[Glass] RAID5 configurations

[Dario Trussardi via Glass]

Ciao,

	i do some test for RAID5 performance.

	I have testing with chunk size of 512KB   and with chunk size of 8KB.


	I run the code: 

 		[ 1 to: 10000 do:[ :int | UserGlobals at: #Scandella put: (( UserGlobals at: #Scandella ) +1).
							System commit ]] timeToRun.

	obtaining the same execution time.

	Is not strange ?

	With the chunk of 8KB i will expected better performance.

	Dario
