> GzipCompressorOutputStream should forward write(byte[] buf) and write(byte[]

> 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
> Fix For: 1.1
>
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> 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.
