最近要幫user把一台FreeBSD P2V進VM中,因為有近200GB的資料也得一併P2V(user端沒有NAS,只有server上才有RAID
),鵝先在一般機器上測試(i.e. AHCI+SATA),沒想到原來的source disk不論是以RDM或是透過IOMMU/VT-d讓guest直接抓到實體HD,copy到guest所在的vmdk時都只有1.xMB/sec左右(鵝知道小檔一多throughput一定好不起來,但這也太流汗了點
),但是source/destination同在實體HD上時throughput又還好(3年多前的2.5" 5400rpm HD好歹還能跑出1xMB/sec
),請問一下要怎麼搞才有搞頭啊![Orz]()
