Re: Query slow on Windows, fast on Ubuntu

Do you have the same setting for innodb_buffer_pool_size ?

It could very well be the performance is different between Linux and Windows, especially if your query is disk-bound. However, the difference is much larger than expected. Do the execution time change if you run it multiple times in a row?

How does it perform if you move all predicates from HAVING to WHERE and write "select straight_join ..." ?
