Benchmarking: Benchmarking is the process of testing the performance of your application under a specific workload or set of conditions. You can use tools like Apache Bench or Siege to simulate load on your application and measure how it performs. - Source: dev.to / over 2 years ago
While the server creation is still somewhat more imperative in nature, client connections are now handled via an object which inherits off socketserver.BaseRequestHandler. This requires the implementing class to define a handle() method, which for TCP will expose self.request to hold a socket referencing the connection. Now to show multiple connections working I'll utilize the Apache HTTP server benchmarking tool.... - Source: dev.to / almost 3 years ago
Using the example above, Iโll send some traffic to the endpoint using Apache Benchmark. - Source: dev.to / about 3 years ago
Apache Bench aka "ab" ab -n 1000 -c 100 http://localhost:3000/ 1000 requests with a concurrency of 100 https://httpd.apache.org/docs/2.4/programs/ab.html. - Source: Hacker News / over 3 years ago

Java has the VisualVM. https://visualvm.github.io/ I would love a similar tool for Racket. - Source: Hacker News / 8 months ago
For the purposes of this demo, letโs simply count the number of retrieved rows. The Thread.sleep() is included to give me time to open VisualVM and check the metrics:. - Source: dev.to / almost 5 years ago
To track query-level metrics, check out the Hibernate Statistics section. Profiling tools like YourKit or VisualVM can help you analyze key metrics such as:. - Source: dev.to / over 1 year ago
If you're curious, attach VisualVM and watch the RAM usage graph. You'll notice that Java performs garbage collections long before reaching allocating the maximum amount of RAM allocated, and you can't even feel any performance issue in-game. Source: about 3 years ago
Hangs and deadlocks are significantly harder to debug. A first step is taking a thread dump so you can see what each thread in the JVM is currently trying to do. I like VisualVM for this, you can also use the command-line tools jps -l (to list all Java PIDs) and jstack for taking a thread dump. Source: about 3 years ago
