This 487 improvement only works on datasets with enabled compression, 488 disabled deduplication and sha256 checksums. ZFS will now 489 compare the checksums of incoming writes to the checksum of 490 the existing on-disk data and avoid issuing any write I/O 491 for data that has not changed. This will reduce I/O as well 492 as space usage because if the old block is referenced by 493 a snapshot, both copies of the block are kept even though 494 both contain the same data.</para> 495 </sect4> 496 </sect3> 497 </sect2> 498 499 <sect2 xml:id="userland"> 500 <title>Userland Changes</title> 501 502 <para revision="255321">On platforms where &man.clang.1; is the default 503 system compiler (such as i386, amd64, arm), GCC and GNU libstdc++ are no 504 longer built by default. &man.clang.1; and libc++ from LLVM are used on 505 these platforms by instead.
