...anyone do some work on improving the samba read/write performance? We've got a board attached with an IDE hadisk, running samba 2.0.7 on uClinux(NOMMU) OS, the IDE throughput: 10.5Mbps,ethernet speed: 16Mbps,Samba throughput(copy file from WINDOWS PC to host board ): 600KByte/s,CPU working at 120MHz, system SDRAM 16Mbyte. Could anyone help to figure out where the bottleneck is and how to tune it? Thanks a lot! Happy hacking... hn _________________________________________________________ Do You Yahoo!?

...peex for implementing a VoIP demo application using linphone on an embedded system. At the moment I'm not really able to do real time encoding, and thinking about making an assembler port for speex to the AVR32 architecture. The AVR32 is a new hybrid MCU/DSP fixed point processor running at 120Mhz in my application. Does anyone have experiences/info about the computational power requirements, e.g. what quality/bitrate and complexity of encoding seem to be realistic as target operating modes. I've run some tests with speexenc, encoding a 1minute 16bit PCM 8khz speech file, which took 3...

Thanks for fast answer. I would like to hold 4 analog channels or 4 digital channels, voice mail with this system. I read that it's necessary 30 MHz per channel. Is it true? In this case, I will need 120MHz. Luis >>I would like to know what are the minimum hardware requirements for >>Asterisk: >>1. Linux kernel 2.4? >>2. PC 486 50MHz? >>3.

Just a thought If the I386 (or i686, never could figure out why the name change) disk doesn't quite fit on the DVD+, and needs a DVD-, this might put some folks at an inconvenience. I wonder if the difference between fitting and not fitting is small enough, so that some amount of pruning might make it fit on the DVD+R image. Some ways to prune could be: a) Create two versions of the

Greetings, I've just started porting speex to a TI C5509 DSP. It doesn't look like it's going to be too painful, but there are a couple of quirks about the C5x. 1) chars are 16 bits because memory addresses are for 16bit words 2) ints and short are also 16 bits (so sizeof(char) = sizeof(short) = sizeof(int) = 1) 3) the c5x is essentially big endian My plan is to change int and

Hi All: I'm running Mandrake 8.1 (downloaded) and the install went fine. Configuring Samba however is another story. I get the message "could not connect to host - localhost" on the Linux box. I cannot see the network from the Linux system. The Linux system is visable from Win'98SE as are the shares but I cannot access them "password is incorrect". This does not
