Compression with 11g expdp

In 9i, I used to export and then gzip the dump file, but with 10g, oracle expdp could compress the METADATA, but with 11g, I can compress everything. Yes, expdp of 11g has more compression options than erstwhile 10g

$ expdp help=y

:

COMPRESSION

Reduce the size of a dump file.

Valid keyword values are: ALL, DATA_ONLY, [METADATA_ONLY] and NONE.

 I did a comparison between  11G’s expdp, 11G’s expdp + compression=ALL, 11G’s expdp + GZIP and exp + pipe node + GZIP on a database of size 2GB(approx) and below table describes the size of the dump file.

Sno	Scenario	Size in MB
1	Expdp	2226
2	expdp + compression=ALL	522
3	expdp + gzip	425
4	exp + pipe node + gzip	424

 There wasn’t much notable difference in the time taken. Whatever, I would  go for the 11g expdp with compression=all than erstwhile exp.
