Does multithreading give acceleration ?
I am trying to write a simple programm (Delphi) that will launch several threads and each of them will perform complicated calculations in a FOR cycle. The first from 0 to 500 000, the second from 500 001 to 1 000 000 and so forth. I see that several threads take MORE time than a programm without threads! Why so ? Why the system does't give my programm more processor time ? I can launch several copies of the programm without threads and will have what I want but... Have you ever tried to petform parallel calculations ? Where to dig ? Thank you)
