How can we save Ram usages using some wordpress theme tricks

While running wordpress site, save Ram usage is always great idea and you can easily improve the site performance by simple wordpress theme tricks.

We mostly use the get_permalink(), get_the_title() methods in our wordpress theme. Do not pass the post ID as parameter.

if you’re doing a get_permalink or get_title() call with Post id, 8 out of 10 times you’ll need to more of that post than just the permalink, so this isn’t really a problem.

save Ram usage

Post object is actually already slightly faster than calling get_permalink with $post->ID (in get_post it then only sanitizes and adds to cache, it doesn’t fetch new data), but the real benefit comes when you add a variable called filter in the $post object, setting it to “sample”. Now you decide whether that post object is going to be cached or not and which variables it contains.

Pass the $Post object instead of Post ID.

Do not use the Custom fields. Your server need to fire extra custom quries on Mysql server.

If your are using $wpdb->get_results or new WP_Query( $args ) then add the order by.

If wordpress site is hacked then how to fix issue

There is something wrong happening on server.

First thing I did which is checking the apache access logs and error logs. I was getting per second 100 request from some IP addresses.

I stoped apache server and I took my database and filesystem backup. Deleted my admin username and added new administrator with new username.

You should use the Better WP Security wordpress plugin. This is very useful plugin.

I added following code in my .htaccess file

 # BLOCK BAD IPS
 <limit GET POST PUT>
 Order Allow,Deny
 Allow from all
 # uncomment/edit/repeat next line to block IPs
 # Deny from 123.456.789
 Deny from 192.111.152.122
 Deny from 192.111.144.233
 Deny from 110.85.90.123
 </limit>

But above code was still not helpful to me because disk I/O and apache process was taking time to sending the request to 403.

Then I blocked the IP Address on My Linux server using following commands.

 iptables -A INPUT -s 192.111.144.789 -j DROP
 iptables -A INPUT -s 192.111.152.122 -j DROP
 iptables -A INPUT -s 192.119.144.123 -j DROP

This solved my issue.

WordPress Under Huge Attack by Malicious Botnet: Protect your WP

From last two months WordPress Under Huge Attack by Malicious Botnet. Hackers are using thousands of individual computers and IP addresses. The botnet goes for the most obvious hack attempt: target sites with admin as the username , and will try to access that site’s password with a combination of thousands of possible passwords.

The WordPress site currently powers over 60 million websites and read by over a quarter of a billion users every month.When survey website W3Techs conducted a survey, it was found that 17% of the world’s websites are powered by WordPress.

While the attack may only succeed a small percentage of the time, the attack could result in hundreds or thousands of compromised servers when averaged over tens of thousands of sites powered by WordPress software.

I recommend following solutions for handling this issue
Change your WordPress admin Username

We can use the following article for changing the admin username

Use the Better WP Security plugin
As most WordPress attacks are a result of plugin vulnerabilities, weak passwords, and obsolete software. Better WP Security will hide the places those vulnerabilities live keeping an attacker from learning too much about your site and keeping them away from sensitive areas like login, admin, etc.Better WP Security takes the best WordPress security features and techniques and combines them in a single plugin thereby ensuring that as many security holes as possible are patched without having to worry about conflicting features or the possibility of missing anything on your site.
