MVA (Open) |
This tool uses
the Mean Value Analysis (MVA) technique to predict the average
response times and utilizations of system resources for open
systems. |
Updated July,
2008 |

Performance
Simulation
(Classic
Multi-Tier Information System)
|
This tool provides
a user interface to input hardware configuration-cum-topology
details, workload details and service demands to generate
an output file that can be directly run with Ptolemy's
Simulation Framework.
The output of such a simulation will be predicted values
of response time, throughput for each workload and system
resource utilization at each resource / server. View
