From ced57f7888c9244f3e07e4b08462aeb64acd8c66 Mon Sep 17 00:00:00 2001 From: Jörg Thalheim Date: Fri, 16 Nov 2018 00:39:27 +0000 Subject: nixos/nix-daemon: default to build with all cores available These days build systems are more robust w.r.t. to concurrency. Most users will have at least two cores in their machines. Therefore I suggest to increase the number of cores used for building. fixes #50376 --- nixos/modules/services/misc/nix-daemon.nix | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'nixos') diff --git a/nixos/modules/services/misc/nix-daemon.nix b/nixos/modules/services/misc/nix-daemon.nix index 973575570612..9a8116a03e88 100644 --- a/nixos/modules/services/misc/nix-daemon.nix +++ b/nixos/modules/services/misc/nix-daemon.nix @@ -117,11 +117,11 @@ in buildCores = mkOption { type = types.int; - default = 1; + default = 0; example = 64; description = '' This option defines the maximum number of concurrent tasks during - one build.
