alternative operating-systems[2021/04,2023/10] Alternatives away from RPIOS which has become bloated and infected with Systemd Virus. FreeBSDFreeBSD 13 has some device-drivers, but lacks wireless. FreeBSD has elevated RPI to 'Tier 1' status (meaning complete support). NetBSDNetBSD 10 has almost all RPI device-drivers. Alpine LinuxAlpine Linux is a very minimal Linux system (what RPIs need). Void LinuxVoid Linux offers installers specific to various RPI models. Haiku (BeOS clone)Haiku is worth watching, its developers have begun porting to RPI. (More about BeOS/Haiku.) |
benchmarksSpeed of compiling GNU Emacs[2021/05] Not equal comparisons. Variously compiled Emacs versions 24..27 (Mac Mini G4 limited to Emacs-24). Emacs usually was compiled in temp RAM on systems having sufficient ample memory. ~40 sec PC Intel Goldmont+ J5005 SoC, 2.8Ghz, 4 cores (make -j4) ~80 sec PC Intel Core 2 Duo, 2.2Ghz, 2 cores (make -j2) ~105 sec unfair PC Intel Goldmont+ J5005 SoC, 2.8Ghz, 4 cores (make -j1) ~115 sec PC AMD64X2 2.2Ghz, 2 cores (make -j2) ~194 sec Raspberry Pi 3B+, 1.4Ghz ARMv8, 4 cores (make -j4, running in 32-bit ARMv7 mode, compiled on temp RAM) ~213 sec Raspberry Pi 3B+, 1.4Ghz ARMv8, 4 cores (make -j4, running in 32-bit ARMv7 mode, compiled on SDCARD) ~390 sec Mac Mini PowerPC G4 7450 1.33Ghz (make -j1, compiled on mechanical disk-drive) ~423 sec unfair Raspberry Pi 3B+, 1.4Ghz ARMv8, 4 cores (make -j1, running in 32-bit ARMv7 mode, compiled on temp RAM) ~470 sec unfair Mac Mini PowerPC G4 7450 1.33Ghz (make -j1, compiled on USB1 memory) 2613 sec Raspberry Pi Zero W, 1Ghz 32-bit ARMv6, 1 core (make -j1) |
