Load Profile Sierra and Millennium: Load Profile Training
Browser without any hint of slowdown or memory leaks.However, at the end-of-day demo, as we piped traffic data into EtherCalc and started to type formulas into the in-browser spreadsheet, the server suddenly locked up, freezing all active connections. We restarted the Node.js process, only to find it consuming 100% CPU, locking up again soon after.Flabbergasted, we rolled back to a smaller data set, which did work correctly and allowed us to finish the demo. But I wondered: What caused the lock-up in the first place?Profiling Node.jsTo find out where those CPU cycles went to, we need a profiler.Profiling the initial Perl prototype had been very straightforward, thanks largely to the illustrious NYTProf profiler, which provides per-function, per-line, per-opcode and per-block timing information, with detailed call-graph visualization and HTML reports. In addition to NYTProf, we also traced long-running processes with Perl's built-in DTrace support, obtaining real-time statistics on function entry and exit.In contrast, Node.js's profiling tools leave much to be desired. As of this writing, DTrace support is still limited to illumos-based systems in 32-bit mode, so we mostly relied on the Node Webkit Agent, which provides an accessible profiling interface, albeit with only function-level statistics.A typical profiling session looks like this:# "lsc" is the LiveScript compiler# Load WebKit agent, then run app.js:lsc -r webkit-devtools-agent -er ./app.js# In another terminal tab, launch the profiler:killall -USR2 node# Open this URL in a WebKit browser to start profiling:open recreate the heavy background load, we performed high-concurrency REST API calls with ab. For simulating browser-side operations, such as moving cursors and updating formulas, we used Zombie.js, a headless browser, also built with jsdom and Node.js.Ironically, the bottleneck turns out to be in jsdom itself:From the report above, we can see that RenderSheet dominates the CPU use: Each time the server receives a command, itProfiles loaded via profile manager slow to load pages

The value of your data depends on how well you organize and analyze it. As data gets more extensive and data sources more diverse, it becomes essential to review it for content and quality. However, only about 3% of data meets quality standards, which means companies with poorly managed data lose millions of dollars in wasted time, money, and untapped potential. That is where Data Profiling comes in — a powerful weapon to fight against bad data. It is the act of monitoring and cleansing data to improve data quality and gain a competitive advantage in the marketplace. In this article, we explore the process of data profiling, its definition, tools, and technologies, and look at ways how it can help businesses fix data problems.What Is Data Profiling (DF)?It is the process of examining source data and understanding structure, content, and interrelationships between data. The method uses a set of business rules and analytical algorithms to analyze data minutely for discrepancies. Data Analysts then use that information to interpret how those factors can align with business growth and objectives. Data profiling is increasingly vital for businesses as it helps determine data accuracy and validity, risks, and overall trends. It can eliminate costly errors that usually occur in customer databases, like missing values, redundant values, values that do not follow expected patterns, etc. Companies can use the valuable insight gained from data profiling to make critical business decisions. Most commonly, it is used in combination with an ETL (Extract, Transform, and Load) process for data cleansing or data scrubbing and moving quality data from one system to another. An example can help you understand what is DF in ETL. Often ETL tools are used to move data to a data warehouse. Data profiling can come in handy to identify which data quality issues need to be fixed in the source and which issues can be fixed during the ETL process. Data analysts follow these steps:Collection of descriptive statistics including min, max, count, sumCollection of data types, length, and repeatedly occurring patternsTagging data with keywords, descriptions, typesCarrying out data quality assessment and risks of joining dataDiscovering metadata and estimating accuracyIdentifying distributions, key candidates, functional and embedded-value dependencies, and performing inter table analysisBuild your career in Data Analytics with our Data Analyst Master's Program!

Edge 109, the Allocation sampling profiling type in the Memory tool now has two new options:Include objects discarded by major GC.Include objects discarded by minor GC.Without selecting these options, the Memory tool will continue to work as it did before, reporting allocations that are still alive at the end of the profiling session. In this mode, objects that are generated and garbage-collected (GC'd) and then disappear aren't tracked by allocation sampling.Select both options if you want to track garbage that is being generated by your website or app. In the resulting profile, you'll be able to see garbage that was generated by your JavaScript functions that was then GC'd. Use these options if you want to reduce the amount of garbage that your code is generating. To learn more about the differences between major and minor GC, see Trash talk: the Orinoco garbage collector.See also:Investigate memory allocation, with reduced garbage ("Include objects" checkboxes) in Speed up JavaScript runtime ("Allocation sampling" profiling type).Add the new Heap Snapshot Visualizer extension to Microsoft Edge to get new visualizations of the data that's in your heap snapshot files. Installing this extension adds a new Heap Snapshot Visualizer tool in DevTools. In the Heap Snapshot Visualizer tool, you can load a heap snapshot file to see it represented either as a directed graph or as a tree. These new visualizations enable you to explore the retainers chain from the garbage-collection (GC) root to an individual node.Graph view:Tree view:See also:Heap Snapshot Visualizer at Microsoft Edge Add-ons.ImprovementsHelp:How the profile for nTune loade
