...nks capacity can be this padding. It is not difficult using tc as it stands to generate a rate table does a fairly good job of estimating the bandwidth used on your ADSL link by large packets, or by small packets of a consistent size. You can''t do both. You can play with the figures (overhead and base rate) and get all sorts of trade offs. If you are prepared to overestimate the links carrying capacity at some packet sizes, (a serious error for VOIP), then you can get the worst case error down to around 20%. If you don''t want at overestimate link capacity under any circums...

According to the AppDB EU2 1.09 has a platinum rating, but it's constantly crashing on me. I installed the game from the CD, updated to the latest version (1.09), and the game launches just fine. When it gets into the menu I notice that it's running a lot slower than it should be. I can start a single player game and it still runs slow, and then crashes. It doesn't matter what I do in

...urther pursuing my curiosity to measure the efficiency of R/C++ interface, I conducted a simple matrix-vector multiplication test using .C and .Call functions in R. In each case, I measured the execution time in R, as well as inside the C++ function. Subtracting the two, I came up with a measure of overhead associated with each call. I assume that this overhead would be non-existent of the entire code was implemented in C++. [Please let me know if my approach is somehow faulty.] The results of this simple test have significant implications for my software development approach. I hope others find this...

Does anyone have any recommendations for overhead paging systems for use with Asterisk? Thanks, Randy Johnson -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20031113/82ae09ec/attachment.htm

Hi I''m using wondershaper like script. But noticed imperfect scheduling. By googling, I found some patches that takes the aal5 atm overhead in the scheduling algorithms. http://www.adsl-optimizer.dk/ADSL-optimizer/ Before trying it, has anyone tried these patches? they apply on 2.4.29 kernel and 2.6.9 TC. I use centos4 with a 2.6 kernel, so I can''t try these easily. Thanks

I've rummaged through the archives and documentation and have yet to find references to nbsd or mention of how to implement overhead paging using chan_oss as mentioned in the list previously. I suspect that one would use a soundcard in the PBX system and feed the output to speakers and/or PA system. Would someone please point me to some procedures or documentation to acomplish overhead paging? Best regards, Erik -----Forwarded...

Hi all, I have updated my GSoS proposal: "FastPolly: Reducing LLVM-Polly Compiling overhead" (https://gist.github.com/tanstar/5441808). I think the pass ordering problem you discussed early can be also investigated in this project! Is there any comment or advice about my proposal? I appreciate all your help and advice. Thanks, Star Tan Proposal: https://gist.github.com/tanstar/54...

Hi. I wrote in a reply to a mail on here recently that you can''t set mpu (minimum packet unit) on HTB as you can on CBQ. I''ve just noticed that there is a patch on devik''s site which does mpu and overhead. http://luxik.cdi.cz/~devik/qos/htb/ For dsl users mpu is, for practical purposes going to be 106 - overhead is still variable though, depending on packet size. Having these should let you push upstream bandwidth rates a bit closer to the limit. Andy. ________________________________________...

Hello list, I need to realize a complicated custom shaping setup, and given very little experience with shaping I just can''t wrap my head around it. I am not seeking a complete script, I just need an idea/a set of pointers on how to best subdivide traffic accordingly to my needs, and which shapers to place on every leaf. I am very experienced with netfilter and have minor experience with

...mentation but reading ogg specs i didn't understand this lines: "We simply add the lacing values for the total size; the last lacing value for a packet is always the value that is less than 255. Note that this encoding both avoids imposing a maximum packet size as well as imposing minimum overhead on small packets (as opposed to, eg, simply using two bytes at the head of every packet and having a max packet size of 32k. Small packets (<255, the typical case) are penalized with twice the segmentation overhead). Using the lacing values as suggested, small packets see the minimum possible by...

Jon, I need to create a database of basics blocks and their execution time. The only thing I'm concerned is if a block A is more expensive than a block B. Do you think that even with the overhead I would be able to get the A > B information? Like: overhead + time(A) > overhead + time(B) => A > B. If so, I'm not too much concerned about the accuracy. Not sure if I was clear, Thanks again Vanderson M. Rosario 2014-09-17 17:26 GMT-03:00 Jonathan Roelofs <jonathan at code...

Hello, after spending several hours reading archives, I decided to write new post. I successfully set up packet classification, made some basic HTB setup, made some simple graphical representation from HTB statistics data... BUT, I cannot figure out how to refine HTB to get this behaviour: I need that class "p2p" should be the last one to get some link capacity. If I set both RATE
