[Zope] Performance boost

[Robert Leftwich]

Note that the default installation (at least on NT) has the -D switch in
the start.bat, so if you use external DTML files extensively (via
HTMLFile) then a fairly significant performance boost can be gained by
removing the -D option.

PS Thanks for the info - as it turned out, I decided to do my basic
version checking on product startup by reading each DTML file and
extracting the version string which is embedded as a comment on the
first line of each file. This eliminates the problem in my original
implementation where the file is version checked every time the DTML
code is run, which is an unnecessary performance hit.
I was very surprised at how quickly the code ran, it takes less than 1
second on my dual PII-350 NT machine to open each file, read the first
line, break the line into the required pieces, call the version check
function and close the file for each of the 146 dtml files that I am
currently using !

PPS Out of interest, is there a way for the name of the HTMLFile object
to be accessed in the actual dtml code in that file without knowing the
variable name to which it is assigned ? Otherwise, you have a potential
maintenance problem with having to change the name in the .py and the
.dtml files if you want to rename the variable.
