I really need to get 12Mbit/s out of this thing.
Easy. Do your math, with the variables being more or less
- buffer size for each queue entry - irq latency (can't be decreased below 1 uframe) - queue depth - 13 bulk packets of 512 bytes per uframe - 8000 uframes/sec What's the transfer rate for: - a queue with a single buffer, size maxpacket - or one buffer with buffer sizes of 4K, 16K, 64K - or N buffers of those four different sizes Or turn it around - What buffer size must a single-buffer queue use to get 12 MByte/sec? MBit/sec? The arithmetic shouldn't be any challenge. - Dave ------------------------------------------------------- This SF.NET email is sponsored by: SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! http://www.vasoftware.com _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
