After upgrade to 2.7 – very slow

@otto42
Sorry, that’s the old “game” – my provider tells me that there must be something wrong with WordPress – you are telling us that it must be something wrong with the server – period – other word: a blocked situation.

There is one important difference: You give your provider money. You have not given WordPress or anybody else here anything.

I have no reason or inclination to lie to you, so why are you assuming that I am?

To switch the server or to switch the program is not a solution in my opinion.

Then I suggest that you fix the problem on your server instead.

My goal: To find and solve the problem. But I don’t have (root) access to the server and I have only little skill in PHP.

Then I suggest that you find somebody who can debug the issue and pay them to fix it.

Or switch hosts to one who is more supportive of your issues. We cannot make your hosting service magically work properly.

Yes I know, to find a problem one must have a lot of information, as much as possible. But it is not so easy to give such information – to test software and find bugs in not all users daily business.

And that’s exactly my point. We can’t help you because you don’t have the access or information we need to help you. We really can’t even tell you what to look for. All we can do is give limited advice.

You need your host to figure the issue out. And if they won’t do that, well, then you’re kinda screwed with them. Switch hosting providers to one that works properly and provides support.

On the other side: If you have a lot of feedback about “slowness” of version 2.7 there “must be something”…

Actually, I have not seen a lot of feedback like this. There are a couple cases I’ve seen of the HTTP API blocking because of sites having disabled some functions, and some people have slowness posting due to large numbers of XMLRPC ping sites in their settings, but no, the reports of this are rare.

@otto42
Seems that not all WP staff has your opinion – to my trac-report I got nice and interesting feedback and with the suggested patches we could find more details.

Yes, I did see the trac report you posted. DD32 made a guess and got lucky with curl being part of the problem.

However, again, the problem is on your server. If your provider is using some funky versions of curl and other software, WordPress still can’t fix that. Like I said before, at best it can try to workaround your funky broken server issues.

You’re still better off switching hosts.

The problems described here are comparible to the problems I am having since having installed WordPress 2.7. I have tried to start with a clean install instead of an upgrade, which didn’t have the effect I wanted. The loading time of pages has gone from quick (as it should be) to +- 4 seconds per page.

Downgrading to WP 2.6.x resolved my problem, so I am now back on 2.6.x.

I also installed 2.7 on a different host, where it worked perfectly fine: quick loading times as it should be. Maybe I could be of help in solving this problem by comparing the two server settings?

ps: great work on the 2.7 admin interface!

@otto42
Could you please tell me which version of libcurl WP 2.7 must find on the server?

To solve the problem, SSH to your server and edit /etc/my.cnf .

Add:

log-slow-queries = /var/log/mysql-slow.log
log-queries-not-using-indexes
long_query_time = 1

or something similar. Then install mysqlsla and parse mysql-slow.log, and it will produce some nice stuff.

Take that information to phpmyadmin, and use EXPLAIN on the sql queries, and post THAT information here.

Thanks for your help – but I don’t have such an access to the server and can’t install software.

I try to send the information to my provider – but he told me that there is no known problem on the server (sic!).

@ Otto,

Same thing here Otto. Everything worked perfectly untill the installation of 2.7!!! After that the loading of the dashboard slowed down terribly. If several users experience that problem I think that calling it “NOT A WORDPRESS PROBLEM” does not really help. Allright I don ‘t get load times upto 5 minutes but performance has decreased considerably where a performance increase was promised. Ans please don ‘t misunderstand. We all appreciate the work and effort you put into answering questions here.

Cheers Berend.

No, I didn’t try the patches you mention. I followed the link but I simply can’t understand what is going on there.
Thanks for answering, but after spending literally hours on this, I think it would be more productive for me to explore ways of going back to an earlier version of the program.

@johonbakeronline
Ok, I understand your decision. But well it would be interesting if the patch could solve your problem – perhaps this would help to find a real solution about this issue.

I know nothing, but I could guess it could be a bad table in your database. That was what it was on one of my other wordpress sites.

Anyways, it probably is my server, but if it is the database, then I will tell you.

I found an other problem: With the patch loading time is better now – but changes in sidebar widgets are not stored correctly. In widget setup page the changes are displayed correctly – but when leaving the admin and going to the blog pages the changes are not displayed.

If I use the unpatched http.php the changes are stored correctly.

Other way round: Without the patch I am not able to update a plugin automatically – with the patch it works.

I have the same kind of problem: after upgrading to 2.7, first it worked great. Three days ago, the admin menu started to get really slugish. Around the same time,I got the a new upgrade-mag screenm, like the ones talked about here and here.

The strange thing is 2.7 worked flawless for a week or so. There weren’t any changes on th server, at least what I know about. Any ideas?

OK, I solved it already. Was a super-cache something.

I’ve got the same problem. WP 2.6.3 was running fine. Upgrade to 2.7 and now it’s take over 1 minute to load the main page whereas before it was a second or 2. And it’s definitely not my server because I still have another 2.6.3 blog on that same server and it flies.

I’m not familiar enough with this stuff to be able to diagnose the problems, but I’m on a shared linux hosting plan with 1and1 and I’m having horrible slowness with 2.7.

And mods like Otto make me want to leave WP altogether. This seemed like such a helpful and cooperative community but his attitude has totally soured me. Telling everyone their servers are broken and funky is not helpful. Less confrontational and dramatic language would have been much more helpful.
