Unusual events suggesting the database and host IO is slow. Figure 7-45 AHF Insights From here we can go back out to the home screen to explore the Operating System metrics. In this example we can see Autonomous Health Framework has detected the Oracle Processes were blocked in D State, which means they were stuck waiting for IO to return. We can also see some disks had a long wait time. Figure 7-46 AHF Insights Expanding this gives us graphs showing disks with average wait time greater than 20 milliseconds and top IO consuming processes. Figure 7-47 AHF Insights And scrolling further down we can see problematic snapshots. This one shows us which disks were slow. Figure 7-48 AHF Insights High CPU Usage Example Scenario Here’s a different scenario looking at anomalies detected by Autonomous Health Framework, in this case we see the latency for Database global cache messages higher than expected. Autonomous Health Framework tells us the cause and recommended action. So now we know CPU is a bottleneck. Figure 7-49 AHF Insights Going to the OS issues report page in this scenario shows us a finding for high CPU usage. Expanding that finding shows us details about when the CPU usage was high. As we scroll down we see CPU usage graphed over time. Figure 7-50 AHF Insights Continuing down shows us the CPU usage for different processes. Here we can see the database background and foreground processes are consuming an average of over 80% CPU and a Max of over 100% CPU. Figure 7-51 AHF Insights Use PerfHub report within Insights to identify and tune poor performing database workloadsAHF embeds the most useful performance tuning reports, directly within the AHF Insights report. The Performance Reports section contains: PerfHub Reports AWR Reports AWR Compare Reports Figure 7-52 AHF Insights - Home Figure 7-53 AHF Insights - Performance Reports Open the PerfHub report. The Database Performance Hub report gives details about the database workload. Figure 7-54 Performance Hub The first thing to understand is what your active sessions are doing – an active session is one actively working on behalf of the client. By default the Performance Hub Report opens on the ASH Analytics tab. ASH stands for Active Session History, which is a database feature that samples active database sessions. Expand the graph to get a better look. Here we can see our highest wait class is CPU,. IO Graphs. The first way to show IO information is the Wireshark IO Graph, in Statistics IO Graph.

Existing documentation and whitepapers for WPA tends to focus on multimedia and game development, but if you are and adventurous spirit and want to learn about how your favorite database works, using WPA to analyse SQL Server works can reveal a great deal of information and help you spot performance improvements that can be leveraged in your application. One of my favorite use cases for WPA is to collect IO activity (this will collect every single IO request) and then visualize the Disk Offset as a graph. This is an incredibly simple, yet powerful, way to visualize random IO vs. sequential IO patterns. If you have a feeling WPA and XPerf/ETW are somehow related to SQL Server Extended Events, that is because they are, very much so. Finally, some readings to get you started on using WPA:Quick Start Guide: WPA BasicsPerformance Analysis WhitepapersThe Lost Xperf Documentation–Disk UsageWPA–Xperf Trace Analysis ReimaginedWindows I/O TracingThe USE methodUSE stands for Utilization, Saturation and Errors, and the USE Method is a formalized approach to investigating performance troubleshooting. Its focus is on identifying resources in a system and then for each one measure the utilization (percent in use compared to maximum bandwith), the saturation of the resource (extra work queued because the resource cannot service due to 100% utilization) and errors.When used in SQL Server context, the tricky part is to identify the resources and how to measure the utilization/saturation/errors. Some resources are obvious: disk, CPU, memory, network. Sometimes even simply starting with the USE method and measuring these hardware parameters is a good way to start a performance investigation, at the very least you'll know what hardware component is saturated, if any.

Runtime for asynccode, non-blocking IO over both TCP and Unix domain sockets, and a foundationfor WebAssembly multitasking.The protocols for both IPC and client-server communication are based on theRemoc crate, which implements transport-agnosticchannels, binary blob transport, remote procedure calls (RPC), watchable datacollections, and other networking constructs. This will save a lot ofdevelopment time that would otherwise be spent writing networking primitives.Using Remoc makes it difficult to standardize a top-to-bottom protocoldefinition, and the assumption is being made that no programs other than Hearthor its forks will be using the protocol. The development time saved is morethan worth the loss of interoperability.RenderingScenes are rendered with rend3, abatteries-included rendering engine based onwgpu. rend3 includes PBR, lighting, a rendergraph, skybox rendering, frustum culling, rigged mesh skinning, tone mapping,and other handy renderer features that Hearth doesn't need to do itself.Additionally, rend3's frame graph allows us to easily extend the renderer withnew features as needed.Terminal EmulatorThe terminal emulator is implemented with the help of thealacritty_terminal crate, whichparses the output of native child processes and writes it into a display-readygrid of characters. Then, Hearth draws the characters onto 2D planes projectedin 3D space using MSDF textures generated with themsdfgen crate. This rendering is a customnode in the rend3 frame graph with a custom shader.TBD: can we load glyph outlines from a TTF file without building Freetype?note: the ttf-parser crate looks like what we need)TBD: UX for interacting with in-space terminals?InputWebAssemblyTUIsCLIsDevelopmentHearth is more of a research project than a general user- or production-readyapplication, and its users are intended to.

2025-04-03CCSIO Benchmark is an intelligent drive speed checker from Swiss-based storage expert Pipemetrics. The tiny portable program (210KB download) uses multiple combinations of options to automatically find the fastest possible read and write speeds for any storage device.This means you’re not asked to make any of the usual testing options. You don’t have to try and decide which buffer size or count is best, which IO mode to use, because CCSIO always runs through every possible combination of settings.The supported buffer sizes: 8K, 16K, 32K, 64K, 128K, 256K, 512K, 1M, 2M, 4M, 8M, 16M.Buffer counts are 1, 2, 4, 8, 16.CCSIO Benchmark runs its tests using unbuffered, unbuffered sequential and (for reads only) buffered sequential IO modes.This makes for plenty of tests -- 180 reads, 120 writes -- but we found the process took a little under five minutes on fast SSDs, a little over on slower devices. The program keeps you up-to-date with the latest figures as it works, and there’s a Cancel button if you get bored.The finished results are displayed as simple Read and Write graphs, each with the maximum MBps value.If you need more details there are options to view or save the raw data in a text report.There is even an option to upload an image of the app window -- the basic drive details and results graph -- to the CCSIO server, where it’ll be assigned a unique URL which you can share with others.CCSIO Benchmark (that’s "Cold-cache Sequential I/O", if you were wondering) is available for Windows Vista and later.
