Andrew Gaul commented on THRIFT-1815:
-------------------------------------
Sorry I did not realize that Thrift moved to git. I forked the mirror on
GitHub and submitted a pull request:
https://github.com/apache/thrift/pull/30
However, the original patch applied without conflicts and compiled without
warnings. I show the last git commit as 8a3c01a and svn revision as r1410139.
Can you give me any more information?

> Key: THRIFT-1815
> URL: https://issues.apache.org/jira/browse/THRIFT-1815
> Project: Thrift
> Issue Type: Improvement
> Components: Compiler (General)
> Affects Versions: 0.9
> Reporter: Andrew Gaul
> Labels: performance
>
> This results in slow performance on FUSE- and network-based filesystems,
> e.g., eCryptfs. std::ostream << std::endl emits a newline and flushes
> buffers to the kernel[1], yielding excessive system calls. Instead, emit
> "\n" which does the equivalent without the flush[2]. The attached patch
> accomplishes this while minimizing code churn by removing "using namespace
> std" and introducing a static variable endl.
