Hi,

I have a algorithm which loops over a set of 100 million sets of 3
values in a tight loop. eg;

while(1){ //do forever until terminated
BufferedReader in = new BufferedReader(
                            new FileReader(
                                    "ratings.txt"));
    for(i=0;i<numSets;i++){
        int value1 = Integer.parseInt(in.readLine());
        int value2 = Integer.parseInt(in.readLine());
        int value3 = Integer.parseInt(in.readLine());

        //do some stuff with the values here....
    }
}

I was hoping that someone might be able to suggest whether that can be
optimised in terms of speed.
I can format the values in the file in any way, I have tried fixed
width fields, but the file gets significantly bigger due to the
padding. I tried loading the file into memory, but I don't have the
ram. (the file is 1.6GB like that)

Thanks,

T.
