It is not spam to ask for review. He was uncertain, and asked for some clarification. -- Eitan Adler From owner-freebsd-hackers@FreeBSD.ORG Sun Oct 7 17:06:27 2012 Return-Path: Delivered-To: freebsd-hackers@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [69.147.83.52]) by hub.freebsd.org (Postfix) with ESMTP id E5C9B1065670 for ; Sun, 7 Oct 2012 17:06:27 +0000 (UTC) (envelope-from wojtek@wojtek.tensor.gdynia.pl) Received: from wojtek.tensor.gdynia.pl (wojtek.tensor.gdynia.pl [89.206.35.99]) by mx1.freebsd.org (Postfix) with ESMTP id 19AEB8FC08 for ; Sun, 7 Oct 2012 17:06:26 +0000 (UTC) Received: from wojtek.tensor.gdynia.pl (localhost [127.0.0.1]) by wojtek.tensor.gdynia.pl (8.14.5/8.14.5) with ESMTP id q97H0RMq016006; Sun, 7 Oct 2012 19:00:27 +0200 (CEST) (envelope-from wojtek@wojtek.tensor.gdynia.pl) Received: from localhost (wojtek@localhost) by wojtek.tensor.gdynia.pl (8.14.5/8.14.5/Submit) with ESMTP id q97H0QL4016003; Sun, 7 Oct 2012 19:00:27 +0200 (CEST) (envelope-from wojtek@wojtek.tensor.gdynia.pl) Date: Sun, 7 Oct 2012 19:00:26 +0200 (CEST) From: Wojciech Puchar To: Brandon Falk In-Reply-To: <5069C9FC.6020400@brandonfa.lk> Message-ID: References: <5069C9FC.6020400@brandonfa.lk> User-Agent: Alpine 2.00 (BSF 1167 2008-08-23) MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII; format=flowed X-Greylist: Sender passed SPF test, not delayed by milter-greylist-4.2.7 (wojtek.tensor.gdynia.pl [127.0.0.1]); Sun, 07 Oct 2012 19:00:27 +0200 (CEST) Cc: freebsd-hackers@freebsd.org Subject: Re: SMP Version of tar X-BeenThere: freebsd-hackers@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Technical Discussions relating to FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 07 Oct 2012 17:06:28 -0000 > I would be willing to work on a SMP version of tar (initially just gzip or > something). > > I don't have the best experience in compression, and how to multi-thread it, > but I think I would be able to learn and help out. gzip cannot - it is single stream. bzip2 - no idea grzip (from ports, i use it) - can be multithreaded as it packs using fixed large chunks.

For proof, look at Mark Adler's pigz program, which does exactly this. GZip decompression is admittedly trickier. > bzip2 - no idea bzip2 is block oriented and can be multi-threaded for both compression = and decompression. Tim
