something off the records about owncloud performance.

[richhl]

sorry this is not properly an issue but i have not find a more proper channel to ask you.

i'm evaluating owncloud and have reviewed your tnc2014_slides_TNC2014ScalingTheUnscalable.pdf and this...owncloud/core#7072

a little scared about performance. any advice? i'm thinking about going seafile

thx a lot

Define what you are worried about exactly.

Currently we run with 3050 users (adding around 30-50 daily) and 3.7TB of data in 3.45 million files. All of that on a dozen virtual machines, the largest one being the DB server (32 Gig RAM, 16 cores)

The DB server still has around 60% idle time, the NFS server (that I was most worried about) is holding up nicely so far (its performance is similar to when we only had 100 users)

As for client / syncing performance: Yes - ownCloud 6 isn't very fast, on our test system with oc7 we have seen 2-3 times sync speed. The problem is mainly that oC handles many small files really poor - that has not improved significantly between releases.

Most of our users seem happy though.

Thx for you feedback...

your 34th slide "1 Upload 180 SELECT?"

and the github thread talking about extremely slow client performance:

Ok, so I tested to upload through the servers Web GUI, and the problem of slow uploads appears there as well. And surprisingly it´s equally slow as uploading trough the client.

"So in other words, the problem is on the server side as well.

@enoch85 Indeed, the long delay until each file upload starts is due to processing @ the server (at least IMO)."

thx

yes - definitively a problem in the server code that takes a long time for each request. The 1.7 client uses parallel uploads and that improves the overall syncing speed, but the bottleneck is still the server handling each file upload (and putting stuff into the database)
