How to use Caliper benchmark beta snapshot without maven?

由 谁说我不能喝 提交于 2020-01-15 06:17:30
问题 I have been asked to use Google's Caliper project to create a few microbenchmarks. I would very much like to use the annotation features of the newest beta snapshot, but aside from a few small examples I am having trouble finding good documentation on how to actually run the thing... There is a video tutorial up which instructs users on the new maven integration feature, which I was also asked NOT to use. Right now I just have a small example stripped from one of theirs, modified with some

How to use Caliper for benchmarking?

由 て烟熏妆下的殇ゞ 提交于 2020-01-14 08:02:08
问题 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 I get lost quickly. I have downloaded the Caliper jar file but I'm not sure what folder it should be in. I've also downloaded Maven for Eclipse plugin but I'm not even sure if that is necessary. Is it possible to install Caliper from the 'Install New Software..' option in the Help menu in Eclipse?

Strange performance drop of JDK8 LocalDate.toEpochDay

由 自闭症网瘾萝莉.ら 提交于 2019-12-30 21:11:54
问题 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 curious if I could do better. I eliminated some branching and all but one division, however the speedup is worse than expected. So my first question how is it possible that an algorithm using multiple division takes only about 30 cycles (throughput). Holger's comments seem to have answered this:

How to measure file read speed without caching?

由 ￣綄美尐妖づ 提交于 2019-12-17 22:53:30
问题 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 non-sense, so I benchmark. However, during the benchmark the whole file content gets cached in RAM, unlike in the real run. Thus the run-times of the benchmark are much smaller and most probably unrelated to the reality. I'd need to somehow tell the OS (Linux) not to cache the file content, or better

Caliper test using exec-maven-plugin is saying main method signature isn't valid

问题 I'm trying to get Caliper working with maven, I haven't successfully ran a caliper benchmark test as of yet. Caliper version: 1.0-beta-1 My benchmark: public class MyXercesSAXHandlerBenchmark extends Benchmark{ @Param({"10", "100", "1000", "10000"}) private int length; public void timeNanoTime(int reps) { for (int i = 0; i < reps; i++) { System.nanoTime(); } } public static void main(String[] args) { CaliperMain.main(MyXercesSAXHandlerBenchmark.class, args); } } My maven pom.xml has:

How to specify the command line when using Caliper?

由 旧巷老猫 提交于 2019-12-12 12:34:45
问题 I find Google's micro benchmark project Caliper very interesting but the documentation is still (except some examples) quite non-existent. I have two different cases where I need to influence the command line of the JVMs Caliper starts: I need to set some fixed (ideally alternated between a few fixed values) -D parameters I need to specify some fixed (ideally alternated between a few fixed values) JVM parameters I saw some discussion about adding features like this but I could not conclude if
