[Php-java-bridge-users] performance

[Marek L. <ma...@le...>]

Hello Jost,
I'm writing about performance of php/java bridge. I've noticed that 
creating objects take much more time comparing to Java. I understand 
that some decrease of speed is natural, however this should not be so 
visible. Look at below benchmarks:

- java
package example;

import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFCell;

class exampleclass {
	
	public void exampleclass () {
		
		HSSFWorkbook workbook = new HSSFWorkbook();
		HSSFSheet sheet = workbook.createSheet();
		HSSFRow row = sheet.createRow(0);
		HSSFCell cell = row.createCell((short) 0);
		
	}
	
}

from php: $spreadsheet = new java("example.exampleclass");

-----------------------------------------------------------------
time 0.0790050029755 sec

- php:
print "\n\nFrom PHP:\n";
$workbook = new java("org.apache.poi.hssf.usermodel.HSSFWorkbook");
$sheet = $workbook->createSheet();
$row = $sheet->createRow(0);
$cell = $row->createCell(0);

-----------------------------------------------------------------
time 0.458841085434 sec


Now, if you will create only php objects (without $spreadsheet = new 
java("example.exampleclass")) then is even slower - about 0.55 sec. Is 
this a normal behavior ?
