lurie. I would use vanilla Javascript in the front end. This way, you don’t need to invalidate any server cache. Here is a untested solution. The Javascript File – using ES6 features and forEach polyfill In your main javascript file: ‘use strict’; /** * @summary Clones social buttons and insert them elsewhere * * Clones … Read more
I finally found the setting that was really limiting the number of connections: net.ipv4.netfilter.ip_conntrack_max. This was set to 11,776 and whatever I set it to is the number of requests I can serve in my test before having to wait tcp_fin_timeout seconds for more connections to become available. The conntrack table is what the kernel … Read more
IMHO Your attempt is pointless. On shared hosting you are not going to get consistent results as the results will depend on load generated by other sites on the server, or other sites using the DB server. even worse, the results might change after you have done the testing if new sites were added to … Read more
There is no difference between 1 and 2. Both are same in every single case. So, I’ll consider 1 and 2 as A and 3 as B. Now in A the add_action() callback function is a named function whereas in B the callback function is an anonymous function and this is the main difference. I … Read more
I hate to say “don’t use SATA” in critical production environments, but I’ve seen this situation quite often. SATA drives are not generally meant for the duty cycle you describe, although you did spec drives specifically rated for 24×7 operation in your setup. My experience has been that SATA drives can fail in unpredictable ways, … Read more
When there’s an issue such as yours, there is probably 1 function stuck somewhere that delays the loading. You can retrieve a list of all functions attached to a hook this way: global $wp_filter; $actions = $wp_filter[‘init’] ; Now you can remove the functions from the hook one by one, by using remove_action() and see … Read more
Make sure you run each Pingdom test a few times to average out results! The two things that will most likely account for your difference in results here are : The power and other specification of the server – the faster site is https, so may be able to use http/2; the faster site may … Read more
You need to have a lot of traffic for naive protocol based optimizations to be effective, and even then it is not obvious that you can gain much even when it does kick in. Most people will be first time users of your site, and browser have only a limited space to store information about … Read more
I would recommend tar. When the file trees are already similar, rsync performs very well. However, since rsync will do multiple analysis passes on each file, and then copy the changes, it is much slower than tar for the initial copy. This command will likely do what you want. It will copy the files between … Read more
Horrendously slow admin and pretty slow sites [closed]
