Linux性能优化大师(基准测试)

1、cpu benchmark:nbench wget http://www.math.utah.edu/~mayer/linux/nbench-byte-2.2.3.tar.gz tar zxvf nbench-byte-2.2.3.tar.gz cd nbench-byte-2.2.3 yum install glibc-static -y make ./nbench 2、内存测试工具:stream wget http://www.nersc.gov/assets/Trinity--NERSC-8-RFP/Benchmarks/Jan9/stream.tar tar xvf stream.tar gcc -o stream stream.c ./stream

3、网络性能测试工具：netperf

git clone https://github.com/HewlettPackard/netperf.git

bash autogen.sh

yum install -y gcc gcc++ texinfo

./configure&&make&&make install

netserver

netperf -H 127.0.0.1 -t TCP_STREAM -l 30

netperf -H 127.0.0.1 -t UDP_STREAM -l 30

netperf -H 127.0.0.1 -t TCP_RR -l 30

netperf -H 127.0.0.1 -t UDP_RR -l 30

4、IO性能测试：iozone

rpm -ivh http://www.iozone.org/src/current/iozone-3-487.src.rpm

cd /root/rpmbuild/SOURCES/

tar xvf iozone3_487.tar

cd iozone3_487/src/current

make && make linux
