Why is nextcloud slow?

Question

System administration

Please tell me how to increase the speed in the nextcloud download / upload over the network. On a test machine connected to 1Gbit, it gives a maximum of 30MB/sec for writing, and 60MB/sec for reading.

Answer 1

Well, first you need to define what low speed means, and what limits it.
Your channel is 1 gigabit.
So, theoretically, it can be pumped through it in the region of 120 megabytes / s.
Practically less - depends on network settings, type of traffic, protocols used.
In addition, the channel can be loaded.
In general, the normal transfer rate on average for a gigabit channel is 50-60 Mb / s.
Your values ​​are like this.
It should also be understood that you are not just driving traffic, you are reading it from a disk - not every disk will be able to give out the same 30mb / s in any situation.
It all depends on the load, the size of the accesses, the ratio of writes to reads, the size of the cluster,
Therefore, determine what speed you need, how real it differs from the desired one.
And then you can already think what exactly is worth doing.
