In trying to debug xfstest 129 I noticed odd behavior to Windows server
test 129 does 4 steps, and the second one is the very slow step
$here/src/looptest -i 100000 -r -w -b 8192 -s
$SCRATCH_MNT/looptest/looptest1.tst
$here/src/looptest -i 10000 -t -r -w -s -b 102400
$SCRATCH_MNT/looptest/looptest2.tst
$here/src/looptest -i 50000 -r -w -b 256 -s $SCRATCH_MNT/looptest/looptest3.tst
$here/src/looptest -i 2000 -o -r -w -b 8192 -s
$SCRATCH_MNT/looptest/looptest4.tst
So the problem is the second invocation of looptest - when it is doing
10,000 102,400 byte sequential writes and reads passing in the
truncate flag. What I see in the network trace (at least to Windows
server) that is troubling is lots of "STATUS_PENDING" errors in the
write responses.
It appears that the test runs much faster to Samba
