•  ALP max scale

Please note that all of the ALP tests are functional testing, it is not meant to be for performance testing.

• If seeing unsuccessful connections, it could be due to the connection rate that the Server can handle.
  • Modify the config by reducing the connection rate to verify unsuccessful connections are also reduced.
    • The connection rate can be directly affected by setting the load profile to connections per time.
    • The connection rate can also be indirectly affected by increasing the frame size and ramp time.
  • If testing for high number of connections, o​​​nce the best connection rate is known, then the config can be adjusted for required number of connections and also appropriate ramp times.

HTTP_Connections

1. Setup 2 ports on different CCPUs
2. Create 1 HTTP client on one port and 1 HTTP server on the other port
3. Configure
   • Client Profile:
     • Disable pipeline option,
     • and leave other parameters as default 
   • Server Profile:
     • Change fixed body size to 8
     • and fixed response latency to 60000.
     • Leave other parameters as default 
   • Load Profile:
     • Connection test, 3 phases:
       • ramp up (stair: repetitions 1, height 4000, (height is number of connections, module dependent) 
       • ramp time 10s, steady time 0s), steady (stair: repetitions 1, height 0, ramp time 0s, steady time 60s),
       • and ramp down (flat: height 0, ramp time 10s, steady time 180s). Set the maximum open connections to 4294967295
   • Client: maximum transactions per server 10, Server: max requests per client 10
4. Start server and start client  

For HTTP CPS tests

1. Setup 2 ports back to back on different CCPUs
2. Create 1 HTTP client on one port and 1 HTTP server on the other port
3. HTTP Client
   • Disable Keep alive
4. HTTP server
   • Fixed Body size 64
5. Load Profile
   • Phase 1
   • Load Pattern = Flat
   • Load Type = Connections per time unit
   • Label = Ramp
   • Height = 800 (height is connections per second, module dependent)
   • Ramp Time =100
   • Steady = 1000
      

For Bandwidth tests use this text (although this is a bandwidth test, to get the most bandwidth is to set the Load Type to Connections)

1. Setup 2 ports back to back on different CCPUs
2. Create 2 HTTP clients on one port and 2 HTTP servers on the other port
3. Client Profile
   • Pipeline: enabled
   • Depth: 10
   • IP/TCP Receive Window Size Limit: 131072
   • Leave the rest at default
4. Server Profile
   • Change fixed body size to 32,768,000
   • Leave the rest at default
5. Load Profile
   • Phase 1
     • Steady time = 5 sec
     • Leave the rest at default
   • Phase 2
     • Load Pattern: flat
     • Height: 32
     • ramp time: 0s
     • steady time: 1000s or how long you want the test to run
6. On the devices grid
   • Client: maximum transactions per server: 16
   • Server: max requests per client: 16
   • Pipeline enabled, depth = 10
