Problem fixed, but there is some performance regression

ext3 (default)
untar		read		copy		remove
0m53.861s	0m24.942s	1m30.164s	0m20.664s
0m7.132s	0m1.191s	0m0.766s	0m0.076s
0m5.807s	0m3.345s	0m9.996s	0m1.719s

ext3 (-o barrier=1)
untar		read		copy		remove
0m52.117s	0m28.502s	1m51.153s	0m25.561s
0m7.231s	0m1.209s	0m0.738s	0m0.071s
0m6.117s	0m3.191s	0m9.347s	0m1.635s
