What order should I use GzipOutputStream and BufferedOutputStream

Can anyone recommend whether I should do something like:

os = new GzipOutputStream(new BufferedOutputStream(...));

or

os = new BufferedOutputStream(new GzipOutputStream(...));

Which is more efficient? Should I use BufferedOutputStream at all?

java gzipoutputstream

Read the javadoc, and you will discover that BIS is used to buffer bytes read from some original source. Once you get the raw bytes you want to compress them so you wrap BIS with a GIS. It makes no sense to buffer the output from a GZIP, because one needs to think what about buffering GZIP, who is going to do that ?

new GzipInputStream( new BufferedInputStream ( new FileInputXXX
