六、httperf工具，来自hp的工具，不过已经n年没有更新了。
wget ftp://ftp.hpl.hp.com/pub/httperf/httperf-0.9.0.tar.gz
$ mkdir build
$ cd build
$ SRCDIR/configure
$ make
$ make install
工具使用方法：
/usr/local/bin/httperf –help Usage: httperf [-hdvV] [--add-header S] [--burst-length N] [--client N/N] [--close-with-reset] [--debug N] [--failure-status N] [--help] [--hog] [--http-version S] [--max-connections N] [--max-piped-calls N] [--method S] [--no-host-hdr] [--num-calls N] [--num-conns N] [–period [d|u|e]T1[,T2]] [--port N] [–print-reply [header|body]] [–print-request [header|body]] [--rate X] [--recv-buffer N] [--retry-on-failure] [--send-buffer N] [--server S] [--server-name S] [--session-cookies] [--ssl] [--ssl-ciphers L] [--ssl-no-reuse] [--think-timeout X] [--timeout X] [--uri S] [--verbose] [--version] [--wlog y|n,file] [--wsess N,N,X] [--wsesslog N,X,file] [--wset N,X] |
如：
/usr/local/bin/httperf –server www.2hei.net \
–port 443 –uri /mt/index.html \
–rate 15 –num-conn 1000 \
–num-call 1 –timeout 5
发现会有如下错误：
httperf: warning: open file limit > FD_SETSIZE; limiting max. # of open files to FD_SETSIZE
以下是解决办法：
# Edit /etc/security/limits.conf and add the line * hard nofile 65535 (or instead of * you can put the username of the user for whom you want to change the limit)
# Edit /usr/include/bits/typesizes.h and change #define __FD_SET_SIZE 1024 to #define __FD_SET_SIZE 65535 (in /usr/include/sys/select.h FD_SETSIZE is defined as __FD_SETSIZE)
重新编译即可。
实例测试如下：
