This directory contains a few performance tests for loading xddl, decoding, and decoding to xml.
These tests can be run using make perf after building the xenon tree.
Results
Compared to release 2.0.0:
Loading specs: 1.4 times faster
Decoding messages to xml : 1.6 times faster
Results vary based on architecture. The above statistics come from my desktop rig. On my MacBook Air, the xml decoding shows a 2X improvement. These variances may be due to clang and gcc differences, or different cache sizes. Either way, things are getting faster.
Using ict::osstream
Until now, xenon has used std::ostringstream for building strings. Although convenient, this method is notoriously slow. I finally addressed this by implementing ict::osstream. This is a simple reusable type that provides basic ostream operations for strings and numbers, but nothing else.
Internal Updates
xenon::recref
Created a new type called xenon::recref. This replaces the previous usage of ict::url. ict::url was a bit too ambitious of a name. recref is represents a path to a record in the xddl tree. The API has been updated to use it, for example:
Going forward, the plan is to improve addressing of records to more closely match the method used on the http://intrig.com website. For example a recref that is currently defined like this:
