Welcome to Russians Lab for the Cats Preparation

This is git repository (respect to Linus Torvalds) containing a number of code examples for researching input/output subsystem implementations in different computer languages (compilers and interpreters).

Due to very small size of the tested code examples, it is quite fair to compare compilers and interpreters in the single test set.

Currently, we explore how native I/O operations work for each system under examination on re-implementation of the GNU cat utility.

For the sake of performance, if it's possible, we use functions which operate on big blocks of data.

Utility strace or its analogs can be used to explore system calls of executing programs.

To analyze computation systems based on virtual machines with bytecode execution (e.g. JVM, BEAM, Parrot), a command strace can be called with the -f flag.
