Description

This problem is exhibited in FreeMind
(http://freemind.sourceforge.net/wiki/index.php/Main_Page) which I think uses
Batik 1.1.4. The FreeMind developers say this is a Batik problem.

When exporting a PDF file from FreeMind to PDF across a LAN, it can take 20-30
minutes to create a 1MB PDF file. When exporting the same FreeMind file to
PDF on a local disk, export is almost instantaneous.

Filemon from Sysinternals (http://www.sysinternals.com) reports that the PDF
file is being created in 1 byte increments. For a 1MB file, that equates to
over 1 million write requests. Across a LAN, this many packets over such a
short period of time will cause a large number of collisions, requiring many
retransmits. The problem is worse if there is moderate network traffic on the
LAN from other hosts.
