Too many preloads is bad for performance

…. but a flicking site due of re-rendering after loading fonts that have different proportions is absolute eval.

Thank you, Daan. Now it works as I would expected with adding version to file-name.

I would just add regeneration css-file (not the entire set) while updating, otherwise the updated plugin clients know nothing about the great future that you have just added and will suffer on without this future.

Regarding 2,5% of browser users: it’s a lot. There is just a few or even noone IT-specialists among them, but, say Warren Buffett among them. But it’s very unlikely that he writes a claim to the plugin support blog. He just get out from the site opened on his IE11 on his Windows7 ??

Hello Daan,
Sorry for the delay.

I have checked out your Beta and figured out that you have put in just a part of the great job:
1) you have put in version to css-file that is great but it works out just after manual refreshing cache (I’d make up that the new version should reconstruct css-file at update).
2) you have forgotten about “Load Early” links (it still keep suffering unversioned):
<link id=’omgf-preload-0′ rel=’preload’ href=’//test.com/wp-content/uploads/omgf/roboto-condensed-font/roboto-condensed-normal-latin-400.woff2‘ as=’font’ type=’font/woff2′ crossorigin />

One thing more that I didn’t mentioned before: it would be even more great if plugin created woff -file too (cool people still use outdated appliances).

I believe that the community will pay attention to the terms and the figures of speech used in the comment and recognize and respond to this hate speech.

2. Formatting results plugin adds span block with display:block; attribute that breaks the either formatting and that is quite difficult to correct by html of %QUESTIONS_ANSWERS%

Hello Sumit,

I have caught an example of destroying text by plugin’s admin edit form. It’s not exactly that I described above but it’s reproducing well:

Another thing is that the plugin is doing something similar applying the template for output the result. I even had to make another plugin to fix bugs of your plugin otherwise it outputs ugly.

Really, it would be much easy to type html to textarea field then to fix that “smart” edit helper destroys. Any way to set something smart, inputing html is unavoidable.

Hi Sumit,

I made 1 quiz with 4 questions in 2 categories (2 questions in each category) and set in options:
Limit number of Questions: 2
Limit questions for each category: Y
Select Category: CatA : 1
CatB : 1

Random Questions?: Disabled

Questions Per Page: 0

Enjoy the result: https://forcesail.ru/tests/test-1/

Hello Sumit,

regarding the 1st question: it’s not a problem to summarize a few simple numbers of questions per category mentally to input this number “limit on the total number of questions for the quiz” field (let’s accept it as a test of cognitive abilities ?? ) if it’s difficult to do it programatically :))

The problem is that there are a lot of plugin errors that come to the same result – quiz output all it’s content to the same page.

Another thing with there setting is that if to set “limit questions per categories” and “Random Questions” together than plugin mixes all questions from all categories together instead of in the sequence of listed in “Select Category” categories output mixed questions from 1st listed category than from 2nd and so on.
So, for example if one wish to prepare math test with increasing difficulty like:
– to show 5 questions from 50 like 2+3=
– than to show 5 questions from 50 like 21+34=
– than to show 5 questions from 50 like 231+354=
it’s imposible: all 15 (=3*5) questions will be mixed. The only solution is to prepare 3 quizzes per 5 questions from 50 that is annoiable to do them.

Hi,

Unfortunately removing other widgets doesn’t help

it was great until v4. Would you return the admin interface from v.3?

Hi Slava,
many thanks for clarifying your understanding of how AS works.

You are write, AS sponge wp-cron, that originally acts when a request comes to server. This is exactly the problem with AS, that set every-minute wp-cron task where it (every minute!!!):
– allocates the whole server memory (it takes time) displacing all from it,
– checks the DB structure (these DB requests takes time) (no one of other plugins of core functions never check DB structure every time it use it),
– checks wp_cron tasks and if it deleted – restores it (so, it’s imposible to stop AS acting even if it’s not used)
– some actions more for itself

– then memory return for useful php (and it takes time again to reload php and caches)

If you think that such activity is not malware – just clarify me what is malware in your understanding.

In mu case, I spent a lot of time to investigating why my site is so slow that google and yandex informed me that they crossed it out from search list. Once I found that every server request starts with extra activity I found just 1 plugin (it is SEO plugin that destroys all SEO for sites) that uses AS. As I hacked it to avoid AS activation my site improved response from 7s to 1.1s

I can repeat, that sites that optimized for hundreds requests per minute can not to be under influence of AS activity (big woocomerce site, for example). It is as with any malware: until hardware is powerful it’s very difficult to notice a malware by it’s activity. But once one get it on netbook – it’s even more than noticeable. The same happens with shared hosted sites.

Your plugin is great but it brings malware that your plugin even don’t use.
So, unfortunately, I have to state that ?PDF Embedder currently is mortal danger for sites. I’m sorry.

But I believe that you avoid AS in the upcomming upgrade and the plugin will be even better and safe!

Hello Slava,
many thanks for the prompt and very detailed report.

Unfortunately, Action Scheduler is much more malware than you think: once it activated it schedule itself for every minute action, even if it’s nothing to do. It starts with occupying all memory displacing all other processes and makes a lot of SQL requests. it happens every minute!! Until I cleaned my site out of this malware the initial server response was 7s, now it’s 1.1s.
Another thing with this malware is that it’s imposible to stop it: it recreates immediately by itself. It’s imposible just to remove it – it generates WP core error.

So, even when you don’t track the site Action Scheduler acts against site, slowing it down.

Probably, sites that serves hundreds and thousands requests a minute, can be interrupted once a minute without a problem, but sites that acts on a shared hosting slow down up to be blocked by search engines (Google, Yandex and others).

Sorry for the delay with the response. I used this time to test the issue more carefully.

it seems that the issue was fixed in one of the recent updates so currently it acts as you explained.

Sorry for the wrong report.

Hi Sumit,

unfortunately this CSS don’t affect on the issue at all.
My user-defined CSS: https://forcesail.ru/wp-content/plugins/ag-qmn/qmn_forcesail.css

When you try https://forcesail.ru/tests/sails-stream/ please don’t pay attention on the JS Alert() – it comes from my code that is definitely not interfere with the plugin.

Hello Sumit,
Many thanks for your helpful.

Of course that I tried it as well. Unfortunately it doesn’t work too.

I suppose it doesn’t work because there is no html tag with class qsm-d-none. You can check it by yourself: https://forcesail.ru/tests/sails-stream/

Hello Sumit,

thank you for the opening this secret :)) But what is bad to output title (if it’s not empty) too?
