Yeah, a lot of people were getting that, as a result of some drm/ttm hugepage usage. Christian, did a fix ever end up going out?

Hi, I'm using py-rrdtool 0.2.1 with rrdtool 1.3.0 under 7.0-STABLE, and there's a couple of things about this new version of rrdtool that hurt performance under FreeBSD, but apparently help on whatever they tested on. For every update, the database file is opened, mapped into memory, madvise() is called, contents are modified, msync() is called, and the file is unmapped and closed:

Dear all, When I debugged the execution performance of an application using strace, I found there are some system calls like open and stat64 which run faster on XenLinux than the standard Linux. The following is the output of running "strace -c /bin/sh -c /bin/echo foo" on both systems. An open call runs averagely 109 usec on standard Linux but only 41 usecs on XenLinux. An stat64

Hi! I'm currently hunting a strange problem and looking for help! I have a samba3 fileserver (currently samba-3.0.20b, but problem can be reproduced with samba-3.0.7, but _not_ with samba2 like 2.2.8a), and I see performance problems when writing files with MS word 2002 SP3 from a NT4.0 (SP6a) workstation. Saving even the smallest file takes more than 10 seconds! Copying files with Windows

Listing directories with many files (10000+) from a Windows client is nociceably slower when vfs_fruit is enabled on the samba server compared to the same setup without vfs_fruit. On my setup it's roughly 2.5 times slower. To me it looks like this is caused by the getxattr call which is only present with vfs_fruit activated and introduces an additional delay of ~ 0.00033 s per listed

Hi, my environment: Win2003 AD + Samba4 as second RW DC on debian wheeze. Samba compiled from source: samba --version Version 4.1.0pre1-GIT-c932b13 Installed Samba4 according these: https://wiki.samba.org/index.php/Main_Page https://wiki.samba.org/index.php/Samba4/HOWTO/Join_a_domain_as_a_DC https://wiki.samba.org/index.php/Samba4/Winbind Everything went good according tutorial, until I try get

Thank you!

Thanks for the interesting puzzle to crunch! Looking at these few bread-crumbs, I wager an educated guess that this loops in `sendcmd()` (where CLI child processes talk to a daemonized copy which tracks the timers for events), around here: https://github.com/networkupstools/nut/blob/v2.8.0/clients/upssched.c#L583-L626 for the daemon and here for the child:

Hi Jones, many thanks again four your help and your time. Thanks for the patch too - I'll check it up. On my Ubuntu, there is a Samba 4.1.6. I'll install the samba source package, and will try to apply the patch, then - I hope - the package will be compiled as well. I'll notify to you about the result. (First, I need to upgrade that server.) Thanks again, Ervin On Thu, Apr

Hi, I ran the strace command while upssched was 100% CPU hungry.

Hai, Can you tell the following that helps. OS ? Samba Version? ( pre-builded or source ) Kernel version? I think you need to wait for 4.9.4 if all patches ive seen on vfs_fruit are getting in. These might help. Go through bugzilla, you might find more about this here. Greetz, Louis > -----Oorspronkelijk bericht----- > Van: samba [mailto:samba-bounces at lists.samba.org]

Hi : I looked at the help for system.time but I still have the following question. Can someone explain the output following output of system.time : user system elapsed 12399.681 5632.352 56935.647 Here's my take based on the fact that I was doing ps -aux | grep R off and on and the total amount of CPU minutes that got allotted before the job ended was about 5 hours and the

This small series introduces TTM helper functions as well as Nouveau hooks that are needed to ensure buffer coherency on ARM.
