Asking for patience in advance, as I am not that technical.
My forum takes several minutes to load any page for many members but not all. Especially any page that returns unread posts or topics. Regardless of which browser they use. I was not sure if the problem was on their end or mine, so I searched this forum and learned that I should enable "Display time taken to create every page" to determine exactly how long the pages were load. I asked them to report how long each page was taking to load - did that and determined the site was, in fact, taking way too long to load pages for them. (Note, me and many others do not have this problem - only sometimes.)
So now I'm totally confused. Why do the same pages take longer for some, but not others?
Here are the results from users with fast load times and those with slow load times from the same page:
Main index page:
Fast: Page created in 0.768 seconds with 15 queries. Slow: Page created in 201.49 seconds with 14 queries.
Clicking "Show all unread posts since last visit"
Fast: Page created in 0.539 seconds with 14 queries. Slow: Page created in 298.94 seconds with 17 queries.
Clicking the "new" button to read the most recent post in a thread:
Fast: Page created in 0.253 seconds with 27 queries. Slow: Page created in 253.98 seconds with 19 queries.
I also have some users who occasionally can't load the site at all - "Server taking too long to respond" errors.
I found the thread on this forum with suggestions to make SMF faster - Twenty-four things you can do to make SMF go faster (Updated June 16th, 2010) http://www.simplemachines.org/community/index.php?topic=293441.msg1935333
I did not do any of the coding suggestions, as I lack the ability to do that. But I did everything else and it's still a problem. Here are my forum stats:
Running SMF 1.1.14 on a VPS server with 3GB of ram - hosted by a good hosting service. Running only 1 other SMF forum with minor mods - that forum is fast, no problems.
My forum is very small - 80 users averaging 100 posts per day.
DEFAULT theme only - users can only use the default theme. Mods installed - note, this problem occurs with and without mods:
Mod Name Version
SMF Staff Page 1.7
Drafts (for SMF 2.0 / SMF 1.1) 2.0.1
KeyCAPTCHA for SMF 2.0
Enhanced Profile 1.1.5
YouTube BBCode 2.6
Unread and Replies Tabs in Main Menu 2.0
Reply Button in All Posts 1.1
Country Flags 1.1.2
Global Headers Footers 2.0
AjaxChat Integration 3.2.1
SMF 1.1.14 Update 1.0
Users Online Today Mod 1.4.0
I perform all the maintenance tasks and back up weekly.
Can anyone help a lay-person like me figure out why my forum is slow for some, but not others?
Any insight or advice would be greatly appreciated.
Thank you in advance for your help.
