Java’s ZipFile performance
I have an application that scales well up to around five threads a core, due to the mix of IO and CPU that it does.
That is, you give it more threads, and the throughput increases; the overall time goes down.
The following graph shows, in blue, the Sun’s java.util.zip.ZipFile time to complete a set of unzips on an increasing number of threads:
Wait, what the cocking shit.
