but I need a quick demo to see the memory profiling or CPU profiling. I
hope a blog or a video which is better for me. Thanks.<br/><br/><br/><html>

<div>Hi jacktby,
<br/>
<br/>PostgreSQL is literally a large and complicated program in C. Thus it
<br/>can be profiled as such. E.g. you can use `perf` and build flamegraphs
<br/>using `perf record`. Often pgbench is an adequate tool to compare
<br/>before and after results.There are many other tools available
<br/>depending on what exactly you want to profile - CPU, lock contention,
<br/>disk I/O, etc. People write books (plural) on the subject. Personally
<br/>I would recommend "System Performance, Enterprise and the Cloud, 2nd
<br/>Edition" and "BPF Performance Tools" by Brendan Gregg.
<br/>
