Hello,

I am having continued issues with WP Amelia spiking CPU usage to 100%.

I am running the plugin & website on a server with significant resources but WP Amelia specifically seems to spike the CPU usage to 100% whenever a user attempts to load the event list.

This has been an issue for some time and your team addressed it saying they were working on performance, but it seemingly has only gotten worse to the point that the plugin is practically unusable. 

I am hoping you may have some steps to increase performance or advice on what we can do.

Some further information from testing:

A single user accessing the website and navigating to Amelia causes the following spikes

RAM Usage

Went from 2.13 to 3.83 GB in use

CPU Usage

Went from 29% to 80&, often spiking to 100%

This is on a Cloudways Vultr HF server with 

4 GB RAM, 2 Core CPU, 128 GB Storage, 3 TB Bandwidth

There are other applications on this server, but only interacting with Amelia causes spikes like this. Other websites fluctuate up and down are a usual amount.

This is very concerning that Amelia has such a performance on what is an otherwise powerful & stable server.

Hey Stefan,

Great to hear that it loaded for you and I appreciate you looking into it.

I ask you to keep in note all the details I shared with you. We have been experiencing constant complaints on websites with Amelia and noting that each is sucking up way more CPU/memory than ever expected to the point that the server crashes.

I just ran another test and the CPU went from 22% to 88% by simply opening the event list.

This has been extensively tested with my hosting platform and by myself and every detail points to Amelia causing excessive CPU spikes and memory issues.

Do note as well that this specifically became an issue when I updated the plugin. I was running old versions as far back as 6.7 - 7.0 for a while due to the many bugs found in newer versions. I recently tested & updated as things seemed stable but now my websites are practically unusable. 

No classes will load in my event list at all on my website now.... hoping someone can help with this as this is a live business that now cannot make any bookings due to this plugins failure. 

I downgraded to a previously stable version to test as it was working better before. This actually did somewhat decrease demand on the server, but we were still running into the same issues.

Due to the urgency I have now moved the website over to its own server.

Immediately upon opening Amelia the CPU spikes to 70+ %.

Amelia is using 70% of a powerful service with 4 GB Ram + 4 Cores on Cloudways. That is a crazy amount of resources demanded. 

The site is currently propagating to use the new server IP, I will update the plugin again then but please note the differences in performance noticed. 

The plugin is updated and waiting for your assistance, thank you.

Hey Stefan,

We've run this system for a long time without any issues, so it is strange for it to pop up all the sudden.

We need a way to make it easy to navigate between event categories (tags?) which your tool doesn't over natively which is not very user friendly. This makes it really difficult for a customer to find an event. As the studio has many different event types we can't just mix them altogether.

I figured that being in a tab they would not load until the tab is opened. Why do they load when they are not visible? Can this be avoided?

Or do you have any other recommendations? 

Hey Stefan, this sounds like a great solution but I am having trouble implementing it / getting it to work. I added the code in as you suggested but mine do not work.

Your example: 

[ameliaeventslistbooking tag='Music Lessons' trigger=music-lessons trigger_type=id]

Examples I put in:

[ameliaeventslistbooking tag='Bopping Babies' trigger=bopping-babies trigger_type=id]

[ameliaeventslistbooking tag='Tiny Classes' trigger=tiny-classes trigger_type=id]

[ameliaeventslistbooking tag='Mini Classes' trigger=mini-classes trigger_type=id]

Am I missing a step here? I had to revert my changes as nothing would display when I tried to open the tabs.

In your message you used underscores, but in your example you showed dashes. I tried bopping_babies and bopping-babies but neither works. 

Your assistance is appreciated. 

Thank you Stefan. This seems like an excellent solution.

Perhaps it should maybe be incorporated by default to avoid performance issues with Amelia?

Looking forward to further performance improvements as well.
