Re: Intermittently slow forum

Well, it doesn't seem to be anything to do with the phpBB code, which manages to complete all it wants to do in a few hundred milliseconds.

So it's something lower-level on the server.

Re: Intermittently slow forum

I have other ways to work out where the slowness is coming from. I don't really want to break functionality at this stage.

Re: Intermittently slow forum

The trouble is that there are a lot of asynchronous and synchronous tasks going on, and there are a lot of clients sending requests to the Forum server all the time. Most likely candidates are: ⋅ Database table locking (unable to write to the table until the last write has completed) &sdot...

Re: Intermittently slow forum

Thank you for the feedback. It's probably not down to email sending holding the forum up, then.

More likely a database table locking issue. I'll investigate further.

Re: Intermittently slow forum

Not unless someone spots a pattern.

I've made another change...

If it's email sending, hopefully that will fix it.

Re: Intermittently slow forum

Seems to be a problem other people are having: https://www.phpbb.com/community/viewtopic.php?f=466&t=2461011 I've tried all the obvious things, and suspect it's something to do with emailing notifications. Perhaps worse on busy threads, or threads with lots of quoted text, which might result in ...

Re: Intermittently slow forum

OK, if it's only posting that's slow then it's probably a database table locking problem.

I'll have a dig.

Re: Intermittently slow forum

Piwik/Matomo says the average page generation time (including client-side rendering) is only 0.3 seconds or less.

I wonder where the problem is...

Re: Intermittently slow forum

No obvious overloads on the server. I have plenty of alarms that go off if it starts having to work hard.

Can you tell me more about the slow pages?

Are they always when you post a new comment, or also when you are just browsing and reading?

Re: Intermittently slow forum

There were some nasty network problems last Friday, but those have been fixed. Is it still intermittently slow?

At a particular time of day?

At a particular time within each hour?

Randomly?

Re: Missing link?

The problem occurs because the definition of a "pixel" size has changed in recent years. In The Old Days screens generally had 75 or perhaps 150 pixels per inch. These days high-resolution screens on mobile devices happily go to 300 or 400 pixels per inch. On these high-resolution screens,...

Re: Missing link?

For some reason the phpBB developers decided to hide this link for screens less than 500 pixels wide.

I've updated the style so the link appears on all screen sizes now.

Re: Misbehaving return key

OK, that could make sense as the square brackets are meaningful "code" so there might well be JavaScript working when you are typing near them.

Which browser are you using?

Re: Misbehaving return key

That's odd. Sounds like a JavaScript problem somewhere.

Does this happen when you're typing just text, or only if you've inserted something like a list or formatted text?
