9 . The method of claim 1 , wherein, when performing the first task, each worker from the first pool sends a series of requests to the computer system at a specified rate.
10 . The method of claim 1 , wherein, when performing the first task, each worker from the first pool is configured to send a request to the computer system without waiting to receive a response from the computer system to a previous request.
11 . The method of claim 1 , wherein the at least one performance characteristic is selected from the group consisting of speed, latency, and combinations thereof.
12 . The method of claim 1 , further comprising providing the at least one performance metric to a client device of a user.
13 . The method of claim 1 , further comprising providing a worker module configured to act as an interface between the first pool of workers and the computer system.
14 . The method of claim 1 , further comprising:
implementing a second pool of workers on the plurality of nodes, each node comprising one or more workers from the second pool;
providing a set of instructions to the second pool of workers for performing a second task configured to interact with the computer system; and
employing the second pool of workers to perform the second task.
15 . The method of claim 14 , wherein the first task and the second task are performed in parallel.
16 . A system comprising:
one or more computers programmed to perform operations comprising:
implementing a first pool of workers on a plurality of nodes, each node comprising one or more of the workers from the first pool;
providing a set of instructions to the first pool of workers for performing a first task configured to interact with the computer system;
employing the first pool of workers to perform the first task; and
monitoring at least one performance metric associated with the computer system while the workers from the first pool are performing the first task.

18 . The system of claim 16 , wherein the plurality of nodes reside on a plurality of data centers.
19 . The system of claim 16 , wherein each worker from the first pool resides on a separate node.
20 . The system of claim 16 , wherein at least two workers from the first pool reside on a single node.
21 . The system of claim 16 , wherein the plurality of nodes comprise at least one director node and at least one worker node.
22 . The system of claim 16 , wherein the first task comprises sending a request to the computer system.
23 . The system of claim 22 , wherein the request is selected from the group consisting of a hypertext transfer protocol (HTTP) request and message queue (MQ) request.
24 . The system of claim 16 , wherein, when performing the first task, each worker from the first pool sends a series of requests to the computer system at a specified rate.
25 . The system of claim 16 , wherein, when performing the first task, each worker from the first pool is configured to send a request to the computer system without waiting to receive a response from the computer system to a previous request.
26 . The system of claim 16 , wherein the at least one performance characteristic is selected from the group consisting of speed, latency, and combinations thereof.
