FWIW, I tried the same regex in Tcl. Using tclsh, I entered at the
prompt:
% regexp -inline {[a-z][a-z0-9\\-_.]{0,20}}
a012345678901234567890123456789
a01234567890123456789
It seemed to work fast, but to quantify execution time, the timed
output of 10 iterations was 1.3823 microseconds

Changing the {0,20} to + makes it run normally fast so I just replaced the
regex with a string-length and
