Abstract

A method for optimizing enterprise server resources in a computer system is described. The method comprises monitoring at least one metric of the computer system capable of indicating a performance level thereof; determining whether the performance level needs to be improved; and responsive to a determination that the performance level needs to be improved, implementing a best method to improve the performance level by adaptively manipulating one or more threads in a pool of threads in the computer system.

Claims

1. A method for optimizing enterprise server resources in a computer system, comprising:

monitoring at least one metric of the computer system capable of indicating a performance level thereof;

determining whether the performance level needs to be improved; and

responsive to a determination that the performance level needs to be improved, selecting and implementing a best method to improve the performance level by adaptively manipulating one or more threads in a pool of threads in the computer system.

2. The method of claim 1 wherein the monitoring at least one metric includes checking CPU utilization of all threads of the computer system.

3. The method of claim 1 wherein the monitoring at least one metric includes checking a latency of mail processing.

4. The method of claim 1 wherein the monitoring at least one metric comprises checking responsiveness of all threads.

5. The method of claim 1 wherein the determining comprises:

generating at least one statistical parameter for each of the at least one metric; and

examining the generated at least one statistical parameter for each of the at least one metric.

6. The method of claim 5 wherein the at least one statistical parameter is selected from at least one of a statistical average, a mean, a highest use, and a standard deviation.

7. The method of claim 1 wherein the best method includes creating a new thread pool and assigning users to that pool to isolate the assigned users from other users.

8. The method of claim 1 wherein the best method includes creating more threads in a same pool to reduce latency.

9. The method of claim 1 wherein the best method includes creating additional threads in a thread pool selected from a plurality of thread pools.

10. The method of claim 1 wherein the best method includes permanently assigning threads to respective users.

11. A system for optimizing enterprise server resources in a computer, the system comprising:

means for monitoring at least one metric of the computer capable of indicating a performance level thereof;

means for determining whether the performance level needs to be improved; and

means responsive to a determination that the performance level needs to be improved for selecting and implementing a best method to improve the performance level by adaptively manipulating one or more threads in a pool of threads in the computer system.

12. The system of claim 11 wherein the means for monitoring at least one metric includes checking CPU utilization of all threads of the computer.

13. The system of claim 11 wherein the means for monitoring at least one metric includes checking a latency of mail processing.

14. The system of claim 11 wherein the means for monitoring at least one metric comprises checking responsiveness of all threads.

15. The system of claim 11 wherein the means for determining comprises:

means for generating at least one statistical parameter for each of the at least one metric; and

means for examining the generated at least one statistical parameter for each of the at least one metric.

16. The system of claim 15 wherein the at least one statistical parameter is selected from the at least one of a statistical average, a mean, a highest use, and a standard deviation.

17. The system of claim 11 wherein the best method includes creating a new thread pool and assigning users to that pool to isolate the assigned users from other users.

18. The system of claim 11 wherein the best method includes creating more threads in a same pool to reduce latency.

19. The system of claim 11 wherein the best method includes creating additional threads in a thread pool selected from a plurality of thread pools.

20. The system of claim 11 wherein the best method includes permanently assigning threads to respective users.

21. A computer system comprising:

a host computer; and

redirector software executable on the host computer, the redirector software for redirecting data items of a user to the user'"'"'s mobile data communications device (“

MDCD”

);

wherein the host computer monitors at least one metric of the computer system capable of indicating a performance level thereof, determines whether the performance level needs to be improved, and responsive to a determination that the performance level needs to be improved, implements a best method to improve the performance level by adaptively manipulating one or more threads in a pool of threads in the computer system.

23. The computer system of claim 21 wherein the best method is selected from at least one of creating a new thread pool and assigning users to that pool to isolate the assigned users from other users, creating more threads in a same pool to reduce latency, creating additional threads in a thread pool selected from a plurality of thread pools, and permanently assigning threads to respective users.

22. The computer system of 21 wherein the at least one metric is selected from at least one of CPU utilization of all threads of the computer system, mail processing latency, and responsiveness of all threads.
