Java: Efficiency of the readLine method of the BufferedReader and possible alternatives
- by Luhar
We are working to reduce the latency and increase the performance of a process written in Java that consumes data (xml strings) from a socket via the readLine() method of the BufferedReader class. The data is delimited by the end of line separater (\n), and each line can be of a variable length (6KBits - 32KBits). Our code looks like:
Socket sock = connection;
InputStream in = sock.getInputStream();
BufferedReader inputReader = new BufferedReader(new InputStreamReader(in));
...
do
{
String input = inputReader.readLine();
// Executor call to parse the input thread in a seperate thread
}while(true)
So I have a couple of questions:
Will the inputReader.readLine() method return as soon as it hits the \n character or will it wait till the buffer is full?
Is there a faster of picking up data
from the socket than using a
BufferedReader?
What happens when the size of the input string is smaller than the size of the Socket's receive buffer?
What happens when the size of the
input string is bigger than the size
of the Socket's receive buffer?
I am getting to grips (slowly) with Java's IO libraries, so any pointers are much appreciated.
Thank you!
