開啟JIT情況下是不開啟JIT情況下的接近9.15倍，多次測(cè)試這個(gè)值穩(wěn)定在8倍到10倍之間。
MPF表現(xiàn)如何？
為了接近我們的業(yè)務(wù)，所以在mpf框架下進(jìn)行測(cè)試

發(fā)現(xiàn)計(jì)算少情況下php8JIT是php7性能的13倍，而且計(jì)算越多優(yōu)化越明顯，計(jì)算多情況下php8JIT是php7性能的25.7倍。
但是有一個(gè)問題我覺得很神奇php8無JIT計(jì)算少的情況居然也優(yōu)化了很多，我以為是測(cè)試方向的問題，但是經(jīng)過多次論證，這個(gè)數(shù)據(jù)是準(zhǔn)確的，有時(shí)間想找一下這里的優(yōu)化點(diǎn)是什么。
編譯過程
吐槽：php手動(dòng)編譯越來越麻煩了，編譯了2個(gè)小時(shí)才編譯完，踩了N個(gè)坑，為了讓大家多寫幾個(gè)需求，把坑分享出來
環(huán)境
aliyun centos 6.9，咱們公司一般都是這個(gè)版本。
php源碼編譯
wget https://downloads.php.net/~carusogabriel/php-8.0.0alpha2.tar.gz tar -zxf php-8.0.0alpha2.tar.gzcd php-8.0.0alpha2 ./configure --prefix=/yourdir/php8 --with-config-file-path=/yourdir/php8/etc --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --enable-fpm --enable-static --enable-sockets --with-zip --enable-calendar --enable-bcmath --enable-mbstring --with-zlib --with-iconv=/usr/local/libiconv --enable-gd --enable-mbstring --with-freetype --with-mysql-sock=/tmp/mysql.sock --disable-ipv6 --enable-debug --with-openssl --enable-opcache復(fù)制代碼
這里一般都是makefile生成失敗的，后面有生成失敗的例子，生成成功后
make -j 8 make install cp php.ini-production /yourdir/php8/etc/php.ini
配置php.ini
記住一定要把opcache.ini舊的配置也寫上，JIT說到底還是對(duì)Opcache的優(yōu)化。
zend_extension=opcache.so opcache.enable=1 ; 命令行測(cè)試的話這里一定要打開 opcache.enable_cli=1 opcache.memory_consumption=512 opcache.interned_strings_buffer=8 opcache.max_accelerated_files=10000 opcache.validate_timestamps=1 opcache.revalidate_freq=300 opcache.fast_shutdown=1 opcache.enable_file_override = 1 opcache.blacklist_filename = /etc/php.d/opcache.blacklist ; 這里就是新的jit的配置 opcache.jit=1205 opcache.jit_buffer_size=64M
configure失敗解決方法
這里解決./configure 失敗的一些問題
問題一
No package 'sqlite3' found
解決辦法
wget https://www.sqlite.org/2020/sqlite-autoconf-3320300.tar.gz tar -zxf sqlite-autoconf-3320300.tar.gzcd sqlite-autoconf-3320300 ./configure --prefix=/usr/local/lib/sqlite-3.32.0 make CFLAGS="-g -O2 -DSQLITE_ENABLE_COLUMN_METADATA"make installexport PKG_CONFIG_PATH="$PKG_CONFIG_PATH:/usr/local/lib/sqlite-3.32.0/lib/pkgconfig"復(fù)制代碼
注意
直接這樣是不行的，yum倉庫里的版本太低。
yum install sqlite-devel
問題二
configure: error: Please reinstall the iconv library.
解決辦法
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz tar -zxf libiconv-1.14.tar.gzcd libiconv-1.14 ./configure make make install
問題三
No package 'oniguruma' found
同樣yum也是不行的，版本太低。
yum install oniguruma-devel
解決辦法
wget https://github.com/kkos/oniguruma/archive/v6.9.5_rev1.tar.gz tar -zxf v6.9.5_rev1.tar.gzcd oniguruma-6.9.5_rev1/ autoreconf -vfi ./configure --prefix=/usr/local/lib/oniguruma-6.9.5 make make installexport PKG_CONFIG_PATH="$PKG_CONFIG_PATH:/usr/local/lib/oniguruma-6.9.5/lib/pkgconfig"
問題四
No package 'libzip' found
解決辦法
wget https://libzip.org/download/libzip-1.7.2.tar.gz tar -zxf libzip-1.7.2.tar.gzcd libzip-1.7.2 cmake3 -DCMAKE_INSTALL_PREFIX=/usr/local/lib/libzip-1.7.2 make make installexport PKG_CONFIG_PATH="$PKG_CONFIG_PATH:/usr/local/lib/libzip-1.7.2/lib/pkgconfig"復(fù)制代碼
