Subject [jira] [Commented] (IGNITE-3639) IGFS: Local secondary: investigate whether we need BufferedOutputStream for create/append.
Date Fri, 12 Aug 2016 12:35:20 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-3639?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15418761#comment-15418761
] 

Taras Ledkov commented on IGNITE-3639:
--------------------------------------

1. IgfsOutputStreamImpl has already been buffered. A buffer is implemented at the class IgfsOutputStreamAdapter.
2. Simple benchmark on the my localhost doesn't show significant difference between LocalFs
with and without buffer (the result dispersion is greater then the difference). We have to
measure it at the benchmark labs to ensure.

> We already have a buffer inside {{IgfsOutputStreamImpl}}. Do we really need to wrap {{FileOutputStream}}
into another buffer?
