I have a problem with significant slowdown in writing and reading files on Windows Server 2012, the equipment is HP ML350p gen8. Accounting, payroll and spreadsheet programs have a very big problem with reading and writing files. It's probably related to updates or it's just a coincidence.
I turned off the firewall
I uninstalled WithSecure Elements EPP
I entered it into regedit:
NtfsDisableEncryption 1
DisableLeasing 1
EnableOplocks 0
These settings didn't work
The problem after the restart is that it does not give me the Domain network right away and the public network, I change it manually using the PowerShell command: simply restart the network interface.
Ping host to server is suspicious

xcopy . \Server\files\DB\ very slow
The disks in the controller show without errors
I will rule out a network failure over the weekend, switch the server to another switch and one host, and then I will test it. For now, I have transferred several databases to another computer.
Please help me, what else should I do, reinstall the network card, maybe something with SMB, I don't know...
best regards SW
Maybe that's where the problem lies...

Isn't this sometimes too much value? I'm not sure if I'm counting correctly...
0000000047ac0000 this hexadecimal 1202454528 / (1024*1024) = 1146,75 MB Raid5 -> 3 SaS 15K/h. full capacity is 1200GB allocated 25% read to 75% write in P420i controller.
Maybe I don't have too much cache, physically it shows 1.09GB, physically the disk is 60% full...
does anyone have any ideas?
best regards SW
I checked the entire network, isolated the server on a small gigabit switch with one host to check the transfer speed and still the same. By the way, I replaced two disks with larger ones in raid one. and I added some memory and put new thermal paste on the processor. Could someone tell me what to check to find any problems or reasons for the slowdown? I suspect a network card, maybe raid 5 disks, maybe a problem with the cache of these disks, maybe the controller, or incorrectly assigned permissions, I don't know...
best regards SW
PS.
I have one more question: how to check these versions?
