System and method for managing system resources in a network environment

A computer program product, comprising a computer-usable storage medium having a computer-readable program code stored therein, said computer-readable program code containing instructions that when executed by a processor of a computer system implement a method for managing system resources in a network environment, said method comprising:

• reading from a first log both timestamp Ti and actual response Ri for i=1, 2, . . . ,I, said Ti comprising a timestamp corresponding to a request to utilize said system resources, said Ri comprising a length of time necessary for said system to respond to said request, said Ri being expressed in dimensionless units, said I corresponding to the total number of both said timestamps and said actual responses residing in said first log, said I being a positive integer having a value greater than 1;
• and
• for each combination of both timestamp Ti and actual response Ri for i=1, 2, . . . ,I, where Ri does not equal zero:
• calculating a number active threads AT(Ti+j) in said system at time Ti+j for j=0, 1, . . . ,Ri−1, according to a function AT(Ti+j)=AT(Ti+j)+1, said AT(Ti+j) comprising the total number of threads active at time Ti+j;
• and
• storing AT(Ti+j) for j=0, 1, . . . ,Ri−1, in a second log, said second log comprising both timestamp Ti+j and AT(Ti+j).

A computing system comprising a processor coupled to a computer-readable memory unit, said memory unit comprising a software application, said software application comprising instruction that when executed by said processor, implement a method for managing system resources in a network environment, said method comprising:
