Caveats of select/poll vs. epoll reactors in Twisted
...eed. Of course, for such small numbers of sockets, both mechanisms are so fast that you don't really care about this difference in the vast majority of cases.

How to pass parameters correctly?
... could also argue that for fundamental types or types for which copying is fast, such as int, bool, or char, there is no need to pass by reference if the function simply needs to observe the value, and passing by value should be favored.

What is the best way to use a HashMap in C++?

Lookups, which cannot change the size of the table, are generally much faster. As a result, most hash-based tables tend to be at their best when you do a lot of lookups compare...
