reDDevil Posted February 28, 2021 Share #1 Posted February 28, 2021 (edited) I successfully installed DSM 6.2.3-25426 with 1.03b loader onto my HP EX485 MediaSmart server but after SHR pool was created from my 3x Seagate 1TB disks I noticed extremely very slow read speed from the NAS. Windows shows 350KB/s. Downloading a file of 200Mb from NAS to desktop takes 34 seconds. The writing speed is good around 2MB/s. I have 1Gbit LAN and never had such speeds. The read speed from another NAS in my network is 2MB/s. Where to dig? Edited February 28, 2021 by reDDevil Quote Link to comment Share on other sites More sharing options...
Mary Andrea Posted March 13, 2021 Share #2 Posted March 13, 2021 (edited) Hummm, when it happen sure there are some wrong into DSM starting. When it happened to me, and suddenly drop down DSM operation, I ve check all new apps, I tried to uninstall some apps, delete folders and volumes unless , reset once, twice , and if slow performance continue ... reinstall DSM again .... Moreover , I found that its better create a small Volume1 for Essential Soft (apps , virtual machine,etc) on SSD or small HDD, is faster, Volume 2 whit 3.5HDD is better for Big Data , and , if you have possibility to have a SSD Cache, all system became fluid and fast.

Fratscha Posted March 15, 2021 Share #3 Posted March 15, 2021 (edited) I also did encountered slow read speeds about 2mbyte/sec inside of a gigabit network. Turned out to be the MTU. Did switch it to 9000, and now the speed is where it should be, around 110mbyte/sec.
