Re: Slow network?

You might also want to replace those 'pass' statements when smartqueue is empty or full with time.sleep() to avoid busy waiting. I misunderstood your post, sorry. My smartqueue class has a timeout parameter, and it can block for an item, or raise the Full/Empty exception after timeout exceeded

Re: Slow network?

You might also want to replace those 'pass' statements when smartqueue is empty or full with time.sleep() to avoid busy waiting. It won't do busy waiting, because read_str and write_str are using select.select and they will block without using CPU time, until data becomes available to read/wri

Re: Slow network?

It is very likely that nodelay is actually hurting you here. Using the select module and doing non-blocking IO will be faster than using threads for this as well. These sockets are non blocking and I'm using select.select indeed. Here is how it is implemented: def read_data(self,size): re

efficient interval containment lookup

hello, suppose I have two lists of intervals, one significantly larger than the other. For example listA = [(10, 30), (5, 25), (100, 200), ...] might contain thousands of elements while listB (of the same form) might contain hundreds of thousands or millions of elements. I want to count how many i

Slow network?

Hi All, To make the long story short, I have a toy version of an ORB being developed, and the biggest problem is slow network speed over TCP/IP. There is an object called 'endpoint' on both sides, with incoming and outgoing message queues. This endpoint object has a socket assigned, with n
