Can concur. I bought a plugin a few years ago after using the free version for many years, wanting to support the devs for making such a useful plugin. I installed it on a few sites, and left my PC running overnight with a tab open to the plugin and woke up the next day to a lovely rebooted Windows (I hate how default Windows behavior after BSOD is a reboot with ZERO indication that it crashed or if it was an update that rebooted). Re-opened all my tabs, and queue the same waking up the next day to a freshly rebooted Windows, which made me suspicious. I assumed at that point it must have been a BSOD, so dug into Windows event logs, eventually realizing it was Firefox. Restored tabs yet again, left browser open over night, while installing more and more debugging tools for Firefox, none of which helped me track down the culprit. What pissed me off the most was that Firefox even allowed a process to consume > 30GB of RAM and cause my PC to crash! I finally caught it one night after > 10 BSODs - the tab had been open for 20+ hours, and right as it started to spiral out of control and my PC was about to crash, as programs were starting to error out and Windows was madly paging things to disk. I got lucky, and was able to open about:memory to see the culprit - this plugin had some kind of memory leak that wasn't noticeable but then suddenly went nuts. I emailed the devs multiple times with the full debug output, and was ignored for weeks until finally they responded, which pissed me off even more having finally paid for the pro version, only to be greeted with this. The free version didn't seem to have this issue either, which was like an extra slap in the face.

Naked Wordpress is plenty fast, but as soon as you start adding sketchy plugins and Themes, things can spiral out of control.

As someone who built full ecommerce websites on wordpress over 15 years ago, I can tell you exactly why it hasn't been replaced - the plugin/theme ecosystem.

There are tens of thousands of plugins and themes to make a Wordpress website do whatever you want and look however you want, either for free or a very low fee. You have to replace that entire ecosystem for the same price to replace Wordpress.

No matter how many times people get hacked, the perceived value of getting something for nothing outweighs the eventual cost.

Either you use a slow language and deal with caching or you use a fast language and just put Cloudflare/Bunny/etc in front.

> You really shouldn't deploying anything into production without some kind of caching.

Citation needed? You only need cache if a render is expensive to produce.

skill issue being they only know php

Aren’t these optimizations less about PHP, and more about optimizing how your using the database.

What about using the filesystem as an optimized dict implementation?

I agree. The "advanced" leetcode is about those last % of optimization. But when network latency is involved in a flow, it is usually the most obvious low hanging fruit.

Hell, the number of times I've used a lot of the data structures that come up in leetcode exercises without at least looking at some reference material is pretty small. I usually assume I'm going to misremember it, and go double check before I write it so I don't waste ages debugging later.

I did the same thing in PHP before. Issue was a foreach over a foreach with a search. The fix was to build the result set as you populate the main array of objects. Basically as you add stuff to the array if there's a value that matches you throw it into another "results" array for any cardinality (unique value) that exists. Since in PHP objects are always just pointers your results arrays are relatively painless. Just a series of int32 integers basically. Then when you need an answer your result is instant. I ended up getting a 80-90% speed up. This is not just a php thing either. Folks end up doing this type of stuff in every language.
