Getting sense of ephemeral store behavior under OpenSolaris (UFS,ZFS)

To get impression of ephemeral store behavior under OpenSolaris (UFS,ZFS) I use bonnie++, compiled from source with debug output. Pre-compiled binary can be get from [www.sunfreeware.com SunFreeware]

This entry is part of ‘OpenSolaris on Amazon EC2′ workshop

I will skip file based tests and use large file pool test only with size configuration more then 2x of instance memory, because main purpose of test is evaluate “Amazon EC2 documented ephemeral storage feature fist access can be significantly slower “.
