There are a couple To test the performance of steps you must perform to be able to use various storage solutions for the NFS share on hong kong[[Fedora ARM Secondary Architecture/ARM hardware|ARM hardware]] devices.
1. Edit your "/etc/fstab" and change the following lines file system to "auto" from "nfs""/dev/root / nfs defaults 1 1"= Performance Results =
2. Use yum to install "rpcbind" and "nfs-utils" and make sure that the "rpcbind" and "nfs" services are started at boot.===USB PATA===

5. If it mounts correctly it will give no output. Run the "mount" command to check that it has been successful.===iSCSI===
6 Version 1. Add the following line to "03e ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks-- Machine Size K/etcsec %CP K/fstab" to auto mount the share every time the VM bootssec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP fedora-arm 2G 4923 82 31503 30 1827 3 5537 96 59147 84 2514 44 ------Sequential Create------ --------Random Create-------- -Create-- --Read--- -Delete-- -Create-- --Read--- -Delete-- files /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP 16 11785 92 +++++ +++ 21841 99 12533 98 +++++ +++ 21201 100 fedora-arm,2G,4923,82,31503,30,1827,3,5537,96,59147,84,2514.5,44,16,11785,92,+++++,+++,21841,99,12533,98,+++++,+++,21201,100

7. Reboot your vm to make sure the nfs share is properly mounted at boot. To restart your vm log into hongkong as root and run the following commands. As an example i will use arm-001-002, replace this with your VM.=== Write ===
