FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package streetfight
StreetFight
StreetFight is a benchmarking tool aiming to quickly know what code have better performance against another one. It is not intended to be an exhaustive profiling library and probably won't grow any further.
Note that StreetFight is following the Elegant Objects principle, and uses some functional programming internally with the help of Funktions.
Install
StreetFight requires PHP 7.2.
Example
Here's the common way to execute a benchmark and retrieve a report directly from it. This example compares the performance of pre-increment and post-increment instructions.
Match objects
There are 3 types of matches:
StreetFight\Match\Match(int $rounds, RoundInterface $round): it will take a number of rounds to run, and aStreetFight\Round\RoundobjectStreetFight\Match\TimedMatch(int $time, RoundInterface $round): it will take a minimum time in milliseconds while the benchmark will run, and aStreetFight\Round\RoundobjectStreetFight\Match\AutoTimedMatch(RoundInterface $round): contrary toTimedMatch, it will automatically compute the maximum time for the benchmark to run, and only accepts aStreetFight\Round\Roundobject as parameter
Report objects
There are several types of Report objects:
StreetFight\Report\Report(MatchInterface $match): the mainReportobject, can only take aMatchobject as parameter; the results are returned as raw secondsStreetFight\Report\RoundedSecondsReport: a decorator for the mainReportobject; the results are returned as seconds rounded to 2 decimal digitsStreetFight\Report\MillisecondsReport: a decorator for the mainReportobject; the results are returned as millisecondsStreetFight\Report\MicrosecondsReport: a decorator for the mainReportobject; the results are returned as microsecondsStreetFight\Report\PercentageReport: a decorator for the mainReportobject; the results are returned in percentageStreetFight\Report\AscSortedReport: a decorator that sorts a report in ascending directionStreetFight\Report\DescSortedReport: a decorator that sorts a report in descending direction
Set BEFORE and AFTER hooks
If you need to run some specific routines, you can set them in the Round object:
Passing some data to tasks
As you can see from the above example, the same data is used across all tasks. Furthermore, we could need to generate random data at each iteration. But since mutability makes it really difficult for StreetFight to keep track on the data (and passing it into objects complicates the API), it has been decided to define it outside of StreetFight itself in a procedural way. So, here's how you would use arbitrary data, based on the previous example:
Side note
Depending on what code you're benchmarking, the execution time can exceed the max_execution_time directive of PHP. Just set set_time_limit(0) and you'll be all good.
