Re: [zfs-discuss] OpenSolaris vs Linux
Russell, thanks much for the testing data! Although out of date and not a server data, not what I am looking for, the data is valuable on the thread for others that may have the need. And one day, we can have open storage validated open performance data as a brand anyway, since we are talking about OpenSolaris vs Windows now, I do have another request to the list, on NAS protocol and performance. Any comments on OpenSolaris native CIFS vs. Windows SMB 2.0? Data or theory, all welcome, thanks! See below for tech history, if not already clear. I doubt many folks still remember IBM invented SMB (CIFS) and Sun invented NFS, and NetApp did not invent NAS! zStorageAnalyst Barry Feigenbaum originally designed Server Message Block (SMB) at IBM to enable local file-access into a networked file-system. Microsoft merged the SMB protocol with the LAN Manager product and continued to add features to the protocol in every version of Windows. At around the time when Sun Microsystems announced WebNFS (an extension to the NFS file system), Microsoft launched an initiative in 1996 to rename SMB to Common Internet File System (CIFS), and added more advanced features. Microsoft submitted some partial specifications as Internet-Drafts to the IETF though these submissions have expired. Because of the importance of the SMB protocol in Microsoft Windows platform, from the open source camp, the Samba project originated with the aim of reverse engineering and providing a free implementation of a compatible SMB client and server for use with non-Microsoft operating systems. With Windows Vista, Microsoft introduced SMB 2.0. And with Windows Server 2008, SMB 2.0 again the official name for MS file service protocol, not CIFS again. And MS claims Windows SMB 2.0 bring huge performance gain. - Original Message - From: Joerg Schilling joerg.schill...@fokus.fraunhofer.de To: russell.aspinw...@flomerics.co.uk; bfrie...@simple.dallas.tx.us Cc: zfs-discuss@opensolaris.org Sent: Tuesday, December 09, 2008 2:16 PM Subject: Re: [zfs-discuss] OpenSolaris vs Linux Bob Friesenhahn bfrie...@simple.dallas.tx.us wrote: Your data is surely out of date.

Windows itself inserts anti-virus type checking into your application as it runs. Windows executes your application slower with each new service pack update and more and more run-time safety checks are added. If you build your application with recent Visual Studio versions, then it may run vastly slower by default. Adobe developers found that debug versions of Photoshop became completely unusable due to all the added background checking. Much of the checking can be turned off, but it may require rebuilding the SDKs with a special define. There may be specialized areas where Windows does shine, but it is clearly not in application execution times. It is possible that someone will develop a Solaris-specific virus, but that seems unlikely. Windows is paying a high price for its policies.

Microsoft Windows is surely faster than any Unix because it executes the foreground task (the program with the highlighted title bar) with far more priority than any other task. Microsoft Windows XP Home Edition is fastest since it maximally cranks up the priority on the foreground task given that home users can only realistically work on one thing at a time with their 17 displays. Generally people find that server oriented OSs feel slower because they are optimized to do more than one thing at once. They are optimized for throughput rather than instantaneous response time. Server OSs focus on providing data caching which is likely to speed up the next similar request. Regardless of many people's wrong impressions, Solaris and OpenSolaris are a server/enterprise type OS intended to sustain heavy multi-user application loads, and not a desktop productivity OS. OpenSolaris just puts more modern Linux-like decorations on top than Solaris 10. The tiger has not lost its stripes. Linux does reasonably well for desktop productivity and does quite well at implementing the popular LAMP server configuration. The LAMP server configuration is not particularly demanding and any server limitations may be solved by simply replicating the server a few more times. I have no doubt that Linux will match Solaris performance in small LAMP style servers, and also have no doubt that Solaris will excell when faced with huge application work loads while Linux suffers.
