Redis Sort by foreign key is slow

HI,i create 100 set in redis,every set have 1000 members.At the same time,I have 10000 hashes,every hash have 50 fields. My command like this:sort set0 by h*->field3 desc. 476.15 requests per second

This reasonable. Note that the response will contain 1000 items. Such a big response will affect performance. Additionally the sort operation's complexity is O(N*log(N)) and the extra lookup per hash also reduces performance. I'm closing.
