Samba Transfer Speed Improvement

twl · 2011-06-02 21:36:06

My samba transfer speed from my linux installation to and from my windows 7 box was always pretty slow. It was about 40MB/s or so.

However after adding this one setting to my [global] smb.conf, my speeds more than doubled. Im getting ~110MB/s read and write to the linux samba share.

"strict allocate = yes"

Seeing the benefits has some requirements though. Here is the documentation http://wiki.samba.org/index.php/Linux_Performance

Took me a while to find this setting. Theres a lot of other tweaks I found that didnt offer near the performance improvement that strict allocate did.

I didnt see this on the samba arch wiki but maybe it'd be a good idea to put it there? (https://wiki.archlinux.org/index.php/Samba)

Anyway, hope this helps others

Yes, if it's such a performance booster, maybe it's worth mentioning in the Wiki. There has to be a reason as to why it's turned off by default, though, as it seems too good to be true...

@op - you can modify the Arch wiki page if you feel there is value to documenting this setting. I would encourage you to do so. The Arch-community is one of the reasons why Arch is a great as it is today!

How did you measure?

dstat on arch and windows 7 transfer window

Sorry, I wasn't clear enough. I'm not saying about measurement tool. I mean which operations were used - smbclient get and put, or something else?

On my windows 7 machine Just browsed some of my shares that were exposed by samba server on arch. I'd then try transfering some large linux .iso's to my windows 7 pc (to test read) and then write them back to the arch server (to test write)

so I think thats get/put?

Thanks for the clarification. I just was interested in the case when both - client and server - are running under Linux:
