Having more size pools will allow us to allocate larger objects through Variable Width Allocation. I have attached some benchmark results below. Discourse: On Discourse, we don't see much change in response times. We do see a small reduction in RSS. Branch RSS: 377.8 MB Master RSS: 396.3 MB railsbench: On railsbench, we don't see a big change in RPS or p99 performance. We see a small increase in RSS. Branch RPS: 815.38 Master RPS: 811.73 Branch p99: 1.69 ms Master p99: 1.68 ms Branch RSS: 90.6 MB Master RSS: 89.4 MB liquid: We don't see a significant change in liquid performance. Branch parse & render: 29.041 I/s Master parse & render: 29.211 I/s
