Performance when posting in 3.0.x very SLOW

Post by Daryle » Tue Dec 18, 2007 1:54 am

I've since upgraded from 2.0.22 to 3.0.x. I had to do an offline conversion since my hosting provider wouldn't provide me with the CPU clocks required.

But now when you post (or preview) in the 3.0.x version, after clicking "preview" or "submit", it takes 45 seconds to process. Any idea why this may be or if there is a file that needs to be modified?

I did check the administration panel for settings that may prolong posting but didn't notice anything. Any help would be GREATLY APPRECIATED.

Btw, the site in question can be found here: http://www.hddvdsupporters.com/discussion/index.php
And after seeing how fast preview and submit work on this site, I KNOW there is an issue somewheres on mine.

You could try playing with settings under "Load Settings" to see if that makes much of a difference, although it sounds to me like you may just be suffering from an overloaded shared server.

Wonder about having the RBL checking turned on in ACM security settings, look up like that could cause problems - though I dont know if its used on preview

Sorry, but I dont know the acronyms RBL and ACM... could you please elaborate?

Also, I'm really scratching my head because I don't *think* it has anything to do with my shared server. PHPBB 2.0.x is still blazing fast as is all of my other websites. Is it possible that during the conversion a setting was introduced into PHPBB 3.0.x? I have a test PHPBB 3.0.x site running on the same server and it's really fast: http://www.darylehamel.com/phpbb3/

It's definitely specific to this installation and the only major difference is the new installation involved conversion.

Here was the offender! It was a setting in the Security module:

Check IP against DNS Blackhole List:
If enabled the user’s IP address is checked against the following DNSBL services on registration and posting: spamcop.net, dsbl.org and http://www.spamhaus.org. This lookup may take a while, depending on the server’s configuration. If slowdowns are experienced or too many false positives reported it is recommended to disable this check.

This was ENABLED and took about 45 seconds to post of preview! PLEASE KEEP THIS IN MIND FOR FUTURE REFERENCE! It is NOT enabled by default.

It would appear that rurning off this DNS Black Hole Security setting fixed my slow/freeze message posting issue as well. Thank you! :D

I know this is an old topic but it just solved my problem too. I enabled it the other night and ever since I did it would take ages to submit posts. I won't be enabling it again.

The feature will not be enabled in the next version, it's caused by a malfunctional server to which phpBB is trying to connect.
