Hi,
I've noticed that Gradle is much slower compared to ant. A build
that copies
only one file takes ~6 seconds.
Gradle is slower than Ant, but six seconds is a lot.
On my machine (Mac OS X and 1.5 year old Core Duo 2.33 GHz) such a
simple build would take one second to execute.
If you go to GRADLE_HOME/samples/tutorial and execute:
gradle -bantChecksumfile checksum
How long does this take on your machine?
Are there any thoughts of focusing on the aspect of performance?
What about
gradle compiling the gradlefile into a .class file and using it in
subsequent builds (if not changed of course)?
In general we want Gradle to be as fast as possible. Some aspects are
it in our hand. For example the groovy startup time is something like
0.3 seconds on my machine, compared to 0.1 seconds of Java. It looks
like there are possibilities to improve this but I don't know what
priority this has within the Groovy team. The other aspect not in our
hands is the runtime performance of Groovy. This is a main focus of
the Groovy guys right now and with 1.6 this will already improve
significantly with still a lot of potential for improvement in the
future. The third aspect is compile time speed. This will also be
improved with 1.6. But of course we could use caching and timestamps
to avoid this step altogether. Yet for a simple build script, I would
think the compile time of the gradlefile is insignificant. The fourth
aspect is the Gradle processing. Again I don't think this is
significant. Anyway, we need to do some proper profiling of gradle
builds to get a solid understanding here.
But six seconds for a simple build I consider as not acceptable. I'm
curios why it takes so long on your machine.
