经过我的测试ICC在浮点运算，线程库和数学函数上的优势非常明显，原生SSE2指令集支持、Intel自己编写的线程库和数学函数库，性能没得说。
我用同一份运算PI值的代码在ICC和GCC下编译，提升比例达20%，实际在数据库中比较同一条超级复杂的聚合SQL，ICC提升达34%。
第一步：编译安装libunwind
wget http://download.savannah.gnu.org/releases/libunwind/libunwind-0.99.tar.gz
tar zxvf libunwind-0.99.tar.gz
CC=icc \
CXX=icpc \
LD=xild \
AR=xiar \
CFLAGS=”-O3 -no-prec-div -ip -xSSE2 -axSSE2″ \
CXXFLAGS=”${CFLAGS}” \
./configure && make && make install
第二布：编译安装tcmalloc
wget http://google-perftools.googlecode.com/files/google-perftools-1.6.tar.gz
tar zxvf google-perftools-1.6.tar.gz
CC=icc \
CXX=icpc \
LD=xild \
AR=xiar \
CFLAGS=”-O3 -no-prec-div -ip -xSSE2 -axSSE2″ \
CXXFLAGS=”${CFLAGS}” \
./configure –disable-debugalloc –enable-frame-pointers && make && make install
echo “/usr/local/lib” > /etc/ld.so.conf.d/usr_local_lib.conf
/sbin/ldconfig
第三部：编译安装Percona
CC=icc \
CXX=icpc \
LD=xild \
AR=xiar \
CFLAGS=”-O3 -unroll2 -ip -mp -restrict -fno-exceptions -fno-rtti -no-prec-div -fno-implicit-templates -static-intel -static-libgcc -xSSE2 -axSSE2″ \
CXXFLAGS=”${CFLAGS}” \
CPPFLAGS=” -I/usr/alibaba/icc/include ” \
LDFLAGS=” -L/usr/alibaba/icc/lib -lrt ” \
./configure –prefix=/usr/alibaba/install/percona-custom-5.1.53-12.4 \
–with-server-suffix=-alibaba-edition \
–with-mysqld-user=mysql \
–with-plugins=heap,innodb_plugin,myisam,partition \
–with-charset=utf8 \
–with-collation=utf8_general_ci \
–with-extra-charsets=gbk,utf8,ascii \
–with-big-tables \
–with-fast-mutexes \
–with-zlib-dir=bundled \
–with-readline \
–with-pthread \
–with-mysqld-ldflags=’-all-static -ltcmalloc’ \
–enable-assembler \
–enable-profiling \
–enable-local-infile \
–enable-thread-safe-client \
–without-embedded-server \
–with-client-ldflags=-all-static \
–with-mysqld-ldflags=-all-static \
–with-mysqld-ldflags=-ltcmalloc \
–without-query-cache \
–without-geometry \
–without-debug \
–without-ndb-binlog \
–without-ndb-debug
编译完成后make && make install
