It''s not about scalability on a huge site, but the lowest possible latency for a very small app. I have a little app with Thin and Sinatra. My app generates the page in about 50ms. After getting the browser request, thin waits 50ms and then it takes 300ms sending the page, to Chromium at localhost. (It takes 300ms to send a static a.html with the word "test" on it, too, so it seems to be a lower bound on my machine) Why is that? Should Mongrel be faster sending the data? Or maybe Passenger? The generating time was taken on Sinatra, by d...

hello, a friend of mine have this configuration: 10 x PC -- router/linux/rh8 -- ADSL Modem -- ISP let''s say that the bandwidth is: 5M and 800K he does dc++ and counter-strike, so let''s say the UP is full, and the ping from the counter server is 300ms, the server cut the connection, and no more game, the player is unhappy. The normal ping is 50ms. so he thinks to put some prio on the ping-echo packets to make the ping be extra small, he try the wondershapper from the lartc, don''t work, make a simplified script just for icmp with is: $...

Hi all, I'm having a problem with * being very finicky about the length of DTMF key-presses during menus, voicemail, etc. Basically, short (<100 ms) tones are ignored, anything between 100ms (or so) and about 300ms is correctly detected, and anything >300ms is interpreted as multiple presses of the same key. This is terrible for callers who are trying to get to the correct extension number, delete a voicemail message, etc. Any ideas why this is happening, or how to fix it? I searched the mailing list...

...XXXXXXX,1,Dial(SIP/gateway,,D(${EXTEN})) (this is a custom SIP gateway, which receives the DTMF's sent from softphones through Asterisk, and based on them, build the destination PSTN number). My problem is that Dial send the DTMF's to the SIP/gateway user at a rate of about 1 DTMF each 300ms. I'd like to know if it's possible to speed up that rate, or even, if it's possible to send the entire extension as a single DTMF string. Does anybody has a clue about how to do this? I was looking the options for the Dial command, and nothing like that appears on it. Thanks a lot...

I''ve been thinking a lot about running mcollective on my production servers recently, especially about its nice integration with puppet (using facts and so on). However I''ve got some concern about its scalability - how publish/subscribe middleware scales in terms of speed and flooding the network. I run about 2000 servers. Has anyone got any experience running mcollective on

...9;m using lowband 5.97 kpbs). However, when I tried to incorporate the jitter buffer feature, the latency would grow as time elapsed (up to a few seconds). I tried hacking the code by changing the SPEEX_JITTER_MAX_BUFFER_SIZE constant in jitter.c from 200 to 20 and the latency went down to around 300ms. Am I doing something wrong in my application code? Please advise. Thanks. Regards, Andy -------------- next part -------------- An HTML attachment was scrubbed...

...s the audio is fine. SIP-SIP calls sound good for both parties. Where should I setup the jitterbuffer? The zapata.conf (recent * 1.2) and/or the polycom configs (fw 2.0.3)? Any tips with the zap or polycom settings below would rock. Packet loss - average 7% --> ping test Latency - average 300ms -> sip show peers - latency ranges from 200-330 but stays within 10ms of initial value on ping test I tried to implement the jitterbuffer in zap. /etc/asterisk/zapata.conf jitterbuffers=16 ; covers the 300ms latency? 20ms each x16 = 320ms On the Polycom IP430's, I setup the jitterbu...

Hi Everyone, I know this is a recurring topic, but currently my application is running very slow and I would like to figure out why. Every transaction, except for the login page, have an average response time in the 8,000~ 14,000ms range (DB: 300ms range), which is absurd. I have implemented action caching and fragment caching on the views, but those only help when there is a cache hit. On a miss, it still takes 8+ seconds to load. I tried monitoring the application on new_relic and found out that my view takes up for nearly 90% of the loa...

Hi Carlos, How do you do? :) Can you please clarify the change introduced by the subj (http://boxster.ghz.cc/projects/nut/changeset/1289)? I need to know in particular why did you add these intervals between sending a command and reading the response. They are the root of weird problems with megatec_usb. Can I safely remove READ_PACE and usleep-s? I tried to search the archives and found the

...or is it kilobytes??) for the internet bandwith. i cannot use CRTP because i cant be sure if the ISP's routers are CRTP aware. Installing ADSL from ISP1 on the asterisk place will give a clear advantage Please correct any of my prior statements if wrong. should I maintain packet latency below 300ms or 150ms? How can I measure this latency all the way to the asterisk? Should I ping from SITE_A to the asterisk box with 8k packets? If I can't install ADSL for the moment, will the above setup work? thanks in advance for all your help. Erick.

...o, I am very slowly working on the NHW Project.I recently made a speed comparison with x265 and wanted to share it with you. On my processor Intel Core i5-6400, in average the NHW encoder (totally unoptimized) is x10 times faster to encode than x265 (png decoding time removed), in average 30ms vs 300ms for a 512x512 24bit color image, and in average the NHW decoder (totally unoptimized) is x3 times faster to decode than x265 (output to .ppm file), in average 10ms vs 30ms. As a reminder, x265 is ultra optimized, so with good C optimization, SIMD optimization and multithreading, the NHW codec will...

I recently read about the following new technologies from Digium. Has anyone tried the new HPEC or knows when it will be available? TDM800P and HPEC The TDM800P is an 8-port analog telephony interface card, so it fills the gap between Digium's 4-port and 24-port cards. Analog phones and POTS lines are going to be with us for some time, and demand for support for them remains high. The

...my PC verified that indeed there really was a broadcast storm happening that was triggering this. The capture showed that upon startup Samba 4.9.0 was sending thousands and thousands of broadcast packets onto the wire in very quick succession. Wireshark counted around 6500 broadcasts in about 300ms. The packets are all Host Announcement packets sent from the IPv4 address of the host to the broadcast address of the subnet the Samba is on. Upon reverting back to 4.8.5 with no other config changes, everything is back to normal again. The config is very basic: thunderstorm ~ # testparm Load...
