Go performance test: No optimizations were made

This is a creation in Article, where the information may have evolved or changed.

The Srs.go TCP module for go and the Web server Martini did a preliminary performance test without any optimizations.

When the go direct TCP packet is sent, the performance is worse than the C + + direct packet. Python directly sends TCP packets with good performance.

In high traffic, go behaves much better than Python and is better than openresty.

Go is less efficient than C + +, and it may be better to deploy and multi-CPU, and the server code is not as hard to write.

Go is now looking to achieve the goal of efficient python. It should be considered in the backend, especially some APIs.

Dependency Packages

Openresty's dependencies are a whole bunch of packages that are not easy to deploy:

[Winlin@dev6 web]$ ldd objs/_release/nginx/sbin/nginxlinux-vdso.so.1 = (0x00007fff6efcf000) libpthread.so.0 = /lib64/libpthread.so.0 (0x0000003218400000) libcrypt.so.1 =/lib64/libcrypt.so.1 (0x0000003221c00000) libm.so.6 = >/lib64/libm.so.6 (0x0000003217c00000) libpcre.so.0 =/lib64/libpcre.so.0 (0x000000314ca00000) libssl.so.10 = >/usr/lib64/libssl.so.10 (0x0000003ef7600000) libcrypto.so.10 =/usr/lib64/libcrypto.so.10 ( 0x0000003ef7200000) libdl.so.2 =/lib64/libdl.so.2 (0x0000003218000000) libz.so.1 =/lib64/libz.so.1 ( 0x00000032ed000000) libgcc_s.so.1 =/lib64/libgcc_s.so.1 (0x000000328f200000) libc.so.6 =/lib64/libc.so.6 ( 0x0000003217800000)/lib64/ld-linux-x86-64.so.2 (0x0000003217000000) libfreebl3.so =/lib64/libfreebl3.so ( 0x0000003221800000) libgssapi_krb5.so.2 =/lib64/libgssapi_krb5.so.2 (0x0000003223c00000) libkrb5.so.3 =/ Lib64/libkrb5.so.3 (0x0000003224c00000) libcom_err.so.2 =/lib64/libcom_err.so.2 (0x0000003222000000) libk5cRypto.so.3 =/lib64/libk5crypto.so.3 (0x0000003222800000) libkrb5support.so.0 =/lib64/libkrb5support.so.0 ( 0x0000003224800000) libkeyutils.so.1 =/lib64/libkeyutils.so.1 (0x0000003222c00000) libresolv.so.2 =/lib64/ Libresolv.so.2 (0x0000003219400000) libselinux.so.1 =/lib64/libselinux.so.1 (0x0000003219000000)

Gomartini does not have an extra dependency package, and Python is packaged like this:

[Winlin@dev6 web]$ ldd Objs/go.martini linux-vdso.so.1 =  (0x00007fffd25ff000) libpthread.so.0 =/lib64/ libpthread.so.0 (0x0000003218400000) libc.so.6 =/lib64/libc.so.6 (0x0000003217800000)/lib64/ Ld-linux-x86-64.so.2 (0x0000003217000000)

Compare the size of the package:

[Winlin@dev6 web]$ ls-lh objs/go.martini-rwxrwxr-x 1 winlin winlin 6.4M Nov  3 14:35 objs/go.martini[winlin@dev6 web] $ ls-lh objs/_release/nginx/sbin/nginx-rwxrwxr-x 1 winlin winlin 14M Nov  3 12:05 Objs/_release/nginx/sbin/nginx

Go is doing well in this area.
