similar to: enabling async feature

Hello, Is there any straightforward way to see whether Samba is using "asynchronous i/o"? In other words, if you specify in smb.conf to use aio for all transfers larger than 1 KB (pretty much everything), how can you tell that aio is actually being used? Are there any counters in Linux or in some samba logs that you can see incrementing over time? Thanks in advance. -- Andy

The long term plan is to get all of Dovecot disk I/O asynchronous. The first step to that direction would be to make dbox/mdbox I/O asynchronous. This might also allow mbox/maildir to become partially asynchronous. http://www.dovecot.org/list/dovecot/2009-December/045481.html already started describing how the lib-storage API could be changed to support high-latency storages. Adding support for

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. To enable this new feature, Samba must be compiled to include the --with-aio-support configure option. In addition, the "aio read size" and

Hi I recently started to look into Samba source code and SMB protocol . I saw that SMBv3 has an compression feature but I couldnt find any source code related to it. I tried sending compression_capabilities in negotiate request packet but there was no correspoding response. Isn't feature implemented yet? If not when are you planning to implement it? Thanks

Hi, I have problem with my samba. I have shared folder which contains many smaller files (few MB each), this files are stored on very fast disk array. Locally, from that machine I can read this files in parallel with speed about 500-1000 MB/s, but when I read them through samba, I get only 50-100 MB/s on a 10 gigabit network. I tried to find the problem, so I analyzed strace logs and found out,

Hello list, I am looking to enable samba aio on my Wheezy test box (I have version 4.1.17 from back ports). The output of smbd -b shows that the stable packages for my distro are not compiled using --with-aio-support. It appears that without recompiling I can use vfs objects = aio_pthread to achieve a similar effect? I'm aware that this somewhat dips into Debian specifics, but I figured

I'm trying to learn more about samba by experimenting with samba on FreeNAS. This involves a certain amount of reading how default smb4.conf parameters are set in FreeNAS and then reading the manpages for those parameters. Async I/O is implemented in samba in freenas via the aio_pthread VFS module. The manpage for vfs_aio_pthread states: "the smb.conf parameters aio read size and aio

[RFC] Virtual Machine Device Queues (VMDq) support on KVM Network adapter with VMDq technology presents multiple pairs of tx/rx queues, and renders network L2 sorting mechanism based on MAC addresses and VLAN tags for each tx/rx queue pair. Here we present a generic framework, in which network traffic to/from a tx/rx queue pair can be directed from/to a KVM guest without any software copy.

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 ?
