More over, doing a CPU intensive task (like kernel comp.) (not involving LVM, the sources are not on a LV) cut the IO perf. of LVM fs by half. So it seems that the LVM is eating a lot of CPU on my system and this is what is limiting fs perf. DL -- Dominique Larchey LORIA, Nancy, France Tel. (Work) +33 (0) 3 83 59 20 13
