协程栈分配优化问题 about photonlibos

[lihuiba]

It may lead to degraded performance in common case, if we delay the allocation of stack in thread_create() until insertion a thread into waitq, because that would incur memcpy() to move frames from old stack to new stack. Furthermore, the silent movement of the frames and the objects allocated in them would also incurs compatibility issues.

Photon already has thread pool that may solve your problem.

BTW,, variable-length stack is not on the list yet. I believe large-enough stacks can solve all the problems easily.

Get it. Thank you for your explanation. I will dive into Photon ThreadPool and then figure it out.
