AI优化版sqlite和原版简单对比测试

有人利用AI优化sqlite原版源代码得到了更快的结果。https://sqlite.org/forum/forumpost/1f1b969bf4把他公布的代码取下来测试。https://github.com/ksenxx/sqlite-optimized/编译root6ae32a5ffcde:/par/sqlite-optimized-master# ./configure No installed jimsh or tclsh, building local bootstrap jimsh0 Configuring SQLite version 3.54.0 Host System...x86_64-pc-linux-gnu Build System...x86_64-pc-linux-gnu Source dir /par/sqlite-optimized-master Build dir /par/sqlite-optimized-master C compiler... cc C compiler... c Build C compiler...cc Checking for stdlib.h...ok Checking for sys/types.h...ok Checking if -D_FILE_OFFSET_BITS64 is needed...no SQLITE_DEBUG build? no Looking for install ... /usr/bin/install Checking for int8_t...ok Checking for int16_t...ok Checking for int32_t...ok Checking for int64_t...ok Checking for intptr_t...ok Checking for uint8_t...ok Checking for uint16_t...ok Checking for uint32_t...ok Checking for uint64_t...ok Checking for uintptr_t...ok Checking for gmtime_r...ok Checking for isnan...ok Checking for localtime_r...ok Checking for localtime_s...not found Checking for usleep...ok Checking for utime...ok Checking for pread...ok Checking for pread64...ok Checking for pwrite...ok Checking for pwrite64...ok Checking libs for fdatasync...none needed Checking libs for nanosleep...none needed Checking for sys/types.h...(cached) ok Checking for sys/stat.h...ok Checking for dlfcn.h...ok Checking for unistd.h...ok Checking for stdlib.h...ok Checking for malloc.h...ok Checking for memory.h...ok Checking for string.h...ok Checking for strings.h...ok Checking for inttypes.h...ok Checking for zlib.h...ok Checking libs for deflate...-lz Use amalgamation for builds? yes Use gcov? no test-runner flags: no Use #line macros in the amalgamation: no Checking whether the C compiler accepts -fsanitizeaddress...yes Checking whether the C compiler accepts -fsanitizebounds-strict...yes Checking for a suitable tcl...
