> Project: Thrift
> Issue Type: Improvement
> Components: Compiler (General)
> Affects Versions: 0.9
> Reporter: Andrew Gaul
> Labels: performance
> Fix For: 1.0

> 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.
