Dear rsync folks, I'd like to request/suggest that cli options to set TCP send/receive buffers be added to rsync client-side. Summary: I'm aware that a daemon's config-file can set socket options for the server side (e.g. SO_SNDBUF, SO_RCVBUF). That is useful. But when trying to get high-throughput rsync over long paths (i.e. large bandwidth*delay product), since

Hello list, right now SSH Tunnel / scp is reaches just around 76Mb/s on my E5 Xeon using AES-NI but openssl reaches around 600-700Mb/s using 128aes-cbc cipher. As far as i understand http://www.psc.edu/index.php/hpn-ssh this is due to very small buffers in ssh / scp. Is there any work on this? Like autotuning the buffer size? Are there plans to integrate the hpn patches? Greets, Stefan

Dear Mihail, I've added these two publications to the publications page. Please review it and let me know if I need to make any changes. In particular, if you have URLs to use for the papers, having those would be greatly appreciated.

Hello, I would like to submit two papers that use LLVM to the Related Publications section. Both papers focus on code isolation applied to perform piecewise compiler optimizations. The code isolation process is performed by CERE, an open source tool based on LLVM. The second paper is an extended version of the first one. 1) Piecewise Holistic Autotuning of Compiler and Runtime Parameters

Correct me if wrong, but I was under the impression that the processing required for playback was totally independent on the level of compression. The encoder looks for polynomials that fit, and it takes much more processing to find polynomials with a very good fit and small residuals. On the other hand, the decoder just has to multiply out the stored prediction, which is independent of the

My friend somehow managed to get a BDP-95, even though the hardware isn't scheduled to ship until March. The problem is that the manual makes no mention of FLAC, at all, and only the web page claims to support the format. Playback of flac seems to work, but files from one online vendor work flawlessly while files from other online vendors have strange glitches that sound like a

I have a customer who is complaining about slow SFTP transfers over a long haul connection. The current transfer rate is limited by the TCP window size and the RTT. I looked at HPN-SSH, but that won't work because we don't control what software the peer is using. I was thinking about coding a much more modest enhancement that just does SO_RCVBUF for specific subsystems. In the interest

Greetings, I've been doing a little testing with the stdio forwarding support added in recent snapshots and have encountered one possible issue. First, I should say that this feature generally seems to work. However, I haven't been able to get it to work when connecting to a server running SSH.COM's product. The config file I am using is fairly simple: Host sfe1 LogLevel debug3
