One easy way to improve performance a lot

[Daniel.Sun]

Hi all,

I found more than 90% time is spent in compiling.
So I think caching these latest compiled groovy class will improve
performance a lot.
The cache pool should be provided with gdk and instance of the pool should
be store in a Thread which is started when we run our application.

pseudocode as follows:
find the requested class from cache.
if (the class is cached) {
if (modifying timestamp of groovy script file > modifying timestamp of
class's groovy script file which is also in the cache) {
recompile the groovy script file and cache it
} else {
return the requested class
}
} else {
compile the groovy script file and cache it
return the requested class
}

Best regards,
Daniel.Sun

that's how it is working, or not?

Yeah, now I'm using JSR223 Groovy-Engine which can cache scripts, so I don't
care whether Groovy will cache scripts or not :)
Thanks for your response :)
