Agree with everything Felix and Bjorn have said, just want to ask: How many rows are there where deletes=1? If it's not many then an index on deletes will help MySQL reduce the number of rows it needs to look at (and join on) greatly.
If not and you're not getting the speed you want from Bjorn and Felix's suggestions, another thing to look at is that query profiler tool I mentioned. It will give a good idea whether your query is using various MySQL buffers efficiently or not, which will allow people to advise on any config changes that might help you.
