Included are two similar programs in C and Java (/usr/green3/local.java/NIGHTLY1/jdk1.1/solaris/JDK1.1M-5).

The java version takes 443 times longer to run (far more than most comparisons)

The output of the two are:

ccode
ccount = 19990 took 210 milliseconds

java jcode
java count = 19990 took 93225 milliseconds


---------------------- The C code ---------------------------
#include <stdio.h>
main(int argc, char *argv[])
{
char buff[2000];
FILE *fd;
int count = 0;

clock();
fd = fopen("/usr/dist/share/lib/nameslistx", "r");
while(fgets(buff, 2000, fd) != NULL)
{
count++;
}
printf("ccount = %d took %d milliseconds\n", count, clock()/1000);
}


--------------------- The Java Code -----------------------------------
import java.io.DataInputStream;
import java.io.FileInputStream;
import java.util.Date;

class jcode
{
public static void main(String arg[])
{
long start = new Date().getTime();
try {
DataInputStream fs = new DataInputStream(new FileInputStream("/usr/dist/share/lib/nameslistx"));
int count = 0;

while(fs.available() > 0)
{
String line = fs.readLine();
count++;
//System.out.println("Line "+count+": "+line);
}
System.out.println("java count = "+count+" took "+(new Date().getTime() - start)+" milliseconds");
} catch (Exception e) {
e.printStackTrace();
}
}
