Slow SWA transfer

Hello,
my web service based on the example http://wso2.org/library/1675 is kind of
slow. My test binary has a size of 50 MB. scp needs only 2 seconds for the whole
file - the web service needs approximately 9 seconds.

Thanks
Martin

250 MB are transferred in 43 seconds.
I found a post on the mailing list from 2006
http://mail-archives.apache.org/mod_mbox/ws-axis-c-dev/200605.mbox/%3Cd84ebd2d0605130053n4446bbccp109559ec6e66d265@mail.gmail.com%3E

Is this problem based on the chunk size?

org.apache.commons.httpclient.ChunkedOutputStream:
------------------------ 8< ------------------------
    /**
     * Wraps a stream and chunks the output. The default buffer size of 2048 was
chosen because
     * the chunk overhead is less than 0.5%
     * @param stream
     * @throws IOException
     */
    public ChunkedOutputStream(OutputStream stream) throws IOException {
        this(stream, 2048);
    }
------------------------ 8< ------------------------

regards
Martin
