Subject: C trigger significantly slower than PL/pgSQL?
Date: Wed, 12 Apr 2023 09:35:10 +0200 (CEST)
Message-ID: <[email protected]> (raw)
Hello all,
I have a functionally identical trigger function in PL/pgSQL and C. Now, that the C version is about 3x _slower_ (~1500 vs. ~4500 TPS in pgbench) than PL/pgSQL comes somewhat unexpected.
It can very well be, that I made a mistake on the C side, but before everything else, I'd like to ask if this may be expected behavior. Is it plausible that PL/pgSQL is so much faster than C when used in a trigger function?
best regards
Ernst-Georg
