Nginx is the fastest to serve small static file on my VPS. No significant difference in serving larging file.

Speedup Mysql and Webserver with Intel Compiler and tcmalloc

February 20th, 2009
2 comments

After reading some recent benchmark reguarding tcmalloc  performance on mysql. I decide to rebuild my whole webhosting stack with it.

ICC is intel’s c++ compiler, which has faster performance is also memtioned on mysql website.

Most distros should already has google performance tools prepackaged. Installation of ICC is slightly more complicated, you can download it directly from intel’s website which is free download for non-commercial use. Archlinux and Gentoo both have packaged installer. On ubuntu/debian system you probably also need build-essential and apt-build to rebuilt packages. On archlinux you will need base-devel and abs.

For most packages, the following bash script can be used before configuration/make step.  Don’t ommit the dot on first line and change the path of iccvars.sh to your installation directory.

 . /opt/intel/Compiler/11.0/081/bin/iccvars.sh intel64
CC=icc
CFLAGS="-xHOST -O3 -no-prec-div "
LD=xild
AR=xiar
CXX=icpc
CXXFLAGS="-xHOST -O3 -no-prec-div "
LDFLAGS=-ltcmalloc_minimal
export CC CFLAGS LD AR CXX CXXFLAGS LDFLAGS

These setting seems safe for all packages. Here is a summary of package specific cflags setting.

  Mysql Cherokee Nginx Varnish PHP Memcached
-static No No No No N/A No
-ipo No No Yes No N/A Yes
LDFLAGS=-ltcmalloc_minimal Yes Yes Yes Yes Yes Yes
configure option –disable-shared –with-mysqld-libs=-ltcmalloc_minimal None None –disable-jemalloc Failed with ICC None

This might disappoint you. But the rebuilt software stacks show no improvement whatsoever in my benchmark.

Correct way to password protect Cherokee webserver

February 8th, 2009
1 comment

I have played Cherokee server on my personal blog a couple of days. I used it for some private file. Some directories need to be password protected. Initially I set it up in this way.

Incorrect password protection for Cherokee webserver

Incorrect password protection for Cherokee webserver

Then I tested against some static files, it obviously worked. However a couple days later, I realize the php script inside this directory was not protected at all including index.php. A rather easy fix, I added the same auth method to php handler as well. However as I add more stuff into my private directory, some of them require individual handler to work correct, so I added same http authentication method to all of them. It is really a pain to maintain such a long auth list, suddenly I realized I must have done this in a wrong way.

After digging into the cherokee document and cookbook, I find this simple solution to protect a whole directory.

  1. Add a directory rule which match the directory you want to protect.
  2. Set the handler to None in Handler tab
  3. Set authentication method in Security tab.
  4. Move this rule to the top and uncheck final.

That’s it.
