Hmm, not sure if anyone else tried this, but I wrote a quick Java class that
uses the FileInputStream class to read a file. I read a 126 meg file that
took about 700ms using CFFILE in CF5, but took around 2000ms using the
class I wrote.
Win 2K Pro, Athlon XP 1800+, 512 megs RAM, 40 gigs HD space. JDK 1.3.1_01
If anyone else wants to try:
Java class:
import java.io.*;
public class FileLoader {
FileInputStream fileInputStream;
byte[] fileStream = new byte[100000000];
int fileLength;
public FileLoader(String fileName) {
try {
fileInputStream = new FileInputStream("e:\\" + fileName);
fileLength = fileInputStream.available();
while (fileInputStream.available() > 0) {
fileInputStream.read(fileStream);
}
} catch(Exception e) {
System.out.println("An Error Occured.");
}
}
public int getFileLength() {
return fileLength;
}
public static void main(String args[]) {
FileLoader fileLoader = new FileLoader("dot net sdk.exe");
System.out.println(fileLoader.getFileLength());
}
}
CF Code:
<CFSET tickBegin = GetTickCount()>
<cffile action="READBINARY" file="E:\dot net SDK.exe" variable="test">
<CFSET tickEnd = GetTickCount()>
<CFSET loopTime = tickEnd - tickBegin>
<cfoutput>#len(test)#, #loopTime#</cfoutput>
<br>
<cfobject type="java" class="FileLoader" name="myObj" action="Create">
<CFSET tickBegin = GetTickCount()>
<cfset myObj.init("dot net sdk.exe")>
<CFSET tickEnd = GetTickCount()>
<CFSET loopTime = tickEnd - tickBegin>
<cfset test2 = myObj.getFileLength()>
<cfoutput>#test2#, #loopTime#</cfoutput>
