Technical Overview
Connection pooling is critical for high-throughput PostgreSQL workloads. PgBouncer (v1.21+) offers lightweight, transaction-level pooling with minimal overhead. This article dissects kernel-level tuning, pool sizing algorithms, and real-world benchmarks from Votion Cloud's bare-metal clusters.
Why PgBouncer?
- Reduces backend process fork/exec overhead
- Enables 10k+ concurrent client connections with 100-200 PostgreSQL backends
- Supports prepared statement caching across pooled connections

Kernel & Network Tuning
On bare-metal, we isolate CPU cores for PgBouncer and PostgreSQL using taskset and cgroups. Key sysctl parameters:
net.core.somaxconn = 65535
net.ipv4.tcp_max_syn_backlog = 65535
net.ipv4.tcp_tw_reuse = 1
net.ipv4.ip_local_port_range = 1024 65535
fs.file-max = 1000000
These prevent connection drops under burst traffic.
