Hi all, If I have a linux server running samba for filesharing and I use NFS to make these shares available on another linux server that also runs samba to share the same shares will the locking still work properly? I can use this to get around an issue with multiple authentication domains and I suspect NFS is less chatty than SMB anyway so will mean a peformance win as well across the WAN. Can

We have some HDS storage that isn''t supported by mpxio, so we have to use veritas dmp to get multipathing. Whats the recommended way to use DMP storage with ZFS. I want to use DMP but get at the multipathed virtual luns at as low a level as possible to avoid using vxvm as much as possible. I figure theres no point in having overhead from 2 volume manages if we can avoid it. Has anyone

Hello, I'm trying to configure shared mailboxes with ACL. My problem is FS layout. Our maildirs is completely outside of home dirs (home dirs is on pure SSD zpool, maildirs on separate HDD zpool). We are using checkpassword auth, which sets mailbox_location for each user. Layout is following: maildirs: /dpool/mail/maldirs/user-uuid/ home is: /dpool/mail/home/user-uuid/ index &

Hi, has anyone run httperf in Xen.if so cna you share the peformance. Also can someone please send me the source for this. the HP site that hosts it does not respond and i do see any other sites that have the source for httperf. Thanks PKrishna _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Samba Team, How do I create simulated load on a samba server? I wish to use feedback-directed program restructuring on AIX 5.2 to determine if performance can be improved by rearranging the executable generated by the IBM 6.0 compiler. Mostly I'm determining what the upper bound on smbd's is in a multiprogramming environment. I'm currently running about between 800 and 1000

Does anyone know the difference in performance between an ActiveRecord::find and Enumerable::find (or detect since ActiveRecord redefines the find method) for a has_many association? Here is an example: I have a list that has 10 lines and I want to find the first blank line. Which approach would be better? list.lines.detect { |line| line.content == nil } or

Hi all, Since I've got no reply on redhat cluster list, I'm trying here ... I'm testing a rhcs4 cluster with gfs. I noticed some poor performance while tarring data from a gfs volume to a local disk from both nodes at the same time, so I deceided to have a closer look. Here are the bonnie++ results: http://jure.pecar.org/gfs/ I don't know what to think of these ... but I doubt

Hello, After setting up Samba 3.5.6 on CentOS 5.5 (built from sources) I have noticed a strange problem. Windows 2003 servers participating in this Samba domain do not receive domain groups list when I, say, try to assign security credentials for a file/folder. When I choose domain as source, search reveals only technical group names and individual domain users names. No domain group names

Hello again, Thanks James for your replies. In regards to the slow read/write, the software vendor is aware of the problem, at some stage they will buffer the read/write, but it won't happen overnight, the binary file is quite complicated. So there are no updates available for this particular issue and I don't expect any for a couple of months. The software in question can generate

Why ? I disagree, the flag should be honored when set in any architecture. PowerPC is no

Hi, I'm running centos-4.4 on an SMP system with 4 dual core opterons (2.4 GHz), and 16 GB memory. The disk drives are 500 GB SATA-Drives. Wondering about times for dd command performance and rm command performance in an empty machine (the filesystem has been made with "mkfs.ext3 /dev/sd...", nothing more) 1. Making a new 3 GB (1024 x 3megabytes blocks) file with dd needs 10.18

As far as I can see, transcoding could be usefull for people who do not primarly care about quality but about filesizes. One could assume that such a user would have a collection of mp3's at 128kbps or higher bitrates, and uses an encoder like BladeEnc or Xing. He wants to take uses of ogg's supposed quality and transcode his 128-or-higher files into 96 or 112kbps oggs to save diskspace.

So here''s a random question: if a (Ruby) multi-threaded rails server could exist (bug free), would it be faster than using a mongrel cluster? (I.e. 10 mongrel processes versus 10 Ruby threads). I''m not sure if it would. RAM it might save, though. Any thoughts? -Roger -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi people. So I got Steam running properly in WINE by reverting to version 177 of the nVidia driver. Now I have a new problem. I have really shitty performance for Source games in WINE. This means rainbow-y colors, glistening walls, at ~13 fps with all lowest graphics settings. High quality native linux games run beautifully at all highest settings, including Penumbra and Prey and Quake 4. I
