Performance
pglue implements automatic query pipelining which makes it especially performant with many queries concurrently executed on a single connection.
Benchmarks
Performance is generally on par with postgres.js and up to 5x faster than deno-postgres. Keep in mind that database driver benchmarks are largely dependent on the database performance itself and does not necessarily represent accurate real-world performance.
Tested on a 4 core 2800 MHz x86_64-pc-linux-gnu QEMU VM with Deno 2.1.4 and local PostgreSQL 17.1 installation connected via TCP on localhost:
Test query: select * from pg_type
CPU | Common KVM Processor v2.0
Runtime | Deno 2.1.4 (x86_64-unknown-linux-gnu)
