Synchronization is slow!

Postby sh1ntqr0 » Thu Apr 07, 2016 8:25 am

Dear Sir,
I have some questions about ownCloud synchronization speed.
Could you help me provide the following info.

I'm using this desktop sync clients(application) for Win and Mac in my office.
I think that files that other people have uploaded are not synchronized immediately, but I don't understand the reason.
Those file sizes are small.(For example, the total size is 21.9MB, all 224items, each 6kb)
We have done the network speed test, but it seems that the network is not too slow to sync, but it takes about more than five minutes...

Is there any method to sync quickly?
Please tell me if you know.

Thank you.

Best regards,
Sh1ntqr0

Hi,

there are various issues/bugreports about slow file sync when using small files available:

https://github.com/owncloud/client/issues/331
https://github.com/owncloud/core/issues/20967

From user-side you could only make sure that you're not using SQLite, that you're using Redis-based file locking and that your system is performance optimized. I could post some links to the documentation later if needed.

Dear RealRancor.
Thank you for reply.

I'll try it that use Redis for file locking.

I make comparison between my setting and general performance tuning.
What points do you think I should pay attention to?

Thank you.

Best regards,

During uploads, it can be helpful to watch the processes on your system. Use top to identify the processes consuming all the CPU power, and iotop to monitor the file operations of individual processes.
