My two coins:
# cat job
[global]
bs=8k
size=1g
direct=0
ioengine=sync
iodepth=32
rw=read

[file]
filename=/home/user/test

sync: 
READ: io=1,024MiB, aggrb=39,329KiB/s, minb=39,329KiB/s,
maxb=39,329KiB/s, mint=27301msec, maxt=27301msec

libaio:
READ: io=1,024MiB, aggrb=39,435KiB/s, minb=39,435KiB/s,
maxb=39,435KiB/s, mint=27228msec, maxt=27228msec

syslet-rw:
READ: io=1,024MiB, aggrb=29,567KiB/s, minb=29,567KiB/s,
maxb=29,567KiB/s, mint=36315msec, maxt=36315msec

During syslet-rw test about 9500 async schduledes happend.
I use fio-git-20070226150114.tar.gz

P.S. Jens, fio_latest.tar.gz has wrong permissions, it can not be
opened.
