ANALYSING AND EVALUATING I/O PERFORMANCE OF OBJECT-BASED FILE SYSTEMS
Pla Information · Computer Applications and Software · 2011
Currently,most of the object-based storage devices adopt universal file system such as EXT2 and EXT3 to manage,but are facing the problem of effectual storage and management against massive data.The object-based file systems realise to organise the objects in the disk area according to their size,and introduce the mechanisms of Hash and WorstFit,which improves the utility rate of the disk and observably raises its throughput rate at the same time.In this paper we test and analyse the I/O performances of EXT2,EXT3 and object-based file systems.Experimental results show that the I/O performance of the object-based file systems is two or three times of that of the EXT2 and EXT3.
