Description

Processing huge LDIF file is likely to take an enormous amount of time. The parser works in a way that we frequently fetch a char from a StringBuffer, to remove it later. When you have a 1Mb file, that induces the copy of a 1Mb array every time we don't need the char we just read.

Typically, parsing a 1 237 chars file, the noRead() method is called 393 times, and it calls the System.arrayCopy() the same number of time.
