After upgrade of sphinx from 0.9.8 to 0.9.9 we ran into serious problems with performance. Searchd works on EC2 large instance.

Queries started to work much slower and i often could see Z (zombie) searchd processes in top.

I expect this may be related to full-scan queries.

Did anyone experience anything like this?

We just tried to upgrade from to 0.9.9 and we also experienced slower responses... We went back to until 1.0.

I was not able to find cause of it and had to keep 0.9.8 until now. I doubt 1.0 helps, but know knows... – Andriy Bohdan Jan 9 '11 at 20:56
