Hello,<br>
with drbd-8.0.14 or 8.0.16 on the same machines:<br>
My tests are "copy big files on the replicated device". This takes for
a file 8 seconds. instead of&nbsp; 0.2 seconds without drbd if kernel
version is 2.6.27 or 28 or 29. <br>
but with&nbsp; kernel 2.6.20 there is no performance problem:&nbsp; it takes
sensibly the same time to copy this file if drbd is running or not.<br>
I alway use the same drbd.conf for these tests.<br>
have you some ideas about why drbd is so slow with kernels 2.6.27 to
2.6.29?<br>
regards,<br>
Lise Didillon<br>
