similar to: investigate & troubleshoot speed bottleneck(s) - how?

Hi I'm building new samba server (on Debian 6.0, software RAID10 2TB, Xeon CPU). Generally everything is working fine, so I have decided to run some stress tests. My choice was dbench. Old server is Debian 4.0 (samba 3.0.24, Athlon 3000+, one ATA 160GB disk). So run dbench 16 on both old and new server The results are strange old serwer: about 300MB/sek (dbench 3.0) and below are first

I've checked my interpretation against "flac -a" and it seems to read 17 bits for each warmup sample. Here is its output: frame=168 blocksize=4608

hello, I am now develloping an embeded decoding system for flac.I have a problem about the format of the rice coding: the residual begins with : 01 01 08 0C the first two bytes are the warmups, the prediction order is 2. and the 080C is the following: 00 0010 0000 001100 the first two bits mean: residual coding method is partitioned rice the following four bits mean: the partition order is 2 ;

Just add a 5vdc solid state relay ('cause you can't sink too much current out of the RS232C port). Substitute "2", "4" or "6" in the

Here's what I listed in that email. Merging doesn't appear to be necessary. If you have any build problems, let me know. Note that my detection code is Darwin-specific. It's a BSD call (sysctl()), so a change to the platform-detection macros should enable it to work on other BSDs. However, I don't know what that would be, and I couldn't determine any safe way to do the check

And warmup samples will be (17 - wasted_bits) bit. Voila, this was the source of all my frustration, sync problems and who knows what. My decoder now works correctly for files encoded with the default settings. Are

Hello you all, this is my first time on this forum because I recently started to learn this exciting "new" language and Frame stuff... anyway, I used to have Ruby 1.8.2 installed with Rails and I wrote some warmup applications on these. Yesterday I decided to update my Ruby and Rails... about 4-5 hours later I finished... it wasn''t easy but what is.. right? so I changed

Hi, I'm trying to write a FLAC decoder for my Java audio app. Can I ask a couple of questions to this list about the format? I think there are a couple of things not-quite-mentioned in the official spec. RICE CODING: Which order are Rice-coded numbers stored in? (a) [sign-bit][low-order bits]["k" zeroes][1] (b) [sign-bit]["k" zeroes][1][low-order bits] (c)

Hi list: I have been trying to get my feet wet with the ARM backend. As a warmup exercise I wanted to be able to move jumptables especially large ones out of the code section. Currently the idiom for jump tables loooks like this // .set PCRELV0, (.LJTI9_0_0-(.LPCRELL0+8)) // .LPCRELL0: // add r3, pc, #PCRELV0 // ldr pc, [r3, +r0, lsl #2] // .LJTI9_0_0: //
