URL: https://github.com/apache/commons-lang/pull/812#issuecomment-974500459


   > Thank you @kinow ! It will be simpler to compare our results with hardware 
and OS hopefully the only difference.
   
   I have a Windows 10 here too, but rarely use it. I will try to run the tests 
on Ubuntu LTS and on Win 10. JVM 8 and 11 only would be enough?

> Please look at the sources in JDK, where 
> java.lang.AbstractStringBuilder#append(boolean b)
> In short, for basic types, should not convert them to String, but use 
> StringBuilder directly, will bring far better performance.
> BUT I just foundout that you did not bring this issue, this issue is already 
> in commons-lang before your pr.
> So I will not stop you from merging this in, but still I will find time to 
> refactor the whole join serial functions later.
