Nettet14. mar. 2024 · With frame-thread=2 the load was 100%. Increasing numa-pools over 48 did not increase CPU load or speed in FPS any further for me. Also when using standard numa-pools of 32 increasing frame-threads over 1 only seems to speed up the encode until a value of 2 as it can be seen that the encode with frame-thread 6 is a tad slower … NettetThere are 2 stacks: the kernel stack of the current thread (shares a single page with the TCB) and the kernel stack of the next thread.

Sometimes having more threads than LWPs, as can happen with unbound threads, is a disadvantage. For example, a parallel array computation divides the rows of its arrays among different threads. If there is one LWP for each processor, but multiple threads for each LWP, each processor spends time switching between threads. hca healthstream north florida

"Nettet18. feb. 2024 · JVMs can use a technique called escape analysis, by which they can tell that certain objects remain confined to a single thread for their entire lifetime, and that lifetime is bounded by the lifetime of a given stack frame. Such objects can be safely allocated on the stack instead of the heap. " - Linux bounded time frame threads
