similar to: Low-latency kernel?

By default asterisk (on my system) runs with NICE value "0" like most of the programs. Will the performance improve if I assign NICE value of let say -5 or -10 to asterisk? To my understanding it should as the priority will be higher than most other programs (it might even solve some echo problem). Am I right? How to start asterisk with priority let say -5? If I start the main process

I have 4 gig in my * box. I'm tuning for performance and I'd like to ask opinions: 1. asterisk -p == renice -20 ?? 2. I've turned off swap with no apparent ill effects. Can anyone commment on long term effects with moderate load (say, 30 SIP phones / 2-3K calls /day) 3. Can anyone comment on using ramdisk as swap and whether this is a good idea or bad idea? I'm using 2.6

Hello On my HP Compaq dc5800 with Ubuntu 13.04 and their 3.8.0-19-lowlatency kernel, I''ve got quite some kernel traces in the syslog. You can find them below or at http://pastebin.com/bLXPBX67 (to avoid line breaks…). These kernel traces all begin with: WARNING: at fs/btrfs/free-space-cache.c:921 __btrfs_write_out_cache+0x6b9/0x9a0 [btrfs]() Most of the time, it starts with: Call

Hello to everyone, I 'm trying to install wine 0.9.53 on my ubuntu hardy to get Guitar rig 2 right with lowlatency kernel. So i think this could be a right version.. I installed it with a .deb version ( i took it on this site) after i satisfied a dependency ( i think LIBLIP2: but i'm not sure...). But when i try to launch it from terminal this is the response: Application tried to create

Anyway, I figured it out. The extension was working, but Background() ignores the tones A through D by default. I didn't

I'm debugging a TxFax problem whereby the fax transmission fails. I suspect interrupt latency--some interrupt routine is holding its interrupt too long. I have all unnecessary services switched off and X is not running when I perform these tests. Some transmission are successful while others fail at random points. I've noticed that after I boot Linux, load zaptel, wcfxo, and wcfxs,

Hello, I use Asterisk 1.0.2 on a RedHat Enterprise Server 3.0 (Kernel 2.4.21) and i experienced that the memory consumption of the asterisk-process started by the init.d-script raises continously. Now, after 3 hours of operation (on our testing-system we have 30 concurrent connections to another asterisk box using IAX2 and GSM codec) there is already 66MB allocated. I think this could be ok, but

Hi, my primary monitor is a LCD HDMI2 and the secondary monitor is a CRT VGA1. The CRT monitor is only turned on on demand, but always connected by VGA. The BIOS is shown on both monitors, but the syslinux menu only on the CRT, as long as the CRT is connected by VGA. Even if it's turned off, the syslinux menu isn't shown on the LCD connected by HDMI.

At time to time somebody is trying "their luck" and send me most likely a junk fax on my voice line. During normal working hours is not a problem I just pickup the line and hangup the call but after-hours my voice mailbox is intercepting the call and recording those "beeps" (waisting my CPU cycles). Is there a way to block call / issue hangup command if the incoming call is a

Hi Jean-Marc, thanks for the response. First, I will clarify again that floating-point solves this - so isn't that a bug in fixed-point? Also, I understand that algorithmically the AEC won't cancel echo properly on a non-linear signal, but why completely distort the output? If the echo just won't get cancelled it would be acceptable, but in the current state it disables the ability to

Hi everyone, This is off topic and is for GS technical support really but it seems that there are a lot of Budge Tone 100/101/102 users out there. I've got a Budge Tone-100 (101 - without the extra 10base ethernet connetion?) here. I changed the configuration through its web based interface and I clicked the reboot link. But then something went wrong and ever since then it doesn't

For an office that is using VoIP phones to connect to Asterisk, is gigabit ethernet really necessary for the Asterisk box to connect to the switch? I know that I won't even approach the limits of 100 Mbps, but would gigabit help with latency / collisions when several calls are underway? The fact is, anything going outside the office will be over a data T1, so intuition tells me that 100

Hello I think, I somewhat destroyed my btrfs filesystem on my Ubuntu 13.04 kernel 3.8.0-25-lowlatency system. It got destroyed, because the system was hanging for some other reason and I had to remove power... When I try to mount my filesystem (there''s only one, with a few subfilesystems), the system crashes. Also btrfsck dies; always like this: a@ask-home:~$ sudo

Hi, I couldn't find a discussion that specifically addresses this, so here it is. I'm using Speex AEC in my mobile VoIP application to cancel speaker echo. The used version is 1.2rc1 from the website, and I'm compiling with fixed-point. On most occasions, the AEC works very well and cancels most of the echo (combined with the preprocessor). On some devices, where the microphone signal

Hi all, How do I add an asterisk representing a significant difference to a barplot? Cheers, Gil [[alternative HTML version deleted]]
