https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D254763 --- Comment #6 from Mark Millard <marklmi26-fbsd@yahoo.com> --- (In reply to parv from comment #4) Intersting. Another comparison/contrast would be to try a fairly large file but one that would fit in RAM buffers/caching, say 4 GB based on your description, again both orders, with a PC reboot between. Going in a different direction . . . My vague memories lead to looking up: VBoxManage storagectl "VM name" --name <controllername> --hostiocache off Have you tried both hostiocache off and on? If I remember right on was a default. There might be more virtualbox settings that might contribute to how the I/O is handled. I do not remember much about such things. But such settings might be appropriate to explore for if they make any notable differences. --=20 You are receiving this mail because: You are the assignee for the bug.=
