[QScintilla] Need to get optimal size of buffer when appen o QScintilla object

[Roshni Lalwani]

I want to know what is optimal size of bufferSize  in following code

class myView : public QScintilla {


void myView::readFile(QString ofilename) {

if (FILE* fp = fopen(ofilename.toLatin1().constData() "r")) {
QTextStream ts(fp, QIODevice::ReadOnly);
        int bufferSize = 8192;
        do {
          QString s =  ts.read(bufferSize);
  append(s);
        } while(!ts.atEnd());
setModified(FALSE);
UFile::close(fp);
d_filename = ofilename;
emit fileNameChanged(ofilename);
      }

}
}
so that we do not see any  run time issues
