I''m trying out rails 3 and I''m looking at the performance statistics given by WEBrick. It says many of my database operations are taking 2ms or 7ms... but the view is taking 40ms. People often say that the database is the bottleneck in applications (which it most certainly can be, and often is)... but isn''t the rendering of ERB a little show here? My test pages really aren''t that complicated... 1 partial... 1 layout... etc. T...

Yes, but this is java. You don't use any threading models and i dont know if you encode from sound card. I also don't know how optimized the code is.

CELP based coders perform poorly when you mix streams. Perhaps, we need a transform code or a subband code at somewhat higher rate 12-16 kbps that will retain the quality after transcoding and mixing. Is the speex ultra-wideband based on subband coding? -Devendra Jalihal <p>On Fri, 21 Nov 2003, Ulrich B. Staudinger wrote: > Hi, > been silent in this discussion for quite long ...

...believe this has something to do with the way my ISP has configured priorities at the telephone exchange. I begin to run in to trouble when I am uploading heavily on eth1 & ppp0 simultaneously. Once this happens, ping times over ppp0 rise dramatically, to well over 1200ms (normal is around 7ms). I have tried shaping on eth1 instead of ppp0 (as eth1 should contain all the packets for ppp0, I believe), but this does not yield lower latency, though I did note that it did limit the speed of the connection if I set the upstream and downstream values absurdly low. I think what I need to do...

Hi JM, I am using narrowband mode with speex qaulity set to 0 and complexity set to 4. The code works fine on the 3.2GHz processor. The test program speexenc takes 7ms to encode 5sec worth of voice on the 3.2Ghz processor. The same takes 700ms on the ARM5E intel Xscale. The code that I wrote puts 10 speex frames in one RTP packet. When exexcuted on ARM I get lots of underrruns hence noise. I was wondering perhaps its because of the speed of ARM processor as di...

Hello, I am preparing for upgrading from Debian Stretch to Buster. I am using Louis Van Belle's Samba packages. My current Samba version is: # smbstatus --version Version 4.7.7-Debian I can see that the Samba version that will be installed, when I upgrade from Stretch to Buster, will be the 4.11 since this is the current stable release... I would like to know if there are major changes

I am measuring the performance of one TCP connection over two symmetric paths. Packets are sent to two paths alternatively. I found that when the latency of each path are within 1ms, the overall TCP throughput is the *sum* of the throughput of the two paths. However, when the latency of the two paths increases to 5ms, the overal TCP throughput drops to the throughput of a *single* path. Has anyone

Sorry if this has been covered here somewhere in the past, but ... Does anyone know why logical vectors are *silently* recycled, even when they are incommensurate lengths, when doing logical indexing? This is as documented: For ?[?-indexing only: ?i?, ?j?, ?...? can be logical vectors, indicating elements/slices to select. Such vectors are recycled if necessary to match
