We are trying to troubleshoot slow performance. A lot of my NT client log files show messages like this about oplock break issues. [2003/10/09 12:50:39, 0] smbd/oplock.c:(1008) request_oplock_break: no response received to oplock break request to pid 2907 on port 61752 for dev = 40240002, inode = 29, file_id = 2 64 [2003/10/09 12:51:03,...

Now that I have a working kvm setup, I thought I'd finally try how Zimbra works. This is mainly some microbenchmarking, so it may not have much to do with actual performance in real life. Setup: - 1GB memory given to kvm (from host's 2GB) - Intel Core 2 6600 (kvm uses only one CPU) - CentOS 5 - 15GB qcow2 image on XFS filesystem - Zimbra 5.0 RC2 RHEL5 x86_64 - Dovecot latest hg, dbox format Both Zimbra and Dovecot were tested running on the same kvm image...

Hey, I have installed Ubuntu 8.10 with FV mode. I use this server for web server (command line mode only, no X window) So should I hack my current installation into a PV mode for production use? In fact, any min. performanc gain suppose I should get? (Any bechmark?) Thanks. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hello I am having a hard time with users using POP while leaving mailboxes of several gigabyte cumulated. This causes a lot of disk I/O and kills performancs for everyone. I try to encourage people migrating to IMAP, but that migration will take some time, and therefore I am looking for alterantive ways to workaround the problem. I found pop3-throttle-plugin.c, which seems a smart way to solve the problem, unfortunately it comes with no documentatio...

As a follow up from my previous post, I am pondering some changes to my env. I read that with AR I should change the verification timeout to be lower than the MySQL db Interactive_timeout. Now, I have done some performancing tuning to mysql in LAMP env''s but not RoR. MySQL typical set the default interactive_timeout to 8hrs (28800) this has bitten me a few times with sleeping processess or stale connections. What I have done in the past was optimize mysql with the following variable changes (/etc/my.cnf) w...

...e to know from someone here, wether this device will support faxing on my local asterisk server, I have had success sending and recieving faces with an x100p, and recall that in the old documentation, they mention that if I send/recieve faxes, that it all should be done on the local server for best performanc, so Im asuming tha this device may apply because there will be an ethernet cable between the FXO and the asterisk server? thanks! ____________________________________________________________________________________ Catch up on fall's hot new shows on Yahoo!

...on my 700Mhz Thinkpad T-20 (256 MB RAM) with Windows NT: var(matrix(rnorm(4000000),ncol=4,nrow=1000000)) This also has the virtue of being quite readable. You could allow an arbitrary covariance matrix and mean vector and it increases the time slightly, but still only about 5 seconds. Regarding performance, having tons of RAM is crucial. My Windows NT and the few Office applications that are always running claim at least 100MB RAM according to the performanc monitor; that doesn't leave much for the large objects you tend to create when you vectorize unless you have at least 256MB.

...as the subject of earlier spirited > discussion in this thread. Don't be fooled here by words "ordered" and "completed" - it is HW design items and actually written poorly. Just assume that SYNC_MB is absolutely the same as SYNC for any CPU and coherent device (besides performance). The difference can be in non-coherent devices because SYNC actually tries to make a barrier for them too. In some SoCs it is just the same because there is no need to barrier a non-coherent device (device register access usually strictly ordered... if there is no bridge in between). > &g...

Hi, Redhat announced RHEL 5.1 on Nov 07, so hopefully CentOS 5.1 will be ready shortly. But I get kind of nervous of the arrival of 5.1. My problem is: I have hundreds Centos 5.0 boxes just finished installation and I will continue to install and upgrade hundreds more in next few months. With the arrival of Centos 5.1, I don't like to reinstall them anymore but continuous upgrade instead

Hi, I still have a problem with samba and profiles. The profile is correctly written to the profile share. but when i logon a other computer, logon takes ages.. and im unable to do anything registry is locked for example. ( see logs below ) when i copy the network profile to the local computer there is no problem. ( because the local profile is used ) OS : Linux Kernel 2.6.11 ( custom build
