I removed the O_CREAT|O_EXCL checks and added check to exclude O_DIRECTORY, but it is not working, opening of files fails and I don't know why. I can see in strace logs that openat syscall in vfs_aio_pthread was successful, but it still fails and this messages are logged: [2016/04/28 13:28:59.691782, 5, pid=5623, effective(32697, 10513), real(32697, 0)] ../source3/smbd/open.c:2551(open_file_ntcreate) open_file_ntcreate: FILE_OPEN requested for file subor and file doesn't exist.

...rn 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 write size must also be set appropriately for this module to be active" These parameters (aio read size and aio write size) are not set by default in the smb.conf. The manpage implies that this would render the vfs_aio_pthread module...

Hi, I did use wireshark to verify that the client (window7) is not the problem, client is sending out multiple "SMB2 Create request" packets before he gets some answer. On the server side samba is processing this requests in a synchronous way, in order which they were send, that is what I see from strace output.

Is the ?important" vfs objects parameter documented in a man page anywhere? It appears in the man pages of several vfs modules, but never fully documented that I could find. Apparently it once was from a now dead link https://www.samba.org/samba/docs/old/Samba3-HOWTO/smb.conf.5.html#VFSOBJECTS <https://www.samba.org/samba/docs/old/Samba3-HOWTO/smb.conf.5.html#VFSOBJECTS> .

The directory is small, it contains only one file. stat() takes 15ms and if I read 1000 files it sums to 15 seconds. So the issue is really that open file is synchronous.

Yes you are

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,

...nformation can be found how to enable aio in samba 4. Initially, I would love to enable vfs_aio_linux. However, I cannot turn on the module and found out that the relevant .so is not built even I have tried "apt-get install libaio-dev" in my debian box. I have no way but turn to enable vfs_aio_pthread instead by the following smb.conf in the member server: [global] vfs objects = acl_xattr, aio_pthread aio read size = 1024 aio write size = 1024 The reading performance increases 30% in my test. I think it is worthwhile to amend it to the official how-to! And please tell how to build v...

If you're on Linux then use the module vfs_aio_pthread and set "aio_pthread:aio open = true" This makes open(O_CREAT|O_EXCL) calls async on Linux only (as it allows per-thread credentials). If it's opening existing files then this module currently doesn't help (although removal of a couple of lines of code would make it work). Are...
