GzipCompressorOutputStream should forward write(byte[] buf) and write(byte[]
buf, int off, int len) to underlying stream
------------------------------------------------------------------------------------------------------------------------
Key: COMPRESS-83
URL: https://issues.apache.org/jira/browse/COMPRESS-83
Project: Commons Compress
Issue Type: Improvement
Affects Versions: 1.0
Environment: Linux
Reporter: Aleksey Shipilev
Current version of GzipCompressorOutputStream decorates only write(int b)
method for underlying java.zip.util.GZipOutputStream.
In common scenario of:
OutputStream os = ...;
GzipCompressorOutputStream gcos = new GzipCompressorOutputStream(os);
[do extensive write(byte[] buf]
this results in very slow _unbuffered_ write. This is particularly evident if
the code changes to:
OutputStream os = ...;
GZIPOutputStream gos = new GZIPOutputStream(os);
[do extensive write(byte[] buf]
...which is blazingly faster.
In my environment, packing 100 Mb stream with Commons wrapper takes about 120
seconds, while using java.util.zip directly takes less than 1 second.
This performance hit is way too bad for simple wrapper.
