I am trying to figure out how to use Caliper to do benchmark testing in Eclipse and I am getting nowhere. I tried following the 26 minute tutorial found here: https://code.google.com/p/caliper/ but...

Guava has a guava-tests subdirectory that contains a directory subtree called benchmark. It appears that executing mvn test (or mvn install) runs the full suite of unit tests in the test subtree, b...

I've recently started learning Go and I'm trying to implement a map that can be used concurrently by multiple groutines. I want to be able to compare my implementation to a simple sync.Mutex-protec...

i have a caliper benchmark (1.0-beta-2): import com.google.caliper.Benchmark; import com.google.caliper.runner.CaliperMain; public class MyBenchmark { @Benchmark public int a(int rep) { return...

I tried to optimize the RAM usage of a Android game by changing int primitives to shorts. Before I did this I was interested in the performance of the primitive types in Java. So I created this li...

I was curious if we finally get a fast datetime library with JDK8. Nearly all LocalDate computations use toEpochDay so I looked at the source and the large number of divisions and branches made me ...

I have a Java project in Eclipse, with JUnit tests in my src/test directory. I've also added a class to my tests with Caliper microbenchmarks, and I'd like to be able to run these tests from within...

Anyone in computer science will know that HeapSort is O(n log n) worst case in theory, while QuickSort is O(n^2) worst case. However, in practice, a well implemented QuickSort (with good heuristics...

I am trying to use Google Caliper to benchmark some simple code. I am using the examples from their websites. Here's what I've done so far: Downloaded the Caliper JAR and added it to my Netbeans ...

Guava's ImmutableSet seems to perform quite poorly in my benchmark concerning contains. For some sizes it gets even much slower than List: size benchmark ns linear runtime 100000 ListContains 110...

My java program spends most time by reading some files and I want to optimize it, e.g., by using concurrency, prefetching, memory mapped files, or whatever. Optimizing without benchmarking is a no...
