The Yahoo! BlogSearch started off showing less than remarkable results in terms of performance (I leave the qalitative judgement to other critics). Over the last 11 days, the team at Yahoo! have realized that there may be an issue, and they have been working on it.
On Thursday afternoon (Oct 20, 2005), they obviously implemented a major change that caused performance to improve dramatically.

This improvement was due to some back-end changes in the search itself. How do I know this? All the improvement came in first-byte (server response time).

Would love to hear from the Yahoo team, and learn exactly what they did to bring about such a massive improvement.
