> We run a benchmarking test, and indexing a dataset of vectors of 1536 dims was slightly faster than indexing of 1024 dims. This gives us enough confidence to extend max dims to 2048 (at least when vectorization is enabled). I found this very strange at first :) But then I read more closely, and I think what you meant is indexing 1024 dims without Panama (SIMD vector instructions) is slower than indexing 1536 dims with Panama enabled? Which is really quite impressive. Do we know what gains we see at search time going from 1024 -> 1536? -- This is an automated message from the Apache Git Service.
