2.6.38-std-def-alt2:
[ 1.130351] io scheduler noop registered
[ 1.130485] io scheduler cfq registered (default)
2.6.32-ovz-el-alt14:
[ 0.989534] io scheduler noop registered
[ 0.989646] io scheduler anticipatory registered
[ 0.989761] io scheduler deadline registered
[ 0.989904] io scheduler cfq registered (default)
2.6.32-el-smp-alt19:
io scheduler noop registered
io scheduler anticipatory registered
io scheduler deadline registered
io scheduler cfq registered (default)
А, может, и не в el дело, а в 2.6.32. В 2.6.32-ovz-smp-alt7
LA тоже около 3 держится. По шедулеру:
[ 1.230933] io scheduler noop registered
[ 1.231235] io scheduler cfq registered (default)
Везде, вроде как, cfq получается.
