...guess). My problem is, is that not all 2TB hard drives are the same size (even though they should be 2 trillion bytes, there is still sometimes a +/- (I''ve only noticed this 2x so far) ) and if I create them mirrored, and one fails, and then I replace the drive, and for some reason, it is 1byte smaller, it will not work. How would I go about fixing this "problem"? ****THIS is just a thought, I am looking for thoughts and opinions on doing this... it prolly would be a bad idea, but hey, does it hurt to ask?**** I have been thinking, and would it be a good idea, to have on the...

...e if the following is true, but if we start sending a file to the same folder the such issue happen, the "hung" file will resume sending and complete immediately. The message file that we sent are usually in the sizes between 1MB-4MB. For the time being, we are sending small-sized file of 1byte to "trigger" and "hung" transmission. Below is the arguments that we are using RSYNC_ARG="--log-file=$LOGFILE --chmod=a+rwx,g+rwx,o+rwx --exclude=*.tmp --remove-sent-files --stats --ignore-times --whole-file -qr" There is no data loss but we encountered a long delay...

...nly 1 bit instead of sending the whole VAD/CNG packet. I am doing the same for AMR where i strip-off the AMR SID describing VAD/CNG and simply send "1 bit" in a custom appropriate header of the transmission protocol. With AMR 4.75, sample of 13byte, additionally i also cut-off the the 1byte AMR header by making AMR samples to be transmitted of 12byte. Are those kind of "bandwidth" optimization feasible also for speex? a) size of VAD/CNG samples being replaced by "1 bit" instead of transporting the whole sample b) cutting-off the speex header to reduce the sampl...

...e well under the 5x EfficiencySanitizer ceiling; presumably it should be under 2x. =========================== Heap/global object access patterns =========================== We plan to use shadow memory and sampling to keep track of heap/global object accesses. Shadow memory: We use a 4byte-to-1byte shadow mapping. Each application word is mapped to a - shadow byte, and so a 64-byte cache line is mapped to a 16-byte shadow memory. In each shadow byte, the highest bit is used for indicating whether the corresponding application word is accessed, and the other 7 bits are used a...

Interesting. Looking at vhost_can_busy_poll() it tries to poke pending vhost work and exit the busy loop if it found one. So I believe something block the work queuing. E.g did reverting 8241a1e4...
