[jira] Resolved: (HTTPCORE-214) Investigate implementation of expand() method in CharArrayBuffer

["Oleg Kalnichevski (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HTTPCORE-214?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Oleg Kalnichevski resolved HTTPCORE-214.
----------------------------------------

       Resolution: Won't Fix
    Fix Version/s:     (was: 4.1-beta1)

I am not seeing any measurable impact on performance by this change. Besides, StringBuilder also simply doubles the internal buffer on expansion.

Closing as WONTFIX

> The CharArrayBuffer expand() method will sometimes double the size of the buffer array.
> However looking at the source code for ArrayList in the Java utils package reveals that they do:
>    int newCapacity = (oldCapacity * 3)/2 + 1;
> Would this be more efficient in CharArrayBuffer (in practice)?
> The standard benchmarks should be run to ascertain if this is the case.
