From 2650b6f9147c0d855c2763610b8a4bff18f5b5e0 Mon Sep 17 00:00:00 2001 From: Sam James Date: Tue, 8 Nov 2022 07:14:38 +0000 Subject: [PATCH] maintainer-scripts/gcc_release: compress xz in parallel 1. This should speed up decompression for folks, as parallel xz creates a different archive which can be decompressed in parallel. Note that this different method is enabled by default in a new xz release coming shortly anyway (>= 5.3.3_alpha1). I build GCC regularly from the weekly snapshots and so the decompression time adds up. 2. It should speed up compression on the webserver a bit. Note that -T0 won't be the default in the new xz release, only the parallel compression mode (which enables parallel decompression). -T0 detects the number of cores available. So, if a different number of threads is preferred, it's fine to set e.g. -T2, etc. Signed-off-by: Sam James * gcc_release (XZ): Add -T0. --- maintainer-scripts/gcc_release | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/maintainer-scripts/gcc_release b/maintainer-scripts/gcc_release index 2456908d716..962b8efe99a 100755 --- a/maintainer-scripts/gcc_release +++ b/maintainer-scripts/gcc_release @@ -609,7 +609,7 @@ FILE_LIST="" # Programs we use.
