The loading of such a template cost 16000ms :(
Hi, all. My template file is shown below, getTemplate() cost more than 16000ms to load it. I don't know what's wrong with it. This template is created automatically by another Velocity client class (I named it as TemplatePublisher), so it is too ugly and long. Who can tell me how to optimize this template to make the loading time shorter?
thanks a lot!

Re: The loading of such a template cost 16000ms :(
Posted by Byron Foster <by...@base2.cc>.
There is something definitely wrong with your setup, getTemplate()
should be much faster, even when the template hasn't been compiled
yet. I'm not sure what you mean by "This template is created
automatically by another Velocity client class".
The problem you are experiencing is NOT due to the below velocity
template, but is some issue with your implementation.
Without knowing what you are doing it is hard to judge, but I suggest
you begin with the simplest possible code to load the below template,
and then work backward to find out where the problem lies.

Re: The loading of such a template cost 16000ms :(
Posted by bluejoe <bl...@gmail.com>.
Thank you, It seems that there is something wrong in my eclipse. The simplest TestCase runs very very slowly in it. When I replace the eclipse with a new version, the cost turns to be 300ms and even more quickly than that, it's so nice, thank you!

Re: The loading of such a template cost 16000ms :(
Posted by Nathan Bubna <nb...@gmail.com>.
16 seconds? I'm with Byron on this. Something is wrong, and it's
not with your template or Velocity's parsing. This template is
neither long enough nor complicated enough to get anywhere close to
that time for parsing on any sort of modern system. What system is
this on? Are you using a custom resource loader? URLResourceLoader
over a slow connection? What profiler are you getting the 16000ms
time from? It would be best to know exactly where in your system this
time is being spent.

This template is created automatically by another Velocity client class (I named it as TemplatePublisher), so it is too ugly and long. Who can tell me how to optimize this template to make the loading time shorter?
