benchmarks

Dev Center

All the benchmarks were conducted using the following hardware/software configuration:

  • Dual Core i5 2.53 GHz
  • 32 bit Windows OS
  • 4 GB RAM
  • L3 cache 3.0 MB
  • Windows 7 Home Basic
  • java version “1.7.0_05″
  • Java HotSpot(TM) Client VM
  • JVM arguments -Xms1G -Xmx1G -XX:NewRatio=1
  • Clients and server are connected via 100 Mbps LAN
  • No server side adaptors (custom code extensions) are set

All computers were connected in the same local network through a 100Mbps LAN.

Private Message Test Light

Each client connects to a zone. It then sends a private message for user with same name as itself. So each message sent will generate a response and notification back to the client. Each client sends at a low rate of 1 message every 10 seconds and receives at a double rate (2 msg/10sec).

Beyond this the server accepts connections at a slow rate.

Private Message Test Medium

Each client connects to a zone. It then sends a private message for user with same name as itself. So each message sent will generate a response and notification back to the client. Each client sends 1 message every 2 seconds and receives at a double rate (1 msg/sec).

New Connections are made at a rate of 100/sec.

CCU: 5000

  • In: 2500 msgs/sec
  • Out: 5000 msgs/sec
  • CPU: 7%

CCU: 10000

  • In: 5000 msgs/sec

  • CPU: 15%

CCU: 15000

  • In: 7500 msgs/sec
  • Out: 15000 msgs/sec
  • CPU: 26%

CCU: 20000

  • In: 10000 msgs/sec
  • Out: 20000 msgs/sec
  • CPU: 35%

CCU: 25000

  • In: 12500 msgs/sec
  • Out: 25000 msgs/sec
  • CPU: 70%

CCU: 30000

  • In: 15000 msgs/sec
  • Out: 30000 msgs/sec
  • CPU: 75%

Upon increasing the CCUs at this rate, the connections started to break.

Private Message Test Heavy
