Channel Types
Guaranteed Channels Implemented with Delayed Jobs. Uses a Database as process queue. Fast Channels Implemented with Starling. Uses a MemCache as process queue.

Performance Testing
Four different levels of message complexity Small - Integer - 3 Bytes Normal - Strings - 250 Bytes Large - Long Strings - 2.5 KB Huge - Long Strings - 25.5 KB

Testing Configuration
3 to 7 BEOCAT Nodes Types of Tests: 1 Sender - 1 Receiver 3 Senders - 1 Receiver 3 Senders - 3 Receivers
SLIDE 36
Testing Configuration
RestGate Server Running in Separated Node. 1 WebServer Instance 7 Worker Processes Running Tests were performed with both Guaranteed and Fast Channels

Guaranteed Channel Bottleneck
SLIDE 39
Testing Observations
Fast channels perform around 10% faster than guaranteed channels. Most messages are delivered in around 1 second. The sender spends at most 150 ms to make a delivery request.
SLIDE 40
Testing Observations
Messages with non string fields are slower to process. Memory usage was around 2 GBs of RAM At most 7 processors were ever active for more than 1 minute.
SLIDE 41
Testing Observations
Guaranteed channels start slowing down in a linear manner as message size and congestion increases. Fast channels exhibited a stable behavior
- n all test cases.
