Server 2012 incredibly slow

I have a Dell Precision T7400 that I use as a backup file server installed with Windows Server 2012. I'm not expecting fast boot times with 2 RAID controllers, so that's not my issue, but the slowness lies with the behavior of the OS itself. If i'm doing
simple things like backing up files, and I try to launch Firefox while doing that, Firefox takes about 3-5 minutes just to load. I have tried IE, but that just crashes immediately upon launch, and that takes even longer to load. The server doesn't have too
many roles, so it should be this slow. The hardware I have is as follows:
1x E5420 Quad Xeon 2.5Ghz | 4GB Buffered RAM | 1x Nvidia Quadro FX1700 512MB | PERC 61 RAID controller + internal RAID controller | 500GB 7200rpm boot drive on internal, 2TB 7200rpm + 1TB 7200rpm using RAID 0 on PERC
I thought 4GB would have been enough to run a file server and its basic functions, but is this not true? What else could it be?

So when we start talking performance we have to take the entire system into account.
Under 2012 if you open perfmon, Navigate to System Performance, then click the run button
That will take awhile and you should do that while it is having performance issue.
It will create a report under the reports folder
Software that you have installed on the server also has an effect on overall performance. Things like endpoint protection and antivirus can have a big impact.
Some antivirus can become overly aggressive with the scanning of files as they are being read from or written to disk, inbound on the network card and outbound on the network card.
Raid card configuration can have an impact as well based on how the onboard raid controller cache (if any) is setup (2 settings that come to mind are the adaptive read ahead and write back)
Another thing to note about caching, some of Windows Roles and Features will disable the cache on the system partition. Active Directory, DFS, DHCP, SQL and pretty much anything that utilizes a jet database. This is a performance hit but will save your data
on a power outage.
If IE crashes on launch, that does not build confidence in the install or applications that may be running.
You can do a clean boot http://support.microsoft.com/kb/929135
Follow the Windows 8 instructions as that's the same for 2012.
Hopefully that helps.

Server 2012 R2 slow performance over all

This is a DELL PowerEdge R820 / 256GB RAM / 4TB onboard storage configured as Remote Desktop Services Host /TS... running QuickBooks, MS Office 2010 STD, Symantec EndPoint Protection (basic antivirus installation ONLY)... 1 month old server... SUPER fast,
super powerfull.... Part of an AD in SBS 2008 Premium... single NIC card 4 ports / 3 ports disabled. single IP... no VLANS... server is able to resolve ANY pc, DNS record with no problems... able to resolve DC by name, able to receive GP, able to update, able
to do everything that I can think of.... EXCEPT... anything I open, word, excel, QuickBooks, IE.... takes forever to open... after the application is open is fast but to open anything takes 3-4 minutes.... open ticket with Symantec all looks good, created
lots of exceptions for antivirus/real time scanning, open ticket with QuickBooks: files look good application was removed and reinstalled to be sure all was done correctly... check the binding order for the disabled NIC; the active one is TOP option, no errors
at all in event viewers for system, application, setup, no errors at all in DELL management tool, no hard drive errors, no controllers errors.... this server is replacing an old dell poweredge 2008 STD with 24GB RAM... the old DELL opens the same applications
way faster than the new one... same Quicken version; old server opens Quicken in seconds, new one 3-4 minutes..... Real time monitoring NEVER goes above 1% for CPU and 3% for memory utilization.... one more thing... removed antivirus 100% restart... same performance
without antivirus.....
Any ideas will be great as of how to troubleshoot the slow performance....
Thank you!

Hi,
As Sam suggested, please check if there any issue occurred in hard drive.
On current situation, please also refer to following steps and troubleshoot, then check if we can find more
clues.
Please check if you have installed all necessary updates for the Windows Server 2012 R2.
Please
perform a clean boot to check if there has software conflicts.
Please use Resource Monitor to troubleshoot and check if we can find some more details.

Windows Server 2012 very slow performance executing files

Hello,
I am running windows server 2012 as dc with 2 clients connected running win7 pro x64, this is a new setup.
Whenever i try to open a large file from the client or an application from the client it takes forever to startup or to load. The performance monitor indicates a maximum workload of 15% at all times.
I have tried all the following potential solutions i found, however none of them seem to do the trick.

Windows server 2012 standard - slow performance in file sharing

I recently installed two windows server 2012, one is for DC, one is for File Sharing; it works fine in the beginning.
Lately, it comes a problem, every once a while it is very slow when opening a file on the server from a client PC; but when i restart the file server then it will be fine again.

Hi Simon,
Based on your description, how is the workload of the file server?
Before going further, regarding slow network performance when opening a file that is located in a shared folder on a remote network computer, the following article can be
referred to as reference.

Server 2012 extremly slow

Hi!
Just installed MS Server 2012 R2 Standard 64-bits on a HP Pro Liant 380p host. When trying to connect the network cable to the network and domain the GUI becomes extremly slow (can't drag the mouse without waiting for some seconds or open windows). We
have no indication on the preformance meters and need to unplug the cable to be able to use the GUI. Anyone have a solution for this problem?

Hi
I would suggest getting up to date drivers for the machine. Also check the event viewer on what is failing.
how much ram do you have in the server?
Hope this helps. Please remember to click “Mark as Answer” on the post that helps you, and to click “Unmark as Answer” if a marked post does not actually answer your question. This can be beneficial to other community members reading the thread.
Drivers is up to date, event viewer gives no information and it's 96GB RAM installed.

Windows server 2012 R2 Slow RDP

Hi
I have server 2012 R2 Datacenter installed on HP Proliant 380 G8. All drivers and firmwares are updated and confirmed by HP. The machine is quite powerful with hundreds of gigs of RAM.
When I RDP into the machine, The screen hangs on "welcome" screen for a good 10 seconds. Same hardware with server 2012 Datacenter is much faster. It is also fast with 2008 R2.
I deployed 4 servers so far and all have the same issue.
Has any one experienced this slowness before?
I appreciate any help.
Thanks

Hi Atif,
Thank you for your posting in Windows Server Forum.
First of all please try to provide TP’s answer. In addition, what’s the version of client OS and RDC? If you are using Windows 7 then use RDP 8.1 for better performance. Apart from this, try to DisableTaskOffload in the IP-parameters. For more information,
kindly go through beneath article.
Performance Tuning Windows 2012: Network Subsystem–Part 1
Also try to configure below setting, might helpful for your case.
On the server:
Computer Config > Windows Settings > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections > Select RDP transport protocol = Use only TCP
On the client:
Computer Config > Windows Settings > Admin Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client > Turn off UDP on Client = Enabled
Hope it helps!

Mac Mini 2012 incredibly slow

Hi everyone,
I'm trying to fix a Mac Mini (late 2012 model) for a familymember. He bought a used Mac Mini and it looks good on the outside, but something seems to be wrong inside. Now, I'm great with computers but relatively new to Apple hardware, and so I turn to all of you for some help.
The symptoms:
- Mac Mini loads everything insanely slow. It's like a handicapped snail.
- Very random boottimes, sometimes it boots in 40 seconds, sometimes it takes 5+ minutes.
What I've tried:
- Checked the harddrive with the Disk Utility. The test returns no problems. The SMART status is also listed as verified.
- Ran a speedtest on the harddrive to see if its performance is below expectations. Results were around 100MB/s sec write and read speed.
- Ran the Apple Hardware Test: no problems detected.
- Formatting the harddrive and reinstalling OSX 10.8 Mountain Lion. Faced lots of problems during installation, had to start over three times (confirms it as a hardware issue for me).
Now, I'm thinking the harddrive is dying but all the tests show it's just fine. Any suggestions?

Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Windows Domain Controller on Windows Server 2012 R2: Hyper-V roaming profiles not loading due to slow connection

I have racked my brain and done everything that I know to do for about two weeks now. I am setting up a new system at our fire department and I am having the worst luck with getting the workstations to login to the domain controller with roaming
profiles. It keeps telling me that the roaming profile could not be loaded because of a slow connection. These are workstations that are connected directly to the switch that the DC is connected to. I have tried multiple connections regarding
the layout (DC into the router, router into the switch). The router is a Cisco RV220W. I have two VLANS, one for public and one for private domain. The Private VLAN has DHCP turned off since I am providing it through the DC. I currently
have a connection from the Private VLAN going to the unmanaged switch that the workstations and server are plugged into.
The server is a Dell PowerEdge R420 that has 6 NIC ports (1 dual port and 1 quad port). I have a virtual switch setup on Hyper-V for an external port (let's say Card 2 Port 3) that is assigned to the WS 2012R2 Domain Controller. The DC can see
the internet fine and the workstations can connect to the shared folders on the server. I can retrieve files by just using the computer name or FQDN. The DC is also running DNS and DHCP. The DNS has the _msdcs setup from when I installed
the active directory role. I have attempted to assign static IP addresses to the workstations:
IP:                     10.0.0.80
Subnet:             255.255.255.0
IPV4 Gateway: 10.0.0.1
IPV4 DNS:        10.0.0.12
I've attempted "append the specific DNS suffix", I've "registered the connection in DNS", I've used "use this connections suffix in DNS registration".
The server is assigned:
IP:                     10.0.0.12
Subnet:             255.255.255.0
IPV4 Gateway: 10.0.0.1
IPV4 DNS:         10.0.0.12
The DNS entries have forwarders that forward to my ISP DNS servers for lookup
I've enabled and disabled DHCP, I've installed a new VM just to create another DC to make sure that I didn't goof up when I created it.
I've lost my patience with this project and am sinking fast. Can someone please offer some advice as to what I've done wrong? I've created this exact scenario at work many times but, I've never done it with Windows Server 2012. Is this
possibly something to do with the Dell PowerEdge server (Generation 12) with the SR-IOV? I am going to attempt to work on it some more tomorrow when I get over there. I think there may be an issue with the SR-IOV not being enabled on the machine
through the Dell Bios. Would the SR-IOV really cause the workstations to report a slow connection? When I login at the domain controller the roaming profiles and folder redirection work fine so, I know the GPO settings are correct. I don't
have "ignore slow connections" or any of those GPO's set. I need to get it working the correct way so, I didn't want to fool the server when there is another underlying problem. Any help that someone can offer, I am more than willing
to listen. If you need more information, please ask.
Thanks,
Jay

So, I've managed to research this some more since Thursday and I've come to the conclusion that Hyper-V does a horrible job of supporting Qualcomm NIC cards. That's the only thing I can conclude as far as where the issue is originating. I've read many
post and walkthroughs but nothing that has helped. The issue wasn't with any settings in the domain controller. The issue was that there really is a slow connection originating at the domain controller that is a VM and has network connectivity through the
virtual switch from Hyper-V. So, next question is, how do I get the DC to have better connectivity through the NIC that Hyper-V won't give it? If hyper-v would allow passthrough, this would be so much simpler. VM-ware is looking really good at this point.
Im disappointed in MS right now.

Boot up of Windows Server 2012 Essentials seems slow (extended Please Wait screen) and there are errors in Health Report

Dear Sir or Madam,
I have been experimenting with the evaluation version of WS2012e trying to get the installation and subsequent build into an optimal set up, and once I have everything I want it to do mapped out, I'll set it up with the full version with using the key that
I bought.
However, I've noticed that the server seems to experience a delay during cold boot - it sits with a Please Wait screen for about 60-90 seconds before it presents the screen with an option to Log on. I have also discovered from running Health
Report, that there are some entries in the event logs which appear to coincide with start up times, and which seem to be interconnected to each other in the issues they are describing, and I have copied an example of one of those health reports below.
I assume that everything sorts itself out in due course, because the events say the process will be re-attempted and these errors don't repeat again after the system has booted up. I also have the server set to suspend when not in use with the Lights
Out add in, so it shouldn't need to cold boot often - but I wondered if there's a way to correct these errors so that they don't hold up the boot up process? I'm also concerned that these errors will cause me later problems with storage pools and
the like at a later date - the disk replication one seems particularly worrying. Alternatively, are these errors just a normal part of the start up process - the timing of when different processes start relative to each other - and can be safely ignored?
In trying to understand what the events describe, I thought that WE2012e acted as its own Domain Controller, and yet it seems from the event log entries that it is waiting for another server to respond to AD / DC requests (but there isn't another server
on my home network). The other thing I remember from when I first tried out WS2012e, is that it took control of DHCP or DNS from the router, and I found that frustrating when waking up my laptop and it wouldn't connect to the internet until the server
had fully booted up and re-asserted its network settings. Is this another symptom of the same problem? I remember seeing a posting at the SBS Diva's site about how to update the server so that it gave connected PCs a backup option for connecting
to the internet when the server wasn't available, and was going to try to find that again to see if that helped.
By way of background - there isn't another server in my home network. This is an attempt to do a clean install onto the same hardware that I ran the initial trial of WS2012e, now that the trial has expired, so I'm not trying to migrate from an existing
server. I moved all the data on the trial server off onto an external disk, with the intention of importing it back once I had the Storage Pools set up the way I wanted on the new build, and since I didn't want to keep anything else about the server
trial. Am I correct in thinking that I don't need to go down the Migration route during installation, and can go through a Clean install in this circumstance?
I'm running on an Asus P8-H77-i motherboard, with an i5-3470s CPU and 16MB RAM, and I have WS2012e installed on 256Mb SSD formatted under GPT with uEFI boot - the latter being the main reason for the reinstall, instead of just giving the Evaluation
version the new key on the original MBR set up. I've also enabled Intel Rapid Storage and Rapid Start - and successfully set aside the hibernate partition on the SSD - but discovered that this is about forcing a hibernate after suspend, allowing
the system to power down until its needed again, and then resuming from hibernate on the SSD rather than cold boot each time. That seems to work, but doesn't improve the cold boot times at all, which was what I was hoping for - ideally the way my
laptop will boot from cold in a few seconds into Windows 8.
Yours faithfully,
Avon

Serial Port communication very slow in RDP on windows server 2012

Hellò, we have installed a new server 2012 and connected some thinclients via RDP, since that moment all peripherals connected to the imported com ports of the thinclients are running very slow, for example the cash register issue any receipt only after
15-20 seconds!!. We have try to connect via RDP also a personal computer with many other OS like windows 8, windows 7, or XP but the result is the same: 15-20 seconds for a receipt!! We solve the problem only changing the server 2012 with a old server
2008 or 2003!. How is possible window server 2012 is so slow on RDP imported com ports??. There is something to set for speed up the com ports on rdp? For us this is a great problem, all of our customers are using cash register via RDP and they can't wait
all this time for a receipt. For your information we have tried to connect the cash register to the same com port of the same thinclient to the same server 2012 without RDP and the issue of the receipt is fast, so the problem is something on RDC of the new
OS windows Server 2012. Also note this is a bi-directional communication because the cash register use a bi-directional communication for printing each one of the voice on the receipt, this problem wll not affect other printers unidirectional where the
print process starting in less one second. Please help us to solve this problem, otherwise we will not more install windows server 2012.

Hi,
Thanks for your posting in Windows Server Forum.
When the slow performance issue occurs on server 2012, check the Windows Logs – Application category of the Event Viewer (eventvwr.msc) on both the client and server sides. If there is any logs recorded, please let us know them. Please also check the
driver is properly installed on server and check the compability guide with the cash register machine, whether it support server 2012 with remote session. If there is particular requirement then you need to solve them first.
In addition, would like you to try connecting with RDP 8.1 and check whether it faces same issue.

Windows Server 2012 Storage Spaces Simple RAID 0 VERY SLOW reads, but fast writes with LSI 9207-8e SAS JBOD HBA Controller

Has anyone else seen Windows Server 2012 Storage Spaces with a Simple RAID 0 (also happens with Mirrored RAID 1 and Parity RAID 5) virtual disk exhibiting extremely slow read speed of 5Mb/sec, yet write performance is normal at 650Mb/sec in RAID 0?
Windows Server 2012 Standard
Intel i7 CPU and Motherboard
LSI 9207-8e 6Gb SAS JBOD Controller with latest firmware/BIOS and Windows driver.
(4) Hitachi 4TB 6Gb SATA Enterprise Hard Disk Drives HUS724040ALE640
(4) Hitachi 4TB 6Gb SATA Desktop Hard Disk Drives HDS724040ALE640
Hitachi drives are directly connected to LSI 9207-8e using a 2-meter SAS SFF-8088 to eSATA cable to six-inch eSATA/SATA adapter.
The Enterprise drives are on LSI's compatibility list. The Desktop drives are not, but regardless, both drive models are affected by the problem.
Interestingly, this entire configuration but with two SIIG eSATA 2-Port adapters instead of the LSI 9207-8e, works perfectly with both reads and writes at 670Mb/sec.
I thought SAS was going to be a sure bet for expanding beyond the capacity of port limited eSATA adapters, but after a week of frustration and spending over $5,000.00 on drives, controllers and cabling, it's time to ask for help!
Any similar experiences or solutions?

Windows Server 2012 HyperV VMs becoming extremely sluggish and slow

I have recently set up a new system for a client consisting of a single Dell T320 server with Xeon E5-2350 2.2GHz 6 core cPU and 32GB of RAM. Windows Server 2012 Standard is installed on the bare metal, and runs only the HyperV role. It is not
joined to any domains.
It hosts two VMs, one a Windows Server 2012 Standard VM containing the RDS related roles acting as remote desktop server, with 10GB RAM allocated and 3 cores. Only 5 people use the terminal server concurrently.
The second VM is a Windows Server 2008 R2 based primary domain controller, with 16GB of RAM allocated and 3 cores. It runs the AD role, as well as Exchange and GFI MailEssentials 2012. Avira is also installed on this VM.
The problem is that the system will function properly for 3-4 days, then suddenly it goes into a state where a multitude of applications would start consuming inordinate amount of CPU time, and become very, very slow. Almost like the hypervisor goes
into a software emulation mode where everything runs like molasses. This affects BOTH VMs equally. For example, Exchange and GFI on the Windows 2008 R2 VM together consume about 25% CPU, most of it is spent in kernel CPU time. At the same
time, in the other Windows Server 2012 VM, svchost, Taskmgr, WMIPrvSE, LogonUI, Explorer, sqlservr, wsmprovhost etc. will all consume a total of about 70% CPU time, this time 99% of this is user time, not kernel time. When one user starts any application,
be that internet explorer, firefox or TaxPrep, the CPU spikes up to 100%.
All while nobody is using the system, the system is idle and no mails are flowing in or out of the system. A reboot of the VMs does not fix anything, even a reboot of the host server does not fix anything. When I yanked out the two power supplies
and performed a hardware diagnostic (which came back 100% OK), it booted up and the slowness was gone for 3 days, until today when it started acting up again like I described above.
One more thing, when the system behaves normally the sunspider javascript benchmark in IE10 takes 316ms to execute (average) on the HyperV host operating system. When the system goes slow like this, I pause the two VMs in HyperV then run sunspider
again, only to be greeted by an average time of 5084ms. So this clearly does not only affect the virtual machines but the host operating system as well. My gut still tells me the hypervisor is getting messed up somehow.
Any ideas? This is a major problem and I have no idea what is causing it.

We have had the EXACT same thing happen with a Dell T320 on two separate servers. The first one was running SQL Server 2008 with nothing else funny going on. It ran fine for a month or so, then it developed this slowness issue. We finally installed SQL on
a loaner box (without Hyper-V) and it worked fine. We brought the T320 back to our shop and tested the hell out of it with Dell's assistance and it was NTF. Took it back onsite and moved an SBS 2011 VM over to it. After a few days, it ground to a halt. CPU
utilization was 100%. I started shedding services, killing Exchange, Sharepoint, etc. Even stripped to the essentials, the CPU was still up in the 60-70% range.
I put a T310 out onsite and downed the guest SBS vm. I copied the HUGE vhd over to the T310 (running Server 2008r2 with the Hyper-V role) and it ran perfectly. CPU at about 2-4%, spiking to 15% occasionally.
We finally concocted a story that the USB controller was bad, so they replaced the motherboard (not the CPUs) and it all seems to be working OK now after we sunk at least 100 man-hours into the problem.
Our second one is a similar setup. T320, Server 2012, Hyper-V role, SBS 2011 Standard and a couple of member servers running basic apps. No one can find any problem and everyone acts like this is something new, although my posting comes one year after Tim's
original posting.

Windows server 2012 R2 PXE boot is unworkable slow, I have this exact same set-up working in 2008 R2 What can I do?

Hi there
I'm trying to deploy a windows 7 image through Windows deployment services via PXE boot from a 2012 R2 server.
Issue: PXE boot is extremely slow, it takes up to more than 60 minutes for the device to download download the PXE boot
Things I already tried to get this up and running:
I've tried to change the TFTP block size via command prompt and via regedit
I've changed the settings on the tab of the WDS role (go to WDS role -> properties on server -> Tab "tftp")
Both actions resulted in PXE boot being even slower than it already was.
To make sure this is not because of our environment I’ve set up the same configuration on a windows server 2008 R2, here PXE boot image is downloaded to the machine within 3 minutes.
Both servers are set up through Hyper-V this is the configuration:
2008 R2:
Memory: 4096 MB
1 Virtual processor
IDE controller 2 hard drives
Network adapter
2012 R2:
Memory: 4096 MB
32 virtual processors
SCSI controller 2 hard drives
Network adapter
I can’t imagine that PXE boot is not working because of the differences of the Hard drives controllers or because of the amount of the virtual processors.
Windows server 2012 R2 seems to handle PXE boot TFTP differently in comparison to 2008 R2.
Do you guys know what I can do/try to get this working?

Hi Jacques Rodrigues,
You can run Windows Deployment Services on Hyper-V virtual machines,
that the performance will often be degraded, particularly during the Trivial File Transfer Protocol (TFTP) download phase. This phase is very resource-intensive and may
fail if insufficient resources are available on your server running Hyper-V.
If you are using multicast, Check if IGMP Snooping is enabled i.e. Routers that support multicasting. In particular, Internet Group Membership Protocol (IGMP) snooping should
be enabled on all devices. This will cause your network hardware to forward multicast packets only to those devices that are requesting data. If IGMP snooping is turned off, multicast packets are treated as broadcast packets, and will be sent to every device
in the subnet.

I’m glad to be of help to you!

New Server 2012 R2 virtual servers seem slow, how to tell if it's Windows or underlying VM host?

We recently created two virtual Server 2012 R2 boxes, but the server seems rather pokey on a Remote Desktop session to it. Task Manager doesn't show high processor usage (it reports 2.26GHz, 2 sockets, 4 virtual processors, virtual machine yes, L1
cache N/A", memory is usually around 11%, and not a concerning amount of network traffic.
Since both servers are pokey, I'm thinking that the issue may be in the VMware side, or the hard drives this is running off of are slow, or something not at the OS level. But how can I confirm that, or at least say that without a doubt it has nothing
to do with Windows?

Hi RJO22,
>>Task Manager doesn't show high processor usage (it reports 2.26GHz,
2 sockets, 4 virtual processors,
It seems that the VM spanned two NUMA nodes .
Is there any other VM show the processor usage ( 1 socket ) ?
Best Regards
Elton Ji

I looked at another virtual server we have, and it shows 2.226/2/4 just like that one. Is that bad or does that cause performance issues with how mine say 2?

Wsus 6.3 - Server 2012 R2 - Update downloads very slow - no proxy is use

I have WSUS 6.3.9600.16384 installed on Server 2012 R2 and downloads are very slow, < 500 Kbps.
A proxy server is not in use and updates are downloading, but very slowly.
Plenty of BW available, consistent 60 Mbps internet download speed test results.
Current download setting is set to "on approval".
Has anyone had a similar problem and hopefully found a solution?

Download operation is successful so I do not believe there is a problem with HTTP 1.1. range requests through my firewall. I would have tried KB anyway but none of the "*SQL.EXE" programs are on my 2012 R2 system so I was unable to try it.
