Jens Geyer commented on THRIFT-5192:
------------------------------------

I have observed similar things with (IIRC) netstd, found it strange as well. 
Didn't spend much time on it though.

> Is the buffered transport much slower?

>             Project: Thrift
>          Issue Type: Improvement
>          Components: C++ - Library
>    Affects Versions: 0.13.0
>            Reporter: Mario Emmenlauer
>            Priority: Minor
>              Labels: benchmark, perfomance

> I've used the current HEAD version of thrift for a benchmark of various 
> transports, protocols, servers etc. My focus right now is on throughput on 
> the local machine, so getting as many bytes as possible from one process to 
> another in a short amount of time.
> Generally, the good news, first, Thrift can be very fast and on a range of 
> modern desktop computers I get a top throughput between processes in the 
> range of 4-6Gb/sec.
> But there is one aspect that is striking: There is one transport that 
> performs worse than what I would have expected, and this is the "buffered" 
> transport. As an example, I can achieve around 5Gb/sec with a plain domain 
> socket transport, and still an impressive 3.6Gb/sec by wrapping a "framed" 
> transport. Wrapping with a "header" transport still gives 3.3Gb/sec, and the 
> fastest "http" transport achieves 2.6Gb/sec.
> Then comes a huge gap, before the fastest contestant with "buffered" 
> transport shows up with 1.3Gb/sec.
> Does anybody have any hints as to why "buffered" may be so much slower? What 
> is the difference between the buffering in "framed" that makes it almost 3 
> times faster?
