"502 Bad Gateway" while I enabled it on. --Liuxinyu970226 (talk) 05:14, 26 March 2014 (UTC)
 * Yep. It sometimes does that. Please read https://translatewiki.net/wiki/Thread:Support/HHVM so you know how to escape it in the future. --Nikerabbit (talk) 07:21, 26 March 2014 (UTC)

Laymen
If you'd like more people to try the beta, putting this page in laymen's terms would help. What are "performance improvements"? Does it mean that I'm going to load pages faster? Save them faster? Ed [talk] [en:majestic titan] 17:44, 20 September 2014 (UTC)
 * Have you really read the page? :) For your question especially the section What will HipHop do for our end users? --Florianschmidtwelzow (talk) 18:00, 20 September 2014 (UTC)
 * Sorry for the confusion, but I'm talking about the lead, which is what most people will read before giving up! Ed [talk] [en:majestic titan] 03:03, 21 September 2014 (UTC)

Not enabled
The instructions say, "You can verify the feature was enabled properly by visiting Special:Version on your wiki, and checking that it says "HHVM"." I can't find "HHVM" on the page, even via a search. I'm on enwiki. 67.166.124.229 19:49, 22 September 2014 (UTC)
 * It's in the box at en:Special:Version. :) Quiddity (WMF) (talk) 01:12, 23 September 2014 (UTC)
 * … if you enabled it in the preferences. --Tim&#160;Landscheidt 01:22, 23 September 2014 (UTC)
 * I did enable it, but was nowhere to be found on Special:Version.  I searched the page for "HH".  My edits had no Tags: HHVM.  Ten minutes ago, it finally popped up on my edits.  User:Bgwhite 08:28, 23 September 2014 (UTC)
 * Ah! Whoops. Thanks. Quiddity (WMF) (talk) 18:49, 24 September 2014 (UTC)

HHVM enabled
I see that I took a look at my contributions on Wikipedia says that the tag like this "(Tags: HHVM)" has enabled for recent edits. -- Allen talk 02:38, 23 September 2014 (UTC)

No caching for logged in users
If, as is suggested, "By definition, users that are logged in cannot be served pages from a static cache, as the page served to them must include user-specific HTML such as their username at the top right of the page. This, unfortunately, creates a situation where simply logging in causes a tangible decrease in how well our sites perform for you", then why does the page Israel load to view in less than second whether I'm logged in or not, yet take about 13 seconds to preview an edit or save a change? Are you sure nothing's cached for logged in users? --RexxS (talk) 21:20, 23 September 2014 (UTC)

What really is this?
And why have these HHVM tags been appearing on several users' edits on Wikipedia and Wikimedia Commons? Are they somehow using this to edit? This page isn't clear enough to end my confusion. Dustin V. S. (talk) 02:59, 25 September 2014 (UTC)
 * Ah, I see that it appears as an option when I go to Special:Preferences. Dustin V. S. (talk) 03:03, 25 September 2014 (UTC)

link
When i click to link on Special:Preferences, I got this page. And there is written my issue. JAn Dudík (talk) 05:29, 26 September 2014 (UTC)
 * I put a redirect there to this page. There was no content before that, just a redlink. Now the redirect is broken as well.  09:34, 27 September 2014 (UTC)
 * No, I'm pretty sure there were discussions on that board. Pinging User:Quiddity (WMF) to see if he can fix this. Best, --Elitre (WMF) (talk) 09:37, 27 September 2014 (UTC)
 * History does not show any. Deleted the page, but still locked in fatal exception. Please restore the redirect.  13:48, 27 September 2014 (UTC)
 * I've emailed the dev team, to see if anyone can fix this over the weekend. Sorry for the trouble. :( Quiddity (WMF) (talk) 18:00, 27 September 2014 (UTC)
 * Is this means, until bug fixed, we shouldn't use Flow Extension to discuss this? --Liuxinyu970226 (talk) 05:08, 28 September 2014 (UTC)
 * The page is accessible again now. Quiddity (WMF) (talk) 17:12, 28 September 2014 (UTC)

403
When I have HHVM enabled on enwiki, I can no longer pull local static images like this from the server; I am getting intermittent 403 errors. 09:35, 27 September 2014 (UTC)

Bad link:
Clicking on preferences, then beta features on Wikipedia and then the discussion part on HHVM takes you to this page:

Talk:HHVM/About

Which gives this error:

"[974ca5ba] 2014-09-27 13:35:25: Fatal exception of type MWException"

--Harizotoh9 (talk) 13:36, 27 September 2014 (UTC)


 * See above.   13:53, 27 September 2014 (UTC)

Big Pages and Lua Timeout

 * Big Pages don't work with HHVM (de:User_talk:Merlissimo as a example)
 * In some a timeout-error is thrown (e.g. Beta test for template webcite). We have some real world pages (e.g. Fukoshima-stuff) where this timeout-problem could appear in production with rising usage of Lua moduls.
 * Performance with HHVM is better then old php stake. Thanks a lot! --Boshomi (talk) 20:12, 28 September 2014 (UTC)
 * I can confirm the first point. A "503 Service Temporarily Unavailable" error occurs when trying to edit an existing passage at the given usertalkpage. Trying to add a new passage, no error appears. --Ali1610 (talk)

The length of a page is not the only reason. I think there are some html-Elements that cause the errors. Boshomi (talk) 21:29, 30 September 2014 (UTC)

This is awesome
Just so that the team who worked on adding HHVM support on the servers know: this is freaking awesome. Turning on HHVM seems to be making editing Wikimedia sites snappier and more responsive. Ajax requests fired off by JavaScript widgets seem to complete quicker. I was doing a bunch of maintenance tasks on Wikipedia earlier while on a train on a rather dodgy 3G connection and it was a lot less painful than when I last did the same pre-HHVM.

Give yourselves all a pat on the back: every speeed up to editing Wikimedia projects makes it so that heavy users who do lots of routine maintenance tasks can do so a lot quicker, which means they are more likely to do so. —Tom Morris (talk) 15:38, 30 September 2014 (UTC)
