> {{BufferedReader}} is a synchronized method class which means that every call to {{read}} requires synchronization.
> Usually it's not an issue, but for {{commons-csv}}, it adds a lot of overhead because it reads each  byte one at a time.  So even though it's buffered, it has to go through a synchronization processes for each byte read.
> Change {{ExtendedBufferedReader}} to implement its own internal buffer.
