 * I just have installed your Plugin at another site.
 * The performance of your plugin measured with P3 plugin profiler could be better!!!
 * I guess you are wasting to much time in the bashboard. One can check that by 
   installing Plugin Logic and ruling out your plugin for Dashboard and activating
   it only on \wp-admin\

 * Hi Hugo and thanks for your feedback. I really appreciate it!
 * That’s interesting. I will check what P3 suggests and if anything can be done
   better then why not? 🙂

 * In order to understand the performances of WP MyBackup dashboard I had to compare
   its performance metrics against some other plug-ins.
    One candidate was WooCommerce,
   which has a rich dashboard with many tabs/subtabs and the other one was BackupWPup,
   which has a similar dashboard like WP MyBackup.
 * The tests consist of a simple walk-through the dashboard settings tabs/pages,
   no action executed (like create an order, create a backup job, run a backup job
   or something like that). I didn’t wanted to compare their execution performances
   but their dashboard loading performances.
    One exception from the above was that
   on the first two tests I run an action (on each plug-in) that “checked the installation”,
   which basically queries the PHP/WordPress configuration. In the third tests this
   action was not executed anymore because I wanted to see exclusively the dashboard
   navigation performances without any extra-functionality.
 * Below is a Profile Report generated by P3, one for each different test:

   0.85% – Wpmybackup – 0.1042 sec – 26.46%
 * **Analysis**
 * We see that all tested plug-ins scored quite the same, their runtime is around
   the 30%, which means an average of 0.1 -0.2 seconds.
    WooCommerce has a bit higher
   runtime than the other two, perhaps it involves many database queries which increase
   the total runtime. On the other hand the WP MyBackup and the BackWPup (which 
   both have a similar dashboard and a similar functionality – they backup the WordPress
   data) have a very close runtime with an average 30.84% for the WP MyBackup and
   respectively 29.3% for BackWPup.
 * Obviously we don’t expect to have an exact match because any of these plug-ins
   queries different amount of data and present different amount of output so a 
   small deviation from a standard is somehow expected. Needless to say that their
   performance is also directly impacted by the available system resources (while
   testing plug-in A the overall system resources might be busier than while testing
   plug-in B). Obviously the P3 cannot handle this level of refinements due the 
   fact that being a PHP process – which is isolated by itself – it cannot monitor
   the local OS resources at that level.
    **Conclusion** The bottom line is that
   their performances, as you have said, could be better. And yes, this general 
   assertion applies to any plug-in or software out there. However, I couldn’t find
   something extraordinary about the performances of WPMyBackup dashboard comparing
   with some other plug-ins.
 * What do you mean by “The performance of your plugin measured with P3 plugin profiler
   could be better!!!” ? Can you suggest something that I could take into consideration
   by doing an in-depth analysis?
 * Anyway, I want you to thank you for your interest in this topic because it helped
   me in gathering this useful information.

 * Compare it with UpdraftPlus. This Plugin takes several actions to reduce unnecessary
   server load.
 * Here is my check:
    BackUpWordPress – 0.0464 sec – 8.05% BackWPup – 0.0232 sec–
   4.02% UpdraftPlus – Backup/Restore – 0.0071 sec – 1.24% Wp Mybackup – 0.2960 
   sec – 51.39%
 * Here your Plugin is permanently over each other plugin. And there a two really
   ugly peeks caused by your plugin. One on a Blog-Page and the bigger one at wp-
   admin/plugins.php
 * PS. Do you know these Plugins:
    P3 Custom Scanner (only on Github!) Heartbeat
   Control Plugin Logic With these Plugins one can customize P3 and take influence
   on the wordpress Heardbeat and the Dashboard performance.
 * Maybe one can try to set DISABLE_WP_CRON to true in wp-config.php for the P3 
   test

 * What did you profiled? (a) The dashboard interface or (b) the backup task?
    Because
   this is important. A test case would be helpful, I mean, I could use the steps
   you made in order to understand what is the difference.
 * In my tests, as shown above, the difference was minimal.

 * Hi Hugo,
 * I still don’t understand how you come up with the above numbers.
 * I did the following test: I just started a P3 profile scan and let it work for
   about 10 minutes then stopped. Meanwhile I did not touched the WP admin interface,
   I was just curious what is going to happen. This is the result:
    - P3 (Plugin Performance Profiler) – 0.0029 sec – 2.56%
    - BackWPup – 0.0554 sec – 48.71%
    - UpdraftPlus – Backup/Restore – 0.0220 sec – 19.36%
    - Wpmybackup – 0.0334 sec – 29.37%
 * Obviously if we make 1000 different profiles (which is the statistically recommended
   way) we might get 1000 different results.
 * I am still confused about how did you got those figures 🙂

 * Hi Hugo,
 * Very interesting topic 🙂
 * I just created a video ([https://youtu.be/Jlm2OnBNpHM](https://youtu.be/Jlm2OnBNpHM))
   about my test where I used the recommended P3 Customizer together with the P3
   Scanner.
 * On the P3 Customizer I’ve added the Settings page link for each of the three 
   plug-ins.
    On the P3 Scanner I just run an automatic scan. **Test #1**:
    1. add the settings page link for WP MyBackup
    2. the same for BackWPup
    3. the link of Edit BackWPup job
    4. finally the settings page link for UpdraftPlus
 * **Note**: the reason behind adding additionally the Edit Job link for BackWPup
   was that its default dashboard does not include the job settings like the WP 
   MyBackup or UpdraftPlus contain.
 * When the profile finished is gave me the following results:
    - P3 (Plugin Performance Profiler) – 0.0046 sec – 1.91%
    - BackWPup – 0.1060 sec – 43.69%
    - UpdraftPlus – Backup/Restore – 0.0634 sec – 26.12%
    - Wpmybackup – 0.0686 sec – 28.27%
 * **Test #2**: the same like test #1 above BUT without (3). The test result:
    - P3 (Plugin Performance Profiler) – 0.0063 sec – 2.25%
    - BackWPup – 0.1003 sec – 35.76%
    - UpdraftPlus – Backup/Restore – 0.0870 sec – 31.01%
    - Wpmybackup – 0.0869 sec – 30.98%
 * **Test #3**: the same like test #1 above BUT without (2). The test result:
    - P3 (Plugin Performance Profiler) – 0.0059 sec – 2.27%
    - BackWPup – 0.0981 sec – 38.12%
    - UpdraftPlus – Backup/Restore – 0.0715 sec – 27.79%
    - Wpmybackup – 0.0818 sec – 31.81%
 * **Conclusion**: within a small deviation from their mean value all of these three
   plug-ins show a similar usage in resources.
 * I would be very grateful if you can compile a test case that can be replicated
   on other systems (eg. my system) which describes in detail what you’ve done and
   what result you’ve received. Your results and my results (documented in the video
   I made public) are quite different and I eagerly want to find out where the bottleneck
   is (if there is any) and obviously to fix it.
 * Anyway, thanks again for your feedback, as always, any feedback is welcome.

 * Hi Hugo,
 * After several tests I think I spotted the problem: it seems that when /wp-admin/
   admin-ajax.php?**query** is called by no-matter-who my plug-in intercepts that
   call and, depending on the **query**, it tries to do `one thing or another` which
   obviously fail. This `one thing or another` may consume resources which normally
   should not be used and thus it increases the plug-in resource usage.
 * I wasn’t able to spot this issue until I have customize P3 in several ways, with
   several custom links, etc. So I noticed that in fact there are other plug-ins
   which call the /wp-admin/admin-ajax.php that leads to accidentally triggering
   of my WP MyBackup.
 * Anyway, I just want to thank you for your incident report, it was a useful one,
   although it took me some time to get probably the same result as you.
 * I will address this issue in the next release, so expect to find it fixed!
 * Best regards,
    Eugen

 * /wp-admin/admin-ajax.php is the so called WordPress-Heardbeat normally running
   all 15 seconds.

 * [10 years, 5 months ago](https://wordpress.org/support/topic/performace/#post-6767420)
 * You are right: Heartbeat is one of the many things the admin-ajax.php does. Additionally
   the admin-ajax.php script will load the WP bootstrap, administration API, WP 
   Core’s Ajax handlers. Each of these will load other WP scripts which may trigger
   many other actions/filters.
 * If your plugin listens any/some of these WP actions/filters then obviously the
   plug-in will use some resources when the hook(s) gets executed. If the above 
   hooks fire several times and your plug-in should, for instance, listen/execute
   only in one particular situation (eg. on dashboard page only), then the unnecessary
   spent time is multiplied such that 0.5s could mean in real-life even 5s.
 * Anyway I fixed the issue, thanks to your incident report.
 * Now, during the normal Heartbeat, the WP MyBackup uses only 31% (0.035s) where
   the UpdraftPlus takes 18% (0.021s), BackWPup 47% (0.054s) and the WP Core takes
   the rest (4%).
 * So 0.035s(after) vs 0.296s(before) is 8.5 times better. Not bad. Could be better?
   Yes, but it requires some refactoring which I will schedule for January release.
 * Again, thank you for your report & feedback.
