Application Performance
Using application-based statistics provides the most control over throughput and latency measurement. This
type of measurement is possible in peer clients.
An example follows. For more information, see Collecting Application Statistics.
Example:Transactions Per Second with Multiple Clients
The following VSD chart shows an application-dened statistic for the number of new order transactions executed
per second, aggregated over 180 clients. Each new order transaction consists of many statement executions. The
dip in throughput early on is caused by an application synchronization point.
The next chart shows the instantaneous latency for the stock level transaction as the elapsed transaction time
divided by the number of transactions for each sample. The average is 2.8 ms with a maximum of 7.18 ms. Each
