Abstract
A computer-readable recording medium recording a program capable of accurately analyzing the cause of a performance fault at the very end point of a client system, server system, etc. Outgoing and incoming packets are captured during execution of a communication application to measure a round trip time, and a communication window size of the transmitting source is estimated based on the captured incoming packets. A throughput estimate is calculated from the round trip time and the communication window size, and the estimated value and actual measured value of the throughput are displayed on, for example, a display, together with various other communication parameters including the communication window size and the round trip time, whereby the cause of a performance fault can be accurately located by quantitative analysis.
