Unified Performance Tool (or uperf for short) is a network performance tool that supports modelling and replay of various networking patterns. It represents a new kind of benchmarking tool (like filebench) where instead of running a fixed benchmark or workload, a description (or model) of the workload is provided and the tool generates the load according to the model.

Unified Performance Tool (or uperf for short) is a network
|
|
performance tool that supports modelling and replay of various
|
|
networking patterns. It represents a new kind of benchmarking tool
|
|
(like filebench) where instead of running a fixed benchmark or
|
|
workload, a description (or model) of the workload is provided and
|
|
the tool generates the load according to the model. By distilling
|
|
the benchmark or workload into a model, you can now do various
|
|
things like change the scale of the workload, change different
|
|
parameters, change protocols, etc and analyse the effect of these
|
|
changes on your model.
|
|
|
|
Some of the questions you could answer using uperf are:
|
|
* Bandwidth and latency (unidirectional and bi-directional) with different
|
|
protocols like TCP, UDP, SCTP, SSL
|
|
* Connection setup and teardown scalability for different protocols
|
|
* Effect of noise on ongoing network connections
|
|
* Does it matter if I use processes instead of threads to do network
|
|
communication?
|
|
* What is the L2 cache miss rate for connection setup?
|
|
* Is sendfilev(3EXT) (with one file) equivalent to sendfilev(3EXT)?
|
|
* Understand TCP, UDP, SCTP, SSL performance under a variety of conditions
|
|
* Test various TCP Congestion control algorithms
