Sounds great.

A 386SX16 is pretty slow doing just about anything.
Time to invest in new computer.
You can get P166MMX w/32 meg and 3.0gig for under $1000.00.
A modern computer would probably run 10-20 times faster.

If you run it on MSWLogo you can use some of the precise timing
procedures to find the hot spots. I'd love to add a performance
profiler some day (tells you where your spending all your time).
The 32bit version also makes better use of the CPU.

In most compilers breaking out common sub expressions don't
help because the compiler does it for you. But in Logo it helps
a lot.
