Why do web scan take a long time?

Postby XavierD » Fri Mar 28, 2014 10:14 am

Morning all:

My web scans that look for a security-check pattern are taking a long time.

Do you know any reason for this?

Thanks

Hey XavierD. Hope you had a great weekend.

If you are scanning for a regular expression match, and the page has a large number of elements, the search process can be slow.

The eValid spidering engine uses the same regular expression analyzer that is part of the eValid functional testing capability.

The problem is, if you pick a hard-to-match regular expression and the page is big (lots of elements) you'll hit a performance well.

Here is a command that lets eValid find the sourceIndex of an object on a page using a search process based on Regular Expressions:

Here is a page that benchmarks the eValid IndexFindElementEx command that searches page DOMs for Regular Expressions:

Hope this helps.
