bootstrap3-template takes 10 times longer to load pages than dokuwiki-template for large pages

Large pages take long time to load

Normally we are using bootstrap3-template. Currently I have investigated that with very large pages with a lot of includes inside it takes 10 times longer until they are displayed if I use bootstrap3-template compared to dokuwiki-template and compared to about 5 other templates; I already "had to" increase "max_execution_time" in php.ini from 30 to 60 in order to not run into a time-out. If a page of that size just contains text time differences are not that noticeable.

Has somebody got any similar experience and/or can guide me what I can do to investigate the "problem" further?

Sorry, there is a bug label added to this post. This was not the intention. How can I delete it?

Hi @virk, Bootstrap3 have an internal parser for convert some DokuWiki HTML output in Bootstrap compliant output and sometimes is slow with long pages.

What's your DokuWiki and template version ? Your Wiki is online ? It's possible to have the source of the slower page ?

Dont' worry, the label is automatically added by GitHub. I've just removed this tag.

Hi Joseph!

The wiki is an internal one and currently I cannot grant any access. Dokuwiki is Greebo (up to date) and bootstrap3 also up to date. Some further information:

The page is just the following:

====== 2789 Heading ======
{{namespace>projekte:2751_2800:2789&depth=1}}

But the namespace 2789 contains about 200 small pages which are included automatically via the include-plugin and by the above mentioned {{namespace>projekte:2751_2800:2789&depth=1}}

Most of these about 200 pages look like the following:

==== 09.08.2019 ====
  * Phone call with Mr. X done. He agrees, that this was best joke ever.
  * Answer sent to Mrs. Y. She wants to
  * Additional approx. 10 lines

Some of these 200 pages also contain some data-table and/or some pictures.

When I press reload the page gets blank and the text gets visible back after approx. 35 seconds. (I increased "max_execution_time").

On another (faster) machine (mac mini late 2014 Mojave, php 7.1.23) I tested with loadskin-plugin and "reload" via click on the breadcrumb the following:

• Bootstrap3 15 sec
• bootie, dokuwiki, ghw, monochrome, sprintdoc, twentyfifteen, arctic (here text did not disappear at all). All these reloads took about 2 seconds, some slightly more, some less
• Bootstrap3 12 sec

When I look into the web-information during this reload phase it seems, that everything is loaded within milliseconds but the "projekte:2751_2800:2789" takes 13 seconds. To me it seems that httpd is busy 100% during that period.

To be mentioned is "If a page of that size just contains text time differences are not that noticeable."

If you have any idea what I can further support with kindly let me know!

Hello, I have same behaviour on my setup. I'm running dokuwiki on LAMP setup inside Proxmox>LXC container. Recently I've moved dokuwiki directory to glusterfs storage. TTFB is now between 3 and 6 seconds. When files are local to container, it was like 150ms. If I switch from bootstrap3 to dokuwiki theme, it rarely reach 1s TTFB. So, yes, moving from local to glusterfs has a cost, but using bootstrap3 theme, it becomes inusable. We are using sidebar to navigate namespaces. So I need simple navi plugin at least...

There are news from my side: I installed Catalina macOS with php 7.3.8. With this combination the wiki with bootstrap3-template gets fast again. I do not know what it is due to but with php 5.6.30 or 7.1.23 it is still that slow as written in my initial post.

edit: fixed by installing php-xml for 7.3

FYI: On ubuntu 18.04, after installing php-fpm-7.3, the search functionality breaks.

@issmirnov, seems you don't have php-xml package installed

[issmirnov]

@giterlizzi thanks, I had installed it for 7.2 but not 7.3. Happy to report this fixes the crash seen. However, my benchmarking shows no speed improvement between the two PHP versions.
