After installing PayPlans, we noticed that the site started to become very slow.
We also saw a huge spike in CPU usage, with almost 100% usage of 8 Xeon CPU's.
Page loading times also spiked, from a pre-payplans load time of a few seconds to times ranging from 20 seconds to 90 seconds.

Eventually we tracked the problem down to the PayPlans System plugin.
Disabling the plugin improved system response time dramatically, with site loading speeds for the non logged-in landing page dropping from 13 seconds to 3 seconds (at 3am in the morning and minimal user load)

In the attached GTMetrix report, you can see the difference quite clearly, with the difference being some 18 seconds extra loading time when the PayPlans System Plugin in enabled.

How do we resolve this issue?
Does the system plugin need to be enabled?
What does it do?

Installing Payplans and enabling the system plugin effectively makes my site unusable.
Members are complaining and we are already seeing a significant drop in the number of site visitors.
Just so that you can get some idea of how serious this is.....

Is there any time estimate on this?

Unfortunately we don't have time to wait around for yet another version to be released.....at the rate of online member attrition we are experiencing as a result of this performance hit, we won't need a fix as we won't be in business any longer.
This is a CRITICAL issue and we need a fix URGENTLY!

In the meantime, the only way we can get our site to be usable is to switch off the PayPlans plugin.
Please advise what impact this will have on PayPlans.

Thanks Manisha,
The new update seems to have fixed the issue:

  • CPU usage dropped to 2000 Mhz ( was 18 000 mhz, equivalent of dropping from 8 x Xeon CPU)
  • Homepage loading speed now 4.1 seconds (was 70 seconds)
