I think you missed the context of what I was responding to, which was about whether databases could even have micro-benchmarks.
You also missed the word "Obsolete" splattered all over the website you sent me, and the text that TPC-B was "Obsolete as of 6/6/95".
I don't think I have. I was only responding to the factually incorrect statement of yours that pgbench is a microbenchmark.
> which was about whether databases could even have micro-benchmarks.
No, this was an argument of yours that you pulled out out of nowhere. The topic very specifically was about the pgbench and not whether or not databases can have micro-benchmarks. Obvious answer is, yes, they can as any other software out there.
I think that you kinda tried to imply that pgbench was one of such micro-benchmarks in disguise and which is why I c/p the description which proves that it is not.
> You also missed the word "Obsolete"
I did not since that was not the topic being discussed at all. And in a technical sense, it doesn't matter at all. pgbench still runs so it is very much "not obsolete".
I didn't pull this argument out of nowhere, please read the direct comment I was replying to. Your position is also completely untenable: this benchmark was obsoleted by its creators 29 years ago, who very clearly say it is obsolete, and you're arguing that it isn't because it "still runs."
I'm guessing that this discussion would be more productive if you would please say who you are and the company you work for. I'm Brendan Gregg, I work for Intel, and I'm well known in the performance space. Who are you?

Wow, just wow. How ridiculous this is?

My only position in the whole thread was "1% of overhead cannot be universally claimed" and I still stand by it 100%. pgbench experiment from Linux kernel folks was just one of the counter-examples that can be found in the wild that goes against your claim. And which you first disputed by saying that it is a micro-benchmark (meaning that you have no idea what it is) and now you're disputing it by saying it's obsolete (yes, but still very relevant in database development, used in the Linux kernel and not the slightest technical reasoning after all).
Personally, I couldn't care less about this but if names is what you're after, you're not disagreeing with me but with the methodology and results presented by Mel Gorman, Linux kernel developer.
