Well, I don't know how to tune it more, it connects at about that rate in a mediocre rural landline. ILBC uses samples of 30ms, so if you set the trunkfreq set to 20 you will be using more of the necesary scarce bandwidth AND dropping sample info in each frame, thus making audio choppy and unclear. Make shure to disallow all codecs and then allow only ILBC or lpc10 (search for it in

Hello everyone, First of all, great job on the 4.8-R. We have been a long standing user of FreeBSD and are very happy with everything. Now my question. I am trying to stress test a new Dell PowerEdge server and find the limits of its hardware and my tuning. Here are the server stats: * 2x Xeon 2.8 with SMP compiled, hyperthreading NOT compiled in kernel * 4 GB of RAM, 8 GB of swap on Raid 1

Hi all - (Re my previous question to the list, I managed to generate an ROC plot for my SVM by ranking the data using the Decision.Values property. Thanks for your responses) I have now started tuning the SVM to get optimal parameters for the RBF kernel and I ran into a problem. Whatever parameter ranges I specify, I always get the same error values for all combinations of parameters it

Hello All: I've been requested to add some TCP tuning parameters to some CentOS 5.4 systems. These tunings are for the TCP receive buffer windows: net.core.rmem_max net.core.wmem_max Information on this tuning is broadly available: http://fasterdata.es.net/TCP-tuning/linux.html http://www.speedguide.net/read_articles.php?id=121 Potential downsides are available:

It seems to me the best course might be to let Linux handle the memory. It'll devote a big chunk of it to disk cache, which will probably do more for performance than anything you could tweak on Samba. I'm not too worried about Samba tuning myself, since our server bottlenecks at the 100baseT full-duplex ethernet connection it's on -- it can easily saturate the bandwidth. If we

Hi, I would like to accelerate CURD operation of LDAP. Please let me know a tuning setup of OS or Samba. Although I am performing shift verification to Samba 4.1.12 from OpenLDAP 2.3, the CURD operation using a LDAP interface becomes 1/10 or less speed compared with OpenLDAP. Although this OpenLDAP is performing an optimized tuning setup, Samba is in the default state immediately after carrying

Hello all. I was hoping you guys could help me with understanding the best methods of performance tuning rails rendering time. Basically, I have my site up and running and while doing some performance tuning I saw that each page load spends most time in Rendering ~80% vs DB time ~ 1%. I found a bunch of bugs in extra SQL calls but obviously all of this would affect the 1% time which is not

Hi all! I've seen a number of posts regarding Samba performance - either comments about perceived poor performance, or recommended parameter changes. Instead of some arbitrary buffer numbers, or "play with it until it works", are there any analysis tools that can give quantitative answers ? Something where instead of just saying, "Samba is too slow", I could say,

I mentioned this problem in a previous post (in November). This time I'm including a patch. Version: OpenSSH_2.3.0p1 Keywords: setsockopt keepalive hang masquerade interactive Symptom: For protocol 2, socket options (especially keepalive) are not being properly set for OpenSSH_2.3.0p1, even when request in the config files. Furthermore (for either protocol), keepalive is only set for

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 List, I googled on this, and despite getting some hits (due more to the terms performance and tuning I think than anything) I was unable to locate useful links for actual software. I'm seeking software that will run on CentOS (or really any linux install period) that will assist me in testing and tuning my vehicle. I'm involved in import

tuning for ulaw g.711 - Polycom IP500 I've got QoS ironed out at this point (dedicated section of bandwidth with VoIP having priority), yet ulaw is still unusable due to small 'holes' in the audio. Running iperf tests shows packet loss at very low percentages (< 0.02 %), and when we do drop, it's only 1 packet at a time. I thought ulaw was supposed to handle this OK.

Hi, I am having difficulties in finding ways to analyse scatter plots and quantitatively differentiate between them. Since this is best demonstrated by a figure, I have attached one with 4 subfigures (a)-(d). Qualitatively (and I hope you would agree with me), sub-figures (a), (b), and (d) seem to represent uniform 2d scatters. It is hard for me to quantify it, but it seems as if the envelopes

Hi everybody, I am new in e1071 and with SVMs. I am trying to understand the performance of SVMs but I face with a situation that I thought as not meaningful.

Hello, I am currently using Samba 2.2.3a on a Sequent box running DYNIX/ptx v4.0. We are serving up approximatly 4.5 terrabytes of data from a Hitachi Data Systems storage array connected to our server by fiber channel. Many of our users are on Citrix which connects to our SAMBA server via a Gigabit Ethernet connection. There are still others that are connecting directly from their PCs which are
