[jira] [Commented] (TEZ-4161) Speed up TestTezUtils

    [ https://issues.apache.org/jira/browse/TEZ-4161?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17095943#comment-17095943 ] 

Jonathan Turner Eagles commented on TEZ-4161:
---------------------------------------------

Before: 2.561s
After: 1.011s

Couple of problems here. Adding one character is just slower than adding many at a time. Additionally, the initial buffer size for the string buffer was improperly sized and had to be resized upon the last addition.
