similar to: SMB2 write performace slower than SMB1 in 10Gb network

Quick question. In my host, I've got two processors with each 6 cores and each core has two threads. I use iometer to do some testings on hard drive performance. I get the idea that using more cores give me better results in iometer. (if it will improve the speed of my guest is an other question...) For a Windows 2012 R2 server guest, can I just give the guest 24 cores? Just to make

Hi all, I currently have a OCZ Vertex 4 SSD as a ZIL device and am well aware of their exaggerated claims of sustained performance. I was thinking about getting a DRAM based ZIL accelerator such as Christopher George''s DDRDive, one of the STEC products, etc. Of course the key question i''m trying to answer is: is the price premium worth it? --- What is the (average/min/max)

Hi there. I just got a new Adaptec RAID 51645 controller in because the old (other type) was malfunctioning. It is paired with 16 Seagate 15k5 disks, of which two are used with hardware RAID 1 for OpenSolaris snv_98, and the rest is configured as striped mirrors as a zpool. I created a zfs filesystem on this pool with a blocksize of 8K. This server has 64GB of memory and will be running

I'm seeing some really poor performance out of my FreeNAS (ver 9.10) machine, running Samba "4.3.6-GIT-UNKNOWN". I'm using IOMeter to benchmark sequential reads, and getting around 35-40 MB/sec, which seems unusual. Mostly, I'm hoping someone can point me in the direction of a decent tuning guide for a SOHO machine running Samba, but if you're inclined, I'll delve

On a 32bit Windows 2008 Server guest VM on a CentOS 5 host, iometer reported a disk write speed of 37MB/s The same VM on a CentOS 6 host reported 0.3MB/s. i.e. The VM was unusable. Write performance in a CentOS 6 VM was also much worse, but it was usable. (See http://lists.centos.org/pipermail/centos-virt/2012-August/002961.html) With iometer still running in the guest, I installed tuned on

Cc the QEMU Block Layer mailing list (qemu-block@nongnu.org), who might have more insights here; and wrap long lines.

Hello list, I setup Iometer to test AIO for 100% random read. If "Transfer Request Size" is more than or equal to 256 kilobytes,in the beginning the transmission is good. But 3~5 seconds later,the throughput will drop to zero. Server OS: Ubuntu Server 14.04.1 LTS Samba: Version 4.1.6-Ubuntu Dialect: SMB 2.0 AIO settings : aio read size = 1 aio write size = 1 vfs objects =

I have created shell script for MRTG statistics of droped/rejected packets: ftp://slovakia.shorewall.net/mirror/shorewall/mrtg/ http://slovakia.shorewall.net/pub/shorewall/mrtg/ rsync://slovakia.shorewall.net/shorewall/mrtg/ example: http://slovakia.shorewall.net/pub/shorewall/mrtg/example/ It is not based on /var/log/messages (syslog), but iptables counter. A lot of packets are droped/rejected

When testing out 16KB blocks with direct I/O [1] on 3.3-rc6, we quickly see btrfs_search_slot returning positive numbers, popping an assertion [2]. Are >4KB block sizes known broken for now?

Hello: Sorry for asking iozone ques in this mailing list but couldn't find any mailing list on iozone... In IOZone, is there a way to configure # of outstanding requests client sends to server side? Something on the lines of IOMeter option "Number of outstanding requests". Thanks a lot!

When sending print jobs back to back .. say 5 times or so .. sometimes a character or two get droped .. causing the printout to be some what garbled. This happens from NT as well ... heh .. which is really fun when they're printing postscript .. cause when the 1st character or so is droped from a postscript print job .. it's postscript commands are printed out as ascii. Is anyone else out

Hello Jeremy, > OH - that's *really* interesting ! I wonder how it is > changing the SMB3+ redirector to do this ? It looks like applications could do something and give a hint to SMB3+ redirector, so far not quite sure how to make it, per process monitor (procmon) could show that write I/O size seems could be pass from the application layers,

Hi everyone, I'm having the following situation: I need to migrate all SMB file services to a new appliance that only supports the SMB2+ protocol. Unfortunately, there are still some very old Linux clients ("modinfo cifs" says version 1.60) that do only speak SMB1 and need to access these shares after the migration. Is it possible to have a Linux with a modern Samba

Hello everyone: I keeps using rsync to backup my files on my laptop from one folder to another, and to reduce disk usage, so I use "--link-dest" option for incremental backup like this: *rsync -a --link-dest=/local/old /tmp/myfile /local/new* And "/local/old" is backuped some days ago, I use "--link-dest" option to keep unchanged files as links to new destination

Hello, I'm running Asterisk on a CentOS 64-bit server. . Asterisk if I compile using the ./configure --libdir=/usr/lib64 instead of ./configure have a relative gain performace.? Has anyone done any comparison? Is there any way in the compilation or even in settings that I can improve the performace of the asterisk? tks Eduardo -------------- next part -------------- An HTML attachment was

I''ve just uploaded a new binary release of the GPL PV drivers for Windows - release 0.6.3. Fixes in this version are: . Should now work on any combination of front and backend bit widths (32, 32p, 64). Previous crashes that I thought were due to Intel arch were actually due to this problem. . The vbd driver will now not enumerate ''boot'' disks (eg those normally serviced
