similar to: Vista SP1 performance fix - maybe!

hi all, I have a vista client (Vista Business) doing a subversion checkout to a samba share (mapped to drive letter) but it's taking a VERY long time. when i checkout to my local hd it takes about 30 seconds, how can i start troubleshooting this? The subversion checkout is about 20 MB (on disk) and everything is connected via standard 100 mbit ethernet network. (vista client is connected via

If this is the wrong place to post this, please forgive me, and PLEASE point me to the correct place. I am looking to hire someone to write a function to scan a ogg-vorbis stream running on Debian etch and checking for two things. The first is static, the second is "dead-air". The function require no GUI, just read a configuration file for the url to scan and how many seconds of

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

Hello everybody. Last monday I sent an email to the LLVM dev mailing list saying that I was looking forward to working on these GSoC projects: *Advanced Heuristics for Ordering Compiler Optimization Passes* and *Machine learning and compiler optimizations: using inter-procedural analysis to select optimization* I currently do an undergraduate research on compiler autotuning of Rust code, more

Awesome, thanks! As per your suggestion, I read the description of these two projects: Advanced Heuristics for Ordering Compiler Optimization Passes Machine learning and compiler optimizations: using inter-procedural analysis to select optimizations and they are amazing! Indeed, they are very close to my interest in autotuning. I didn't see them on the list before. If I choose to focus on

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

Hello again! Previously, I introduced myself as a prospective GSoC student interested in LLVM. Per Mr. Doerfert suggestion I took a look at two other projects that he said could interest me due to my ongoing research in autotuning. The projects are: Advanced Heuristics for Ordering Compiler Optimization Passes Machine learning and compiler optimizations: using inter-procedural analysis to select

I'm experiencing extremely slow performance when trying to copy files from and to a samba 4 share. I'm using Debian and the Samba 4 SerNet packages and everything is up to date on the client as well as on the server. The connection is made through 100Mbp/s ethernet, but the problem also exists on a local virtual machine that runs on the Debian server. By extremely I mean really abysmal:

[NB: General information regarding HPN-SSH can be found at http://www.psc.edu/networking/projects/hpn-ssh ] This is a beta release of HPN12 but I'd like to get some user experiences with it if anyone is so inclined. This version of the HPN patch more closely conforms to the openssh nomenclature and coding style, it eliminates the use of command line switches in favor of -o options, it

Hello! My name is Emanuel and I am an undergraduate student from Brazil (at the University of São Paulo) wanting to participate in this years GSoC on LLVM. Specifically, on the "Improve parallelism-aware analyses and optimizations" project. I currently do research on autotuning of LLVM IR optimization passes and I am sitting for a class about parallel computing, but I have been studying
