Elements of Performance
Transaction processing performance is measured by two elements: response time and
accuracy. PaymentNet's client/server architecture delivers superior performance against
both criteria, especially as throughput demand increases.
- PaymentNet's unparalleled response time is accredited to the
use of multiple threads and simultaneous processing (as opposed to serial throughput),
with our processing system optimized for transaction speed.
- PaymentNet’s accuracy is secured through monitoring
user connectivity throughout the transaction process; abandoned or disconnected sessions
result in abandoned transactions (not accidental payment). This level of user connectivity
monitoring is not possible using http-based solutions, giving a distinct advantage to
businesses using PaymentNet solutions.
PaymentNet’s Record
Our results speak for themselves. While we will guarantee round-trip transaction times
of less than 10 seconds, over 90% of our transactions are returned back to the client in
less than 3 seconds! PaymentNet is committed to add capacity as our (and your) transaction
volumes grow to maintain or improve transaction throughput.
Performance Measurements
Performance measurements are difficult on the Internet. The figure below shows the life of
a transaction and some typical transaction times for each step. By not only
designing our system for highest possible throughput, but also instrumenting the system
with performance monitors at both the client and the transaction server, PaymentNet is
able to assess our service performance in real-time and provide transaction performance
reports to our highest volume customers.
