JSP & HTML validators performance [message #199136] Thu, 30 August 2007 07:29 Go to next message

Before trying to file a request enhancement, I would like to know your
opinion about the performance of the JSP and HTML validators.

We are developing a huge web application, with hundreds of JSPs and
HTMLs. When the project is built, after compilation the JSP and HTML
validators are started: there are 3 or 4 of them that start together, in
multithreading. On my PC (Sempron 2600+, Windows 2000), the validation
process takes minutes and minutes to complete... moreover, it seems that
the validation threads are eating almost all the CPU, slowing down the
other IDE operations, so they make it hard to continue to work. If I can
remember well, they are also blocking some other operations, so I can't
leave them in background all the time, but sooner or later I must wait
until they finish.
The only solution I could find is to stop or completely disable them.

The problem is not so evident on faster CPUs (like Pentium4), but the
CPU load problem is there too.

So, I would like to ask you if you have similar problems and, in particular:
- isn't there any way to speed up those validation processes?
- if not, is there a way to lower their priorities, so that they don't
slow down the other IDE processes?
- is it also possibile to make them not blocking other user operations
(like file saving)?

I'm using WTP 2.0 Europa release.

Thanks in advance for your answers.

I would have to agree. We make a project with lots of stuff in it, and
the validators do take quite a while to execute, especially if your system
isn't cutting edge.

Any discussion of priorities would have to be directed at the
validation framework itself, but it has been recognized that those
two validators are far too slow and require performance improvements
in the next release. See bugs 170640 and 170646 for progress on that.
