Average time to evaluate rule groups is higher when using streaming of chunks
When using streaming of chunks as implemented in https://github.com/cortexproject/cortex/pull/3889, average time to evaluate rule groups goes up.
Is it because of the chunks decoding done in the ruler (instead of spreading it across all ingesters)? Do you have any ruler trace to investigate it further?

I assume that is the case, but haven't investigated it further yet. What is worrying is that rule evaluation has doubled in average, but it could also be specific to rules.

Answering my own question: no it was not fixed. That part improves, but mergeIterator seems to be so much slower that it defeats the improvement.
