Re: Hi! Why having LSR's chunk size 2^n limitation?

filesystem could be another software that use devices (mysql innodb
engine, a oracle database direct at device level, a logical volume
manager...)

no, but....
you talk about a filesystem - device (md raid) feature
maybe you could get better performace configuring a different
filesystem, or another hard disk or flash memories, or another raid
configuration (1+0, 0 +1, 10, 0+5,0+6, 1+5, 1+6, x+y)

check source, round is for a easier (faster maybe less complex) code.

start at make you hardware faster with your linux
after
make your device faster with your filesystem (xfs, reiserfs, ext4???)
after
make you application faster with your filesystem (for mysql: myisam
with fixed table type is faster than dynamic table type and faster
than aria(mariadb) page table type)

  Roberto, thanks, but did I ask your advices?
