Hi Roch, 1) The memory copy operations are expensive... I think the following is a good intro to this problem: "Copying data in memory can be a serious bottleneck in DBMS software today. This fact is often a surprise to database students, who assume that main-memory operations are "free" compared to disk I/O. But in practice, a welltuned database installation is typically not I/O-bound." (section 3.2) http://mitpress.mit.edu/books/chapters/0262693143chapm2.pdf (Ch 2: Anatomy of a Database System, Readings in Database Systems, 4th Ed) 2) If you look at the TPC-C disclosure reports, you will see vendors using thousands of disks for the top 10 systems. With that many disks working in parallel, the I/O latencies are not as big as of a problem as systems with fewer disks. 3) Also interesting is Concurrent I/O, which was introduced in AIX 5.2: "Improving Database Performance With AIX Concurrent I/O" http://www-03.ibm.com/systems/p/os/aix/whitepapers/db_perf_aix.html "Improve database performance on file system containers in IBM DB2 UDB V8.2 using Concurrent I/O on AIX" http://www-128.ibm.com/developerworks/db2/library/techarticle/dm-0408lee/ Rayson > > -r > > > > > Thanks, > > - Ryan > > -- > > UNIX Administrator > > http://prefetch.net > > ___ > > zfs-discuss mailing list > > zfs-discuss@opensolaris.org > > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss > > ___ > zfs-discuss mailing list > zfs-discuss@opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss > ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Direct I/O ability with zfs?
1) Modern DBMSs cache database pages in their own buffer pool because it is less expensive than to access data from the OS. (IIRC, MySQL's MyISAM is the only one that relies on the FS cache, but a lot of MySQL sites use INNODB which has its own buffer pool) 2) Also, direct I/O is faster because it avoid double buffering.

Even a good compressor, if operated on a good random generator's output, will only end up burning cycles, but not reducing the data size. Hence, is the request here for the compressor module to 'adapt', kind of first-pass check the input data whether it's sufficiently low-entropy to warrant a compression attempt ? If not, then what ?

See ZFS being ported to FreeBSD. Agreed. Why does everyone need to be compatible with Linux?? Why not Linux changes its license and be compatible with *BSD and Solaris?? Rayson I really see no point wasting Open Solaris resources to keep ZFS dual licensed. And frankly, it would be mostly Sun's resources. I would rather like to spend those resources on something more important. -- Best regards, Robertmailto:[EMAIL PROTECTED] http://milek.blogspot.com ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] Re: Cluster File System Use Cases
I read this paper on Sunday. Seems interesting: The Architecture of PolyServe Matrix Server: Implementing a Symmetric Cluster File System http://www.polyserve.com/requestinfo_formq1.php?pdf=2 What interested me the most is that the metadata and lock are spread across all the nodes. I read the "Parallel NFS (pNFS)" presentation, and seems like pNFS still has the metadata on one server... (Lisa, correct me if I am wrong). http://opensolaris.org/os/community/os_user_groups/frosug/pNFS/FROSUG-pNFS.pdf Rayson ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Rayson By not installing the two data services (II and SNDR), one is left with a filter driver framework, but of course with no filter drivers.

Re: [zfs-discuss] How to download the source code?
1) Take a look at the "ZFS Source Tour": http://www.opensolaris.org/os/community/zfs/source/ 2) You may also want to talk to the FreeBSD zfs port maintainer: http://perforce.freebsd.org/depotTreeBrowser.cgi?FSPC=//depot/user/pjd/zfs 3) The source of ZFS is in a few different directories: Main FS directory: http://cvs.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/common/fs/zfs/ zpool command: http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/cmd/zpool/ zfs command: http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/cmd/zfs/ libzfs: http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/lib/libzfs/ Rayson On 2/23/07, Ludovic Gele <[EMAIL PROTECTED]> wrote: Hi folks, I want to try to port ZFS under OpenBSD, but I'm not able to find the archive of the source code of this filesystem.
