Say we have 20k-50k users signed up for an email newsletter. Does anyone have any data on how well ActionMailer does with mass emails? How long would that take to send? Anything I should watch out for? Thanks, Joe

Hi folks, I would appreciate it if someone can help me understand some weird results I''m seeing with trying to do performance testing with an SSD offloaded ZIL. I''m attempting to improve my infrastructure''s burstable write capacity (ZFS based WebDav servers), and naturally I''m looking at implementing SSD based ZIL devices. I have a test machine with the

I am wondering what the list's opinion is on the Apple to Intel switch. This is going to put a slick desktop that runs on top of BSD directly into the mainstream.

I''ve used mysql for quite some time now. Other than crashing when the partition gets full, I''ve had no problems with it. But I''ve heard great things about postgres and have seen some people say it''s much superior to mysql. So, with a Rails application, is there any reason why I would want to learn/use another DB besides mysql? Any pragmatic benefits?

Hi all, I have an average 2mbit multicast stream that once in a while bursts high (up to 20mbit/s) in short periods (about 200ms). Could anyone please help me with directions using tc for configuing leaky bucket shaping to this stream? I have a 5mbit/s ceiling. My system is running gentoo linux 2.6.14, and I have compiled in all QoS modules. Thanks. Oivind

Hi, A couple of points: 1) Font data, as in the actual font itself, doesn't really belong in an ogg stream. Given that it truly is "global" data in the sense that your fonts are shared by more than just a single ogg file, then the font should be separate from the stream and just referenced using an appropriate font naming scheme. If you meant font references in the first place,

This is a question about the use of the Cox proportional hazards model to analyze event histories. I am looking at the responses of sympathetic nervous system activity to a stimulus. The activity I observe is a burst that can only occur once per heart beat cycle (e.g., a binary count). Typically bursts occur in 60-80% of the heart cycles * sensory stimuli can modify these burst probabilities.

The new gem version dependency system from Rails 1.1.1 needed a few tweaks to work properly and to stop throwing meaningless warnings. This tiny release makes up for that. To install: * gem install rails * rake rails:update:configs (to get the latest config/boot.rb) This release also signals our new commitment to do more tiny releases from the stable branch, which only gets bug fixes. So it will

Did anyone else catch the redesign? I don''t know who''s responsible, but it''s lookin better!

Doja devices (NTT Mobile Phones) are very limited in their connectivity capabilities and was wondering if icecast can help me overcome them. The first limitation is that they only support HTTP that as I can see would not be a problem with icecast. The second limitation is that these Doja devices cannot transfer more than 150KB of data per HTTP connection so I can not simply establish one

Hi Philip, I'll do more testing and logging over the weekend and see how I go. At the moment I have 2.4.4 Win32 running on port 9000 @ http://radioinvercargill.nz:9000/ I'm not sure how good this will be from overseas as the queue is only about 8 seconds, burst about 4 seconds. It's adequate for xDSL/Fibre and 4G mobile over here and is on a 450Mbps upstream fibre line. I've

This is one of my test classes: class htb 1:10 parent 1:1 prio 0 quantum 2048 rate 160Kbit ceil 400Kbit burst 1803b/8 mpu 0b cburst 2111b/8 mpu 0b level 0 Q1: where does "level 0" stand for? Q2: where does this b/8 stand for? Q3: this is on a i386 platform, so timer resolution should be 10mS. According to the doc the minimal burst should be 10mS*160Kbit=1600. Why is it 1803? Q4: I

For those that missed out joining the amazing turnout of ~70 people here in Vancouver for the mini-workshop I did on the 27th last month, I am making available the 30 slides I used for the presentation. The slides were used in conjunction with me demonstrating it via command line. Alot was learned by both attendees, and quite possibly even more so by myself while teaching the material. I created

Hi, I''m a little confused about sessions. I have two objects, object "Apple" and object "Banana". These two objects have an N:M relationship. What I am doing is listing All of the Banana objects that are associated with a single Apple, then below that listing all of the Banana objects not associated with that same Apple. The user is then allowed to change the

Hi, Actually, I thought that Icecast did support seeking for static files. Of course it doesn't for a live stream. Geoff. ----- Original Message ----- From: "Thomas B.

Hi, I''m running Slackware 13.37 x86 using Shorewall 4.4.21 with OpenVPN and the VPN options I''m using in Slackware 13.37 will not work in Shorewall, but in Slackware 13.1 using the same Shorewall version and files, the ''interfaces'', ''policy'' and ''zone'', are all I have configured, it was working and this also works in Arch at

Hello, I have a request for an additional header. This header is needed to inform the client of the burst it is going to receive. Why ? This header could be very usefull for the streaming-client to have an idea of it's delay, and (much more important) to be able to do early-on streaming. The question is not on how to implement this in code (probably send the header in the

I posted earlier when I noticed that htb was releasing packets in pairs, even though my burst/quantums were 1 pkt. To fix I set HTB_HYSTERESIS 0 in net/sched/sch_htb.c . This gives a noticable gain in upstream worst case latency, for me with 256kbit/s up I used to see +90 sometimes, now it''s +45. For the many who have 128 up it should limit them to +90 rather than +180. Andy.
