Server Performance Testing

  • Print
  • Dark
    Light

These tests were done on an i7-3770 Processor with 16gb of ram.  The Ram in the server process never went above 500 MB, however. Tests were observed to ensure the processor was fully utilized. 
Tests were run on Decisions Platform Build 3.0.0 rev 15933M
In tests involving the database, we did not assume the same linear scaling that the flow engine experiences.
Putting work into work queues will cause some additional overhead as a process requires a save, and this was not tested in this series of tests.
Note: Production system performance may vary based on a number of different factors including:

  • server being used for other purposes
  • any network latency in calls
  • speed of database server and database storage
  • the actual steps used in a process. An example of this would be a steps like: making an assignment, creating a pdf, running a database query or sending an email - all of which require either heavy processing or external system interactions.

Flow Performance

Flow Execution

10,000 Full Flow Executions/Second/Processor

Flow Execution Manipulating Data In List

This flow creates a list, creates and adds 50 items to it (104 step executions total).
1923 Full Flow Executions/Second/Processor
x 3,600 seconds
x 8 processors
55,382,400 flow executions/hour/server

Flow Start with Assignment

  • Note, This test was constrained to 2 processors given the limitations of the database that was being tested against.  This test was not designed to test the scalability of the database but to test the overhead the workflow engine added in putting items into it.
