Just as an experiment, I compiled an old grep utility using both GCC and TenDRA. The results were really disappointing. :-( The TenDRA-compiled utility runs around twice as slowly: gcc 5.74 real 5.69 user 0.04 sys tcc 10.64 real 10.48 user 0.07 sys >From a 233 MHz PII running -current searching on /usr/share/dict/web2.
