Why is the owncloud 8.2 client slow to sync files?

Question

ubuntu

There is a system unit assembled on a GIGABYTE GA-C1037UN-EU mini-ITX motherboard (with an Intel Dual-core Celeron 1037U processor built into the board) and two gigabytes of RAM, Ubuntu Server 14.04 LTS OS with owncloud 8.2 installed there according to instructions off. site.
So, I have a problem with extremely slow synchronization of files from a computer connected to windows 8.1. Two and a half thousand files, with a total volume of 1.2 gigabytes, have been synchronized for 8 hours now and, according to off-client estimates, it will take another 1.5 days until the end of synchronization! There are no other running tasks on the computer, files are copied through winSCP at a normal speed for a 100 megabit network.
Well, yes, I understand that the processor is rather weak, but is it really not enough? Has anyone encountered similar behavior of owncloud?
PS: tested ubuntu server during sync. The processor is loaded at 8%, 4.5% of which is apache2, the network is loaded at 0.7%. It's all strange...

Answer 1

Look at the top and ipitraf load on ovncloud
And through the dispatcher at home

Answer 2

I have a system: GA-C1037UN-EU (rev. 2.0) did not notice such problems.
And by the way, you are wrong, the processor is one of the strongest in the line of this class.
View the system load, what "eats" the processor and memory the most? Perhaps the PC is performing some other tasks at this time.

Answer 3

Here is the output of the top command during synchronization,
it can be seen that the mysqld and apache2 processes occupy somewhere 6..7% of the processor time
PS: Strange, but the problem seems to be in the OS on the client. On the same windows 8.1, but under a different account, synchronization is performed at normal speed. I will sort this out.

Answer 4

Similar problem. ArchLinux both on the client and on the server, 100Mbit channel, ntp costs.
