Jim Apple has uploaded a new patch set (#4). Change subject: Use AVX2 operations to speedup Bloom filter insert by 10-50%. ......................................................................
Use AVX2 operations to speedup Bloom filter insert by 10-50%. Impala supports machines that do not have AVX2 instructions, so the fast insert path is only conditionally enabled. This condition check does not hurt Insert()'s speed. I also needed to make a minor change to the order of libraries in LD_LIBRARY_PATH when using the toolchain.
