Shown above, the test took 14.67 seconds to complete. Data transferred is the sum of data transferred to every siege simulated user. It includes the header information as well as content. Because it includes header information, the number reported by siege will be larger then the number reported by the server. In internet mode, which hits random URLs in a configuration file, this number is expected to vary from run to run.
Response time is the average time it took to respond to each simulated user's requests.
Throughput is the average number of bytes transferred every second from the server to all the simulated users. Concurrency is average number of simultaneous connections, a number which rises as server performance decreases. This error is usually caused by an improper termination of the program, siege was not given a chance to clean up after itself and it has an old IPC message still on the system. As you can see, there is a message queue still on this system. We don't want it there, so we will have to delete it.
