Verify installation:
: Detects filesystem type (ext4, XFS, Btrfs, F2FS) and appends FS-specific options (e.g., discard=async for ext4 on SSDs). 3.4 CPU Frequency & Scheduler If your kernel has CONFIG_CPU_FREQ_GOV_PERFORMANCE and CONFIG_SCHED_MC / CONFIG_SCHED_SMT : lfs pro tweaker 7d
CFLAGS="-march=native -mtune=native -O3 -pipe -flto=auto -fuse-linker-plugin -fomit-frame-pointer" CXXFLAGS="$CFLAGS" MAKEFLAGS="-j$(nproc)" : Automatic detection of -march via gcc -march=native -Q --help=target and fallback to -march=x86-64-v3 for older compilers. 3.2 Kernel Sysctl Tuning The script generates a file under /etc/sysctl.d/ . Example for a database server: cp /usr/share/lfs-pro-tweaker/profiles/hpc-compute
