Now I have another bad problem, that is, the download speed of my NextCloud on the Intranet is not very ideal, of course, excluding the blocked physical lines and network cards, it seems to be less than 50M/s, which should be able to reach 100M/s under gigabit network environment, so NOW I don’t know where the problem is.My upload can reach 70M/s+
Could it be that you have slow Disks in your server?
No, my server disk and my computer disk are SSD, physical speed limit basically ruled out
Okay thats good, could it be that the port on the router with which you connected the Server is in energy save mode?
