![]() You can read more about the different versions of the. Future releases will contain even more improvements so be sure to always check for the latest available version. It should also be noted that 4.5.2 is the latest version as of the publishing of this blog post. You can save yourself a lot of trouble by upgrading to 4.5.2 as soon as possible, if you are not already there. We've seen more than a few of these in support. There have been multiple performance related fixes from version to version, some of which impact Exchange 2013 fairly heavily. However, I would strongly recommend that 4.5.2 be the default choice for any Exchange 2013 installation unless you have very specific reasons not to use it. All of these versions are supported on Exchange 2013. I will however touch on a few of the high points.Įxchange 2013 runs on version 4.5 of the. I'm not going to duplicate everything in the article here, I would suggest that you read if you are interested in this topic. This was actually the main motivation for a TechNet article we recently published called Exchange Server 2013 Sizing and Configuration Recommendations. Those of us that have worked enough performance issues start by following a list of things to check first. Therefore, I will not be covering Exchange 2010 in this post. NET Framework, and different implementation of. Some of these include completely different megacycle requirements, different versions of the. There are some fairly significant differences between Exchange 2010 and Exchange 2013 that change the best practices and troubleshooting methodology. High CPU issues across versions do have some things in common, however much of the data in this article is specific to Exchange 2013. Are you experiencing a problem, are databases inadequately balanced, or is the server just undersized? What about a 100% CPU condition? Does it happen for 10 seconds at a time or 10 minutes at a time? Does it only happen when clients first logon in the morning or after a failover? In this article I'll go into some common causes of high CPU utilization issues in Exchange 2013 and how to troubleshoot them.Īt this point I should note that this article is about Exchange 2013 specifically, not earlier versions. For example, say you consider ‘high’ to be 75% of CPU utilization during the day. What exactly is high? How long does it occur? When does it occur? All of these are questions that have to be answered before you can really start getting to the cause of the issue. "High CPU" can also be a bit of an ambiguous term as well. One of the most common performance issues we see are ones where the CPU is running higher than expected. This can manifest itself like anything from random client disconnects to database failovers or slow mobile device syncing. Part of the reason for that is the ambiguity of the term "Performance Issue". Few of them can be more difficult to troubleshoot than performance issues. We discovered similar results on the last generation Surface Pro 6 and even Surface Pro 5 and the latest Surface Pro 7 appears to be no different.In Exchange support we see a wide range of support issues. While this looks good on paper, the steeper throttling can be off-putting to performance users. After accounting for the throttling on both devices, users can expect a 22 percent deficit in processor performance on the tablet relative to the Surface Laptop 3.ĬPU throttling is not uncommon on tablets, but it's particularly noticeable on the Surface Pro series since Microsoft insists on equipping its flagship models with the same Intel U series processors as found on larger Ultrabooks. The tablet eventually stabilizes at a nearly 30 percent performance dip from its original score. 780 points) only to degrade faster and steeper over time on the Surface Pro 7 tablet. Performance starts out relatively the same between the two systems at the beginning of the run (770 points vs. We can observe CPU performance changes over time on each system when running CineBench R15 Multi-Thread in a loop as shown in the chart below. Our latest example is between the 15-inch Surface Laptop 3 15 and 12.3-inch Surface Pro 7 tablet each equipped with an Intel 10th gen Core i7-1065G7 CPU. It's easy to forget that larger laptops are generally faster than thinner laptops despite having similar internal specifications. As we've mentioned before in the past, the performance of a processor can vary greatly between two different laptops even if both are equipped with the same CPU. ![]()
