From 0ae9b9a14d54bd0aa68c1e8bda9dd8e6346f1d87 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Sat, 16 Mar 2024 18:23:44 -0600 Subject: [PATCH] io_uring/alloc_cache: shrink default max entries from 512 to 128 In practice, we just need to recycle a few elements for (by far) most use cases. Shrink the total size down from 512 to 128, which should be more than plenty.
