[jira] [Created] (MYFACES-3450) [perf] use grails StreamCharBuffer
instead FastWriter in HtmlResponseWriterImpl
[perf] use grails StreamCharBuffer instead FastWriter in HtmlResponseWriterImpl
-------------------------------------------------------------------------------
Key: MYFACES-3450
URL: https://issues.apache.org/jira/browse/MYFACES-3450
Project: MyFaces Core
Issue Type: Improvement
Components: JSR-314
Reporter: Leonardo Uribe
Assignee: Leonardo Uribe
Looking for a solution to replace the default FastWriter implementation, with one that allocate multiple blocks on demand, and in this way reduce the memory used to render a page, I founded one cool implementation in:
org.codehaus.groovy.grails.web.util.StreamCharBuffer
http://grails.org/doc/latest/api/org/codehaus/groovy/grails/web/util/StreamCharBuffer.html
This file has Apache v2.0 license, so we can include it into MyFaces and use it into our HtmlResponseWriterImpl as internal buffer. I did some performance tests and I notice the impact in speed is minimal or non existent, but in memory it is good enough, because HtmlResponseWriterImpl usually is cloned on ajax requests and FastWriter always initialize a buffer, no matter if it is used or not, and if the page is big, the buffer grows without unnecessary copy operations.
