[tclwebtest] Slowness processing forms

[Grzegorz A. H. <gr...@ef...>]

Hi.

With complex forms, the use of "field find" can increase the
execution time of the test unit from one or two seconds to over
20. The bottleneck is found in extract_forms_if_necessary around
line 2750, the second loop, which uses a regular expression to find
all the form fields once per form field.

Teorically a speedup could be gained by using libraries like expat
through a tcl binding. It's not critical for us at the moment,
but I wanted to point this out in case somebody else wondered why a
"field find" can slow down things a lot.
