slow website respond xampp windows 8 [solved]

http://www.apachefriends.org/f/viewtopic.php?f=16&t=51152

when user click php links that not require database it respond faster. localhost web respond with delay about 300ms if i have database query page. it occur even with simple mysql query. after searching around i found that windows 8 not able to locate localhost correctly (127.0.0.1 or ::0). this is my solution:

1. edit my.cnf located in C:\xampp\mysql\bin directory
2. find bind-address and uncomment 127.0.0.1 or ::1 which your pc use to connect localhost

 # Change here for bind listening  
 # bind-address="127.0.0.1"   
  bind-address = ::1     # for ipv6  

mine using ::1 and i uncomment that line.
3. restart mysql service. use xampp control panel (xampp-control) located at C:\xampp

you will see improvement after restart mysql service.
cheers.

go to line 46
type :46 on vi
replace function_entry with static zend_function_entry

exit vi. type :wq


./install

and success: :)

 Build complete.

 #! /bin/sh   
 #  
 # unifi-pppoe          Script to run PPPOE/VLAN for Telekom Malaysia  
 #        UniFi Broadband Internet Service.  
 # chkconfig: 345 10 90  
 # description: UniFi service provides Internet and IPTV service  
 #       over VLANs. This script sets your system to   
 #       connect to the IP Network. It also sets up a   
 #       bridged device to connection to the set top box  
 #       via another NIC.   
 ### BEGIN INIT INFO  
 # Provides:  unifi-pppoe  
 # Required-Start: $local_fs   
 # Required-Stop: $local_fs  
 # Default-Start:  3 4 5  
 # Default-Stop:  0 1 2 6  
 # Short-Description: PPPoE/VLAN for UniFi  
 ### END INIT INFO  
 # Settings:  
 USER=user@unifi  
 PASS=unifipassword  
 WANIFACE=eth1  
 INETVLAN=500  
 IPTVIFACE=eth2  
 IPTVVLAN=600  
 # INSTRUCTIONS:  
 #  
 # (1) Install this script   
 #  
 # Copy it to /etc/init.d/unifi-pppoe. Make sure it is owned by  
 # root and set the permission for it to 700.  
 #  
 # don't forget to install the following packages:  
 #      yum install vconfig rp-pppoe ppp bridge-utils  [CentOS]  
 #      sudo apt-get install vlan pppoe ppp bridge-utils [Ubuntu]  
 #  
 # Set it to run on startup automatically using:  
 #  chkconfig unifi-pppoe on        [CentOS]  
 #  update-rc.d unifi-pppoe defaults    [Ubuntu]  
 #  
 # (2) Edit the settings above  
 # Set USER to your UniFi user-id, PASS to your internet password.  
 # WANIFACE is the interface from which you connect your PC to the  
 # BTU.   
 # If you are using a vlan-tagging switch (e.g. mikrotik RB250GS or  
 # equivalent), set INETVLAN to blank. If your PC is connected   
 # directly to the BTU, set it to 500.  
 # Added a patch from Stanley Seow/rizvanrp for IPTV Vlan. You would   
 # need to set IPTVIFACE to the ethernet that your set top box is   
 # connected to, and IPTVVLAN to 600. If you don't have IPTV (e.g.  
 # UniFi BIZ), leave both settings blank.  
 # Example connection:  
 #  
 # +---------+     +-------------------+  
 # |Fiber BTU|---------|eth0  Linux PC  |  
 # +---------+     |          |  
 #           |  eth1   eth2  |  
 #           +-------------------+  
 #  +------+        |    |  
 #  | IPTV |----------------+    +--------- (LAN PCs)  
 #  +------+  
 #  
 # (3) Test it using:  
 #  /etc/init.d/unifi-pppoe start  [to start]  
 #  /etc/init.d/unifi-pppoe stop   [to stop]  
 # Note: If you're planning to run this for more than a few minutes,   
 #    make sure you setup a firewall on your system. Also, you  
 #    may share the internet connection with other PCs via   
 #    another interface. You can accomplish both of these using  
 #    the excellent arno-iptables-firewall script. Install this  
 #    from the website (for CentOS) or "sudo apt-get install  
 #    arno-uptables-firewall" on ubuntu and follow the instructions.
