From the performance in cases where the length of the data to be encrypted. When the data length is more result in reduced compression ratio due to duplication of characters or contains invalid characters.
Results of operations in the event of a data length to be encoded differently. Once the data has resulted in a greater length compression rate lower. Because of the repetition of the characters or the characters unique.
The net in case the length of data was used to encode different When the data length data compression ratio decreased, resulting in a more Due to the overlap of the character or the character again
