Validation user input VS Javascript

[betterdie]

Hi all;

I code Perl for CGI, I using regular expression to check the validation
of user input, because the form is small and it run only from my own
computer, anyways if many people using my form, do you think it will be
slow due to Perl is run under server. How about using JavaSCript to
check validation for user input? Do you think it a bit faster?

Thank very much

If you are posting back to the server everytime you validate this field then
yes - it will be much slower than validating it using Javascript (or
VBScript) as that runs on the client.
