Apache ab might be a bit more popular than VisualVM. We know about 23 links to it since March 2021 and only 21 links to VisualVM. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
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 / 2 months 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 / 9 months ago
Using the example above, I’ll send some traffic to the endpoint using Apache Benchmark. - Source: dev.to / 10 months 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 / about 1 year ago
Apache Testbench is an option. It's a cli tool that simulate some level of traffic. Source: about 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: 11 months 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: 11 months ago
The Java VisualVM project is an advanced dashboard for Memory and CPU monitoring. It features advanced resource visualization, as well as process and thread utilization. - Source: dev.to / 12 months ago
This sounds like a server thread freeze/deadlock/crash or something. I think I would start debugging this using a tool like VisualVM; attach it to the game, wait for the hang, take a thread dump, and check what the server thread is up to. Source: about 1 year ago
Just wanted to chip in to say that /u/UtilFunction is correct. The proper way to measure memory consumption of any Java application independent of which garbage collector is used is to perform a heap dump (which automatically forces a complete garbage collection). I like to use VisualVM for that. Source: about 1 year ago
