![]() Next, examine whether reads or writes seem responsible. Tip: A good way to start using statistics is by first looking at the metadevice's Load value. State database replicas, hot spare pools, and individual slices cannot show statistics. When you drag a slice to the Statistics Graphs window, you effectively drag the entire disk. This includes the Metadevice Editor canvas, the Objects list, the Slice Browser window, and the Disk View window. You can drag and drop objects from any of DiskSuite Tool's windows to the Statistics Graphs window. (Refer to the kstat(3K) and iostat(1M) man pages for more information.)īecause DiskSuite Tool uses the kstat interface, it can only present disk-level statistics, not slice-level. Preliminary Information for Performance Monitoring and GraphingĭiskSuite Tool displays a subset of the raw statistical data provided by the kstat(3K) interface. By moving that column to another disk, you are able to better balance the I/O for the entire metadevice. For example, while monitoring a RAID5 metadevice, you might notice one column (slice) that shows much more I/O than the other columns. This enables you to monitor general performance trends, look for abrupt changes, and compare data collected for different parts of a configuration. The performance monitoring capability within DiskSuite Tool is best suited for the day-to-day operation of DiskSuite in spotting performance problems associated with hot-spots and bottlenecks. This requires a different methodology and set of tools to cover such tasks as device configuration, file system management, data collection, test load generation, and the like. Performance analysis assumes that you can set up multiple configurations and collect a different set of data from each configuration. ![]() Performance analysis, on the other hand, aims to maximize system throughput or minimize latency by trying out various configurations until the "best performance" is achieved. Performance monitoring assumes that you are using a given configuration that you cannot easily or often reconfigure. The goal of performance monitoring is to maximize system performance by making small changes while maintaining data availability. Performance AnalysisĭiskSuite Tool gives you the capability for simple performance monitoring of metadevices and physical disks. You can also open Task Manager and click on Performance and then click on Memory.Performance Monitoring vs. This is fine, but you need to make sure the machine has a decent amount of RAM, meaning nothing less than 4 GB. Since Windows 10 can run on older devices, I’ve seen a lot of people install it on old desktops and laptops. Method 3 – Upgrade Memory (RAM)Īnother thing you want to check is to see how much RAM you have installed on your machine. So try uninstalling Skype and see if that works. In online forums, I’ve heard a lot of people complain that Skype was the cause of the disk usage spike. For starters, always start by disabling any third-party anti-virus/anti-malware program as those programs can have a tendency to access the disk all the time. If you find that everything loads fine on a clean boot, then slowly enable each startup program one by one until you determine which program is causing the slowdown. Just set aside a few hours on a weekend to get it done. It’s a bit time-consuming, but totally worth the effort. I recommend trying it because is usually fixes a lot of other issues too. Microsoft has a great article on how to perform a clean boot. SSDs are fast and unless you have some program that is accessing the disk all the time, it really should never be at 100% for more than a few seconds. If you have an SSD installed on your machine and are having the disk usage problem, it’s most likely a problem with the firmware. Disabling Windows Defender – Except for Method 6, don’t disable Defender.Modifying Page File – You should leave it so that Windows manages the page file.Disabling Windows Search or Superfetch – Again these are core Windows services and you should not disable them.Disabling the BITS service – It’s required by Windows for your PC to be updated and it won’t help disabling it.Try to avoid doing anything listed below: On the web, I came across a whole bunch of solutions that just didn’t settle well with me because they can cause more problems later on. Before we get into those, here’s what you shouldn’t do. In some cases, the solution is easy and in others, it’s a bit trickier. Now let’s talk about how we can determine what is causing the issue and then come up with a solution.
