Java multithreading reading a single large file

Question

What is an efficient way for a Java multithreaded application where many threads have to read the exact same file (> 1GB in size) and expose it as an input stream? I\'ve notice

Answer 1

you can open the file multiple times in readonly mode. You can access the file in any way you want. Just leave the caching to the OS. When it's too slow you might consider some kind of chunk based caching where all threads can access the same cache.
