How does the CPU limitation on Windows Server R2 Foundation work? – Server Fault


An impression many people get is that servers are static and inviolable. They are computers that are orders of magnitude more powerful than your typical desktop, and as such, they rarely if ever experience issues.

The reality is that servers are just big computers, often running specialized software. They can have all of the same sorts of issues that regular computers do, except they tend to be more regimented in their operation. More importantly, they can have just as many hardware and software issues as any other machine. A server running Windows Server R2 can have a wide range of configuration problems, settings that hinder performance, and even simple memory leak problems.

A fault in any of those components can lead to all manner of problems. Before you dig in, though, we recommend backing up your data and configurations. Note down any changes you make and when, so you can diagnose if those changes cause problems down the line. Power plans for servers dynamically scale the clock speed of the processors to meet the needs of the server at any given time. When load changes, this can cause slow performance and delays as the server adjusts. You can set the power plan per-device as a local machine policy, or for all of your servers as part of a group policy.

Either way, the option is found in the local computer policy menu under power options. In the command prompt, type fsutil 8dot3name query followed by your volume designation, such as D : — this will show you whether or not you have this option enabled. You can also strip existing names from compatible files, though doing so might not affect performance.

Your task manager shows, among other things, all of the processes running on your machine. Along with the process name, it can show additional information, including the RAM and CPU usage that process is consuming at any given time. A common cause of a slow Windows Server R2 installation is a process that is consuming exceptionally large amounts of resources.

First, check the bottom of the window. If so, you may have a problem. Check the Processes tab and sort it by CPU usage or by memory usage, to see which processes are taking up so many resources. If necessary, contact the employee responsible for the offending application. Servers are just as vulnerable to malware as personal computers. You will want to have some form of antivirus protection on your server. Usually, Windows Defender is good, but in some cases, you may need something more powerful as an enterprise-grade solution.

If you notice any odd processes consuming resources, or odd behavior, or signs of malware, scan for it. You should also routinely scan, as well as keeping active protection engaged at all times. Avoid making exceptions for individual users or applications, as these can be exploited. Also, keep in mind that some malware is insidious and difficult to spot. Not everything is an obvious piece of ransomware — the truth is, the worst viruses are the ones that are perfectly invisible.

It can also be an issue with DNS. Software issues are common, but you may also consider updating drivers for the hardware in your machine. Driver updates are often overlooked until they cause a problem, but it can be difficult to identify when a problem is caused by a driver issue.

The most relevant drivers to update are typically network card drivers, but graphics and other drivers can cause problems as well. As mentioned above, servers can be vulnerable to both malware and malicious attack from an outside source.

If your server is accessible at all from the internet, it can be subject to attack, even when the way to access it is hidden. Obscurity is not security. Attacks come and go. A lone bot spamming login attempts can slow down your server as it has to process those attempts. This is why implementing a lockout policy is always a good idea. Additionally, DDoS attacks can eat up server resources and slow down an entire machine.

Check network activity and look for unusual spikes or anything that might max out resources. There are many ways to protect a server against a DDoS attack, but it depends on the kind of attack. If you identify an attack, you can investigate further. Each packet of information passed between a server and a user or back is digitally signed to verify its authenticity. This helps prevent malicious users or devices from inserting themselves in the middle to scrape data or otherwise alter messages.

Unfortunately, in some cases, SMB packet signing can slow down a server, particularly with large file transfers. This is because each packet needs to be signed and authenticated, and this process takes time. Often, it can time out mid-operation as well, further delaying the transfer of a file.

You can check to see if this might be an issue by attempting to transfer a large file and watching the graph of progress. If it has abrupt peaks and valleys, time-outs may be the problem. You can disable packet signing in the security settings for your group policy. Be aware, however, that packet signing is a security measure.

Only disable it if you have other security measures in place to prevent man in the middle attacks. Over time and with use, a hard drive — particularly spinning platter drives, though SSDs can have issues as well — degrades. This degradation can result in corrupted blocks of storage, which may or may not be otherwise occupied. Servers can run into issues if system files or other infrequently-accessed files are corrupted, making certain processes error or time out. Sometimes this results in hard-locks or system crashes, and other times it simply causes a time-out or other process failure.

One way to check for such errors is to use the System File Checker. If it finds any, it will offer you the option to repair them, which should help resolve the issue. If your system file scan found faults, you might have a drive that is on the verge of failure.

If this is the case, you should consider scanning the entire disc to look for other faults, and repair them. Then, you should swap out the drive. If your drives are properly mirrored, you should be able to hot-swap an individual drive without causing issues. There are approximately a million different settings within the overall Windows Server R2 system that can be tweaked to improve performance.

Often times, the standard settings out of the box are good enough, but in some situations they are no longer adequate. You can tweak and tune these settings to improve the overall performance of your system. You can find the full guide in PDF form here. Tweaking and dealing with system issues is a core part of running an on-premises server infrastructure. Remote assistance can diagnose a lot of potential issues with your server, and we can both offer assistance with fixing them and with managing the servers moving forward.
