Subject [jira] [Commented] (COMPRESS-233) Microbenchmarking TarBuffer#isEOFRecord
Date Wed, 17 Jul 2013 14:48:52 GMT


Stefan Bodewig commented on COMPRESS-233:

To me it is more about readability than about performance.

Worst case we are wasting the size of on record (512 bytes by default) and not gaining performance.

> It's possible to speed up the regular checking of isEOFRecord by creating a buffer that
is all zeros then using the Java primitive Arrays.equals function.  My bench-marking puts
it at roughly 1/3 the time per check.  No unit tests were harmed in the production of these
