Indexes are generally considered to be the panacea when it comes to SQL performance tuning, and PostgreSQL supports different types of indexes catering to different use cases. The benefits come with a cost in terms of performance and resource consumption. Effectively, the memory available for pages of the table gets less.

This technique saves two instructions in the prologue and epilogue and makes one additional general-purpose register (%rbp) available." I'm sure this delivered large performance improvements and I wouldn't try arguing against it. And for leaf routines (which never establish a frame), this is a non-issue.

In reality, though, of course, nothing changed for our first workload — it continues to be I/O-bound; it just became invisible when we look at “IOWait”!
