Hi,
I use JRebel and have a performance issue some of the time. Some request
take 2sec instead of 100ms for no apparent reasons.
After some research I found out that this was only happening when JRebel
was enabled and that it did not happen with version 2.3.16.3.
So I searched for the cause and found that a little bit of code was
removed between the 2 versions and leading to a major performance
difference.
Removed code
PackageBasedActionConfigBuilder.buildUrlSet l.461 (v 2.3.16.3) :
if (includeJars == null) {
urlSet = urlSet.exclude(".*?\\.jar(!/|/)?");
} else {
...
}
The removed code made the size of urlSet go from 140 to 3. This urlSet
will latter be used to explore and find Framework relevant resources
hence the performance hit.
*Note:* I probably would not have detected the issue if I was not using
JRebel but this should in all logic impact every Struts user since this
code impacts server startup. I speculate that in my case it adds about 2
seconds to server startup which is a pity.
Questions:
Why was this removed? Could you make this behavior configuration
sensitive rather than altogether gone? How can I work around it if at
all possible?
Best regards,
Thim.
