMD and multithreading work goes into production implementations.
* The one exception being VC-1, since that was actually done from the WMV9 decoder porting kit, and thus accidentally was full of real-world features and optimizations
