Re: [Moosefs-users] How fast can you copy files to your Moosefs ?

[Chen, A. <alv...@in...>]

I mean setting goal to 3. If setting goal to 1, the writing speed is 9MBytes/sec for 100Mbps networking, but if setting goal to 3, the speed is just 500KBytes/sec.

For 100Mbps networking, the speed should reach 12.5Mbytes/sec, so if setting goal to 1, 9Mbytes/sec is reasonable, but if setting goal to 3, the speed should be around 3Mbytes/sec.

By the way, I just use scp to copy 4GB data file to the mount folder.

First of all if you want better performance you should use gigabit network.

We have writes of about 20-30MiB/s (have a look here: http://www.moosefs.org/moosefs-faq.html#average).

You can also have a look here: http://www.moosefs.org/moosefs-faq.html#mtu for some network tips.

PS. Talking about 3 copies do you mean setting goal=3 or copying 3 files simultaneously?


Kind regards

Hi guys,

I am a new user of moosefs. I have 3 chunk servers, one master server with 100Mbps network. And I just copy a 4GB files from one client machine to Moosefs, and the copying speed can reach 9MB/s if just one copy, but the copying speed is just 500KB/s if 3copies.


How fast do your Moosefs can reach? Does anybody get better performance?
