Re: [MooseFS-Users] Transfer stats

[Aleksander W. <ale...@mo...>]

Hi
MooseFS in "Disk" tab shows transfer speed from system - not the direct
hdd speed.
Usually OS uses write-back cache to speed up writes. As a result if
there are not so many writes then in MFS stats you see "fake" write
speed because it's only speed of copying data to kernel write-back cache.
