Registration anomalies due to traffic

My license may have expired but I would appreciate an answer from support because I’m considering switching to Event Manager.

In previous registrations the crush of traffic has led to our site going down; this has been resolved with a better server (cpu & ram didn’t spike at all this time). This time the site did not go down but the registration process was messed up for a lot of people, including not getting a choice of payment option.

I’m not sure if EE can handle a lot of traffic at one time or not. I’ve previously posted how tickets are often oversold when people register at the same time (which really makes ticket limits pointless). I want to know what kind of traffic EE can reasonably handle.

Hi Arp,

A single codebase installation of Event Espresso 4 handles all of the traffic coming in at eventsmart.com. I don’t know the number of registrations coming in every minute over on that site, but it’s a significant number. If your hosting costs/issues are a concern, you might consider hosting your events on eventsmart and leave that part to them.

Are you saying that site is 1) built on EE, 2) lets people create free events and 3) that it handles all registrations flawlessly?

Yes to all three and it also lets people sell tickets for not free events too.

There’s a slight flaw in comparing EventSmart to a single install of EE: all the concurrent registrations are *not* for the same event. Do all event use the same db table?

Hey Arp,

Each site has its own tables, are you familiar with WP Multisite? Eventsmart is running WP Multisite with Event Espresso. Your question was whether EE can handle a lot of traffic and Eventsmart is a good example that shows it does. They’re aware of some of the higher traffic sites on hosted there selling tickets out in minutes.

May I ask were you using a shared hosting plan when you used Event Espresso before? If so what kind was it?

It’s a cloud hosting account, I have control over the CPU & RAM, neither of which budged during registration (previously both were exceeded during registration, causing the hosting to crash; I’ve since increased CPU & RAM). The mysql server I don’t have control over.

The install is also on WP Multisite, which only a handful of networked sites whose total daily traffic averages around 100-150 visitors max. I don’t believe that other traffic would affect things much as it’s spread out throughout the day.

Ever since we’ve used EE, we have *always* had several tickets oversell, resulting in negative availability . Instead of ‘Sold Out’ it says ‘Not Available’ with ‘Spots Remaining’ a negative number. You can see it right here.

That’s a major issue for us, along with the lack of a wait list (which I do understand is not necessarily a feature that EE needs to offer most of your customers).

Hey Arp,

Your site has a really old version of Event Espresso and since that version’s release there has been a lot of work done on optimizing writes and reads to the database, preventing overselling, and tracking sale counts.

I can suggest trying out the latest version (it’s available for free on github) and you’ll likely find the major issue will not be an issue anymore.

https://github.com/eventespresso/event-espresso-core/

If you’re interested in trying out the the wait list add-on on a development/testing site, it’s also available to download here:

Please note that the wait lists add-on is still under heavy active development so it’d be best to not use on a production site yet.

Also, the code that you’re using to display spaces available is something that was added with a customization, because the standard ticket selector code doesn’t include a column with that information. If you need help with making that customization say “sold out” when that spot is sold out, I can help you with that if you can post the code to a gist or pastebin and link here.

Thanks – we will try the update & the test the waitlist option too.

I’m not worried about the Spaces Available as it should be fine as long as tickets are not oversold.

Question: is there any option (or plan for one) to connect purchases to WP user accounts, thus letting people review their purchases?

Thanks to for all your help so far.

Yes that’s available as a feature with the WP User Integration add-on. There’s some information about that feature here:

Does the addon allow people to save their contact info so it’s pre-filled for future registrations?

Also, is it possible for someone to edit their registration or add/remove a ticket?

The add-on will populate the contact’s First Name, Last Name, email address to the registration form when they are logged in with their user account. They can go back later and edit registration form answers (from prior registrations). It doesn’t allow for adding/removing tickets from a previous registration.

Thanks. That doesn’t sound like it will add a lot for us. The waitlist feature might be enough.
