Dear, Does dovecot support aio(asynchronous IO)? Or do we have a plan/need to support it? Thanks!

hello, on my stream I've been using liveice, but it has a rather nasty habit of stopping at its own leisure! i'm wondering if anyone is using iceS beta with any stablilty? m --- >8 ---- List archives: http://www.xiph.org/archives/ icecast project homepage: http://www.icecast.org/ To unsubscribe from this list, send a message to 'icecast-request@xiph.org' containing only

I'm looking into trying out AIO on one of our file servers in the office but I can't find any info on what the values for "aio read size" and "aio write size" correspond to. Is it a buffer size of some sort or a tuning type parameter were it allows the socket to read/write x blocks? Thanks, David Miller

hi, i'm trying to get the asynchronous file transfer to work on a FC4 for the latest samba verion (3.0.20b). The things i've done: ./configure --with-aio-support ... included "aio read size = 1" and "aio write size = 1" in the smb.conf file What did i forget?? michiel ========================= uname -a Linux wired11 2.6.12-1.1398_FC4 #1 Fri Jul 15 00:52:32 EDT

One more data point for comparison I installed the stock samba 4.2 rpm on a centos 7 machine and ran the same diskspd tests against a share configured with: vfs objects = aio_pthread aio read size = 1024 aio read size = 1024 smb2 leases = yes I get 27MB/s with 4k blocks and 145MB/s with 64k blocks. Disabling cacheing by passing the -h switch to diskspd lowered these to 72MB/s

I'm trying to install samba-3.0.20 on aix 5.2, and I don't want to use aio, but the build process is compiling it in anyway. By default, it isn't supposed to build in aio support, but it does. When I pass --with-aio-support=no to configure, it also builds in support. It builds in aio support whether I use gcc or xlc. Here's what ldd shows: # ldd bin/smbd bin/smbd needs:

Hi list, I have been trying to enable AIO on ARMv5 Samba built with kernel headers 2.6.31.8, the configure indicated that AIO is supported via kernel headers and all went smooth (regarding the build process). Once I added the smb.conf 'aio write size=1' and tried to perform a file copy to the Samba share I noticed that 32K of the file (of the 1GB file) have been copied to the share but

Maybe it''s something I''m doing wrong, but I have a 15gb image that I use with disk = [ "tap:aio:/root/images/vista32.img,hda,w" ] It was working fine on Friday, but today it failed to boot with an error message. The same works fine when I replace "tap:aio:" with "file:". It seems like qemu-dm tries to open the file with the "aio:" still

Looked through the smb.conf.5 from 3.0.20pre2 for additional info on the aio settings but didn't seem to find them. I'm setting this up on AIX 5.2 and just wondered what where recommended starting values...and non-zero values activate the AIO code paths? Cheers, Bill

when installing samba from FreeBSD ports collection, I can choose AIO support, which leads to ... checking whether to support asynchronous io... yes checking for aio_read in -lrt... no checking for asynchronous io support... no checking for 64-bit asynchronous io support... no does it mean aio was not enabled ? Cheers, Ilia Chipitsine

Hi there I am analyzing disk performance. I'm testing raw (tap: aio) and lvm (phy :). The tests I'm doing on a SLES11SP3, cpu I7, 4GBRam, disco-SATAII 7200rpm. With phy: lvm achievement 70-80MiB / s (an acceptable value) With tap: aio: file.raw achievement 5-9MiB / s, which is very low ... 10MiB / s is what you should expect access to a tap: aio: file.raw? or I have something

Hi, I have a FreeBSD 7.2 machine with Samba 3.4.5 with aio support enabled. If I try to upgrade to Samba 3.5.2 from source aio support compiles but I receive "Abnormal server exit: Failed to setup RT_SIGNAL_AIO handler" fatal error from smbd. Without aio 3.5.2 too works nice. Any hint please what has been changed from 3.4.5 to 3.5.2 regarding aio? Or what special compile option would

I'm tuning a samba 4.3 install on freebsd and I'm confused about aio settings. I've loaded the freebsd aio kernel module and tried various values or aio read size and aio write size, but it seems to make no difference in the speed. Using MS diskspd against a samba share from a fast zfs pool I get something like 25MB/s tops. That's well below the capacity of my Gb network and

hi, i just have some questions about specific (uncommon) compile options and aio-settings in smb.conf: Asynchronous IO Support ======================= "Experimental support for async IO has been added to smbd for certain platforms.

Hello, We are using libvirt 0.8.3 to build KVM guests (KVM version is qemu-kvm 0.12.5). I see kvm supports aio flag with either native or threads option.
