...(4 E1's) with ISDN protocol and I need to find out if there is any limitation about DSP capabilities, I mean, I am not sure how many phone calls my Digium card supports, simultaneously. The calling flow goes from IAX <-> ISDN. I am running this card into CPU like this: - Micro PIV 3.0 - 1Gbyte Memory Thanks.

Hi, Sorry if this is well known. Suposse I am transferring a large (by now) file, say 1Gbyte with --partial: rsync -e ssh -a --partial 1gbfile server: If process is interrumpted, temporary file is renamed to good filename with size samall than original, say 400Mbyte, ok. If from client I do again the same command, then, in server the 400Mbyte file is COPIED to another temporary file, b...

...setup where the nodes are RHEL5.1(with the latest 5.2 kernel), when i try to write NFS data, the nodes scale linearly until they reach the 10th node, that is the bandwidth , and throughput seen from the NFS sever on the other side of the nodes shows a liner increment from around 100+Mbyte/sec up to 1Gbyte/sec, however when we add another extra node to the equation the bandwidth/throughput becomes erratic/inconsistent, and drops to around 500-700Mbyte/sec. however if i try the same setup with RHEL4U6 i do not get the same behaviour it sustains the bandwidth at 1Gbyte/sec. the setup is like this 48 no...

...nt. We will be adding some Windows machines sooner or later with 10Gbit interfaces. We are seeing 100-150MBytes/sec read or write performance between the Mac and the FC13 system over 10Gbit interface but it should be capable of 400-500MBytes/sec. We have a local raid on the FC13 system that runs 1GByte/sec locally using an Areca 1880-ix-16 raid card (6Gbit version). It has 16 fast Hitachi disks in a Raid5 format using xfs filesystem. The problem here is that samba is poking the Areca at 128KByte I/O's on preads and writes, i.e. shown to us using strace on the smbd daemons that are running....

...t. I will move to checking the CVS Cygwin build once the groff error is solved. I believe I found another error in the post 1.5 "fork" CVS before the 1.5 release :( Thanks for solving that. I do not mind doing the Cygwin builds, although I wish I had updated the RAM on this machine to 1GByte as the whole build process takes over three hours. It would be good to workout how to do non-debug builds as that would speed up the linking, which is particularly slow. I don't want to be a slave driver but any thoughts on the groff error ???:) Aaron

...es and 500 concurrent listeners all using low-bitrate 16kpbs streams. I'm experiencing some connection losses at these peak times ("Client connection died" message in error.log). The machine running Icecast has a 100Mbit connection to the internet. It is a Celeron 2.4Ghz machine with 1Gbyte of main memory. The CPU load at these peak times is normal at 0.4 (40%), the load is relatively high, averaging out at 0.4 with occasional peaks to 5.0. I've analysed the ethernet packets on some of the listeners connections and found that Icecast sends many small packets (200-300) bytes. This...

Actually, I just found out why. Remove the space from the end of the TOOLNAME line in llvm-ar and llvm-ranlib Makefiles. This is what's causing it, there's a space between "llvm-ar" and ".exe" I'll patch the makefiles when UIUC's CVS server isn't so sluggish.

...nations. Can somebody help me? I have several sites that rely on a central server for connection to the PSTN. Calls to the PSTN are routed over the Internet to this PSTN gateway using IAX2 in trunk mode. To minimize bandwith usage, the Speex codec is used. The central PSTN gateway is a P4 3.0GHz, 1GByte mem, has a TE110P card supporting ISDN30 and runs Asterisk version 1.0.3 on Debian Sarge. While sustaining 5 connections dialed in through the TE110P (terminated at remote sites through IAX) and running top on the PSTN gateway, I see 98% CPU idle time most of the time. I also see short (around 10s...

Hi all, Currently we have severe problem and are struggling to investigate it. The problem is data broken. Reproduce pocess is following, 0. test FTP function between guest domain and FTP client(other PC). 1. put data from FTP client to guest domain. 2. get data from guest domain to FTP client. 3. compare put data and get data on FTP client. 4. repeat process from step1 to step3.

I created a fresh new rails app, no gems, no nothing. Completely unmodified. Doing anything that initializes rails takes 2 - 3 times longer in ruby 1.9.1 than it does in 1.8.7. Obviously with a fresh rails app, this is only 2 - 3 seconds extra. But with a decent sized app, this can take up to 25 seconds for rails to initialize, vs the 12 seconds in 1.8.7. I''ve been racking my brain on

To do a release build, just do: make ENABLE_RELEASE=1 that's all ther...

I hope this is merely a FAQ, and not an AFAQ (annoyingly....). I'm a SAS programmer, with several years' experience of the system, evaluating alternatives. See the SAS for Linux website (URL in sig) for more info. I'm exploring R's capabilities and limitations. I'd be very interested in having a deeper understanding of it capacity and performance limitations in dealing with

Hi Jan, I asked almost the exact same question as you about 6 months ago and someone provided some Gen4 results for me (But I can''t seem to find them in email), they were a fair bit better than Gen3. With IPOIB, you want connected mode and a large 32Kb+ MTU for max bandwidth, 1Gbyte/sec or more should be possible with Gen 4. Here are some of my original test results on my Opteron System with Gen3 cards: #qperf 192.168.10.160 tcp_bw tcp_lat tcp_bw: bw = 866 MB/sec tcp_lat: latency = 30.8 us # qperf 192.168.10.160 rc_bi_bw rc_bi_bw: bw = 1.71 GB/sec T...
