: We do optimize the index before updates but we get tehse performance issues : even when we pull an empty snapshot. Thus even when our update is tiny, the : performance issues still happen.
FWIW: this behavior doesn't make a lot of sense -- optimizing just before you are about to make updates/additions ot your data, is a complete waste. the main value in optimizing your index is that you have one segment, as soon as you add a docment that changes. the other thing to keep in mind is that an optimized index is a completley new segment as a new file with a new name, so there is going to be added overhead on the slave machines as the OS purges the old index files and replaces them with the new optimized index files -- more overhead then if you had just done your additions w/o optimizing first. -Hoss
