Which one of these problem is server side?

Post by hack3rcon » 2020/09/15 14:27:15

Hello,
I tested a CentOS web server speed and the ranking is as below:
web-test1.png
web-test1.png (25.88 KiB) Viewed 229 times
WEb-test3.png
WEb-test3.png (29.87 KiB) Viewed 229 times
I want to know which one of these problems is because of server configuration like Apache or... and not web programming?

Thank you.

First Byte Time, implies your server was too slow to respond with its first content (like a slow PHP script).

Compress Transfer, implies your apache and/or PHP script did not gzip/brotli/etc the HTML content at transfer time.

Cache static content, implies your apache does not send proper cache headers to enforce cache usage and a long timeout.

Anyway, here is a test on one of my ecommerce websites:

My server hosting a WordPress website. All of these poor performances is because of LAMP and not WordPress?
Can you offer some helps to improve it? Any change in configuration?

Apache handles compression through the module mod_deflate.
Change the config files to load the module by adding a line:

Code: Select all

LoadModule deflate_module modules/mod_deflate.so
Configure which file types to compress:

Code: Select all

AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript

If your website is on a VPS, first byte time can depend strongly on the load. If a lot was swapped out, the first byte times may increase. You may need to run the test several times to work around this.

You can let your server add Cache-Control header lines by adding something like:

Code: Select all

<FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$">
  Header set Cache-Control "max-age=63072000, public"
</FilesMatch>

Thank you so much.
These lines must be added at the end of "httpd.conf" file?
If I have a Virtual Host file, then Can I add these lines at the end of that file? For example, my Virtual Host file is:

Code: Select all

<VirtualHost *:80>
ServerAdmin root@localhost
ServerName myexample.net
ServerAlias www.myexample.net
DocumentRoot /var/www/wordpress
<Directory "/var/www/wordpress">
Options Indexes FollowSymLinks
AllowOverride all
Require all granted
</Directory>
ErrorLog /var/log/httpd/wordpress_error.log
CustomLog /var/log/httpd/wordpress_access.log common
</VirtualHost>
Where is the good location to add that lines?

After adding that lines, the result is:

The Internet speed of a web server play important role or Hardware equipment?
