Take advantage of Multi-Core Processors and Multi-threading

[topblast]

I already gave you one. But the reason why the single threaded is a lot slower:

1 Thread:
msg = 1 ms
sleep = 50 ms
msg = 1 ms
sleep = 50 ms
msg = 1 ms
sleep = 50 ms
msg = 1 ms
sleep = 50 ms

2 threads:
msg-msg = 2 ms
sleep-sleep = 50ms
msg-msg = 2 ms
sleep-sleep = 50ms

As you can see, multi thread sleeps at the same time, single thread needs to do all the sleeps after each other. This meens that the sleep is the cause of the difference.

Test under heavy load (Phenom II x4):

If you redo the test without sleep (tickcount):

Multi: 0.122748

Also useless... 50 runs is not much..

Lets do 5k runs, and use cls to clean the screen so we can see the output.

Normal: 0.401239
Multi: 10.9652

This is better..

Lets do 50k runs:

Normal: 3.16472
Multi: 109.457

50k, make 2 threads max with multi threading:

Normal: 3.2298
Multi: 3.12841

A littel bit better

Now with 4:

Normal: 3.20476
Multi: 3.41695

Hmm, that sucks...

Without a heavy game that takes multiple threads:

50k

Normal: 3.8366
Multi: 3.384

5k

Normal: 0.427616
Multi: 0.335064

I guess you know enought now :P.

Please present the source for ur result so others can test.

I just replaced the tickcount code with the code I posted...
