Bonjour,

Je fais un envoi de fichier sur un serveur FTP comme ceci :

ftp.enterLocalPassiveMode();
			 	InputStream inputStream   = new FileInputStream(rep);
			 	OutputStream outputStream = ftp.storeFileStream(rep.getName());
	            byte[] bytesIn = new byte[1024];
	            int read = 0;
 
	            while ((read = inputStream.read(bytesIn)) != -1) {
	            	long d = System.currentTimeMillis();
	                outputStream.write(bytesIn, 0, read);
	                long f = System.currentTimeMillis();
	                System.out.println("Time : " + f + " - " + d + " = " + (f - d));
	            }
 
	            outputStream.flush();
	            inputStream.close();
	            outputStream.close();
 
	            boolean completed = ftp.completePendingCommand();
	            if (completed) 
	            {
	                System.out.println("The file is uploaded successfully.");
	            }
Mon "Benchmark" me sort des choses étonnantes ; J'ai une série d'envois qui se font en moins d'une milliseconde et d'un coup (et ceci à intervalle pseudo-régulier) j'ai un temps d'envoi plus long (> 100 ms).

La preuve ici :
