Hi list, i found a strange ext4 (?) effect. when i write to a disk: dd if=/dev/zero of=xx bs=1G count=1
reports 2.6 GB (expected) doing again speed drops to 200MB. removing xx restores old speed. I ask the net and it seems that the effect is there since kernel 2.6. I found the explainations a bit confusing. does anyone know more ? note: i was analysing a performace issue for mysql and i am not sure if that problems matters outside tests. re rp _______________________________________________ Dng mailing list [email protected] https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
