David Georg Reichelt commented on SUREFIRE-1454:
------------------------------------------------
Surefire3 means commit c10e717d44edd45772bdf696e2cdc2e942ee7643, X axis is
count of lines printed to stdout and y axis is average duration of execution (x
lines are printed 100 times to stdout, this is repeated in 3 VM starts, and
over all this executions the average is calculated).
> Speedup Standard Output if Tests

> Project: Maven Surefire
> Issue Type: Improvement
> Components: Maven Failsafe Plugin, Maven Surefire Plugin, process
> forking
> Reporter: Tibor Digana
> Assignee: Tibor Digana
> Priority: Major
> Fix For: 2.21.0

>
> Currently, surefire creates a new byte array with size of the input *3 for
> saving the unescaped input. This made surefire way slower than running a test
> directly in eclipse or with gradle, if it used standardout or error heavily.
> By using a list for saving the elements and converting them to an array
> afterwards, this problem is solved, and stdout-heavy surefire tests get
> faster.
