Some of these currently take a very long time to parse. I set those to only run one loop in the run-benchmark make target. 4096 may be a fairly small buffer, and definitely make the problem worse than it otherwise would've been, but similar sizes exist in real code: * 2048 bytes in cpython Modules/pyexpat.c * 4096 bytes in skia SkXMLParser.cpp * BUFSIZ bytes (8192 on my machine) in expat/examples The files, too, are inspired by real-life examples: Android stores depth and gain maps as base64-encoded JPEGs inside the XMP data of other JPEGs. Sometimes as a text element, sometimes as an attribute value. I've seen attribute values slightly over 5 MiB in size.

This directory contains some really large test files, mostly used to
|
|
benchmark various aspects of Expat's performance.
|
|
|
|
(As files are added, they should be described here, including what
|
|
benchmark program they're intended to be used with and what that
|
|
resulting measurements tell us.)
