That depends on what the bottleneck is in whatever configuration you're testing, and how you're testing it.

NAME
filebench - framework of workloads to measure and compare filesystem performance SYNOPSIS
/usr/benchmarks/filebench/bin/filebench profile /usr/benchmarks/filebench/bin/filebench -c stats_dir... DESCRIPTION
filebench runs workloads to measure and compare filesystem performance. Full documentation can be found at the performance community at: http://www.opensolaris.org OPTIONS
The following options are supported: -c stats_dir... Generates a HTML file (index.html) that is a comparison of the specified directories. stats_dir specifies the directory or directories in which the results are stored. OPERANDS
The following operands are supported: profile Specifies the name of the configuration file ending in .prof. The configuration file specifies: o what workloads to run, o what parameters to run, o the directory path on which to operate, and o the directory path in which to store the results. EXIT STATUS
The following exit values are returned: 0 Successful completion. 1 An error occurred. 2 Invalid command line options were specified. EXAMPLES
Example 1 Running the Multi-stream Sequential Read Workload The following example runs the workloads described in the configuration file named sqread.prof: # filebench sqread Example 2 Comparing Multiple Runs The following example compares the results of two previous runs. This example assumes that the results from the two previous filebench runs were located in the directories: /stats/wombat-zfs-noel- Jun_27_2007-15h_45m_33s and /stats/wombat-ufs-noel-Jun_27_2007-15h_52m_11s. This example generates a HTML file named index.html in your current working directory. # filebench -c /stats/wombat-zfs-noel-Jun_27_2007-15h_45m_33s /stats/wombat-ufs-noel-Jun_27_2007-15h_52m_11s ATTRIBUTES
