Release 862 - The Need for Speed

Speed is one of the most important usability factors for a search engine.

In this version of Trexy you can now search where the trails intersect. But computing trail intersection points is expensive and in some pathological cases we were seeing a 24sec response time - which is totally unacceptable.

I felt a sense of deja vu as I refactored the core search engine to make it faster and I'm really happy to report my efforts paid off.

The average response time is now less than 200ms! ;-)

Keep an eye on the base of the Trexy results page. You can see the response time there - if it ever goes above 400ms please email:
