It was six times faster as an interpreter and twice as fast as a compiler than Lucid Common Lisp, which was the fastest at the time(1992), and in some benchmarks was faster than optimized C code on the same machine. It was named Tachyon Common Lisp (development code name) by the developers to mean faster than C (the speed of light in physics).[1][2]
Language Specification
CLtL2 compliant at the beginning of development, later made compliant with ANSI standards[3].
The OKIstation 7300 was also used as the initial operating platform, later ported to machines with SPARC and PA-RISC.
