Hi guys,
Since I installed CPG145, the CPU load on my dual xeon 2.8 ghz, 2gb ram webserver went from an average 5-10% to a 40-50% CPU load and beyond.
Is this CPU load normal?
What is causing this CPU load?
Is there a solution?
Thanks in advance and regards,
Robert-Jan

My CPG website has 2,100 unique visitors a day who produce about 50,000 pageviews. The website transfers about 18 GB a day in traffic.
I use the "Modded by Stramm" modpack and ALL statistics and logging is disabled.
The same webserver also runs my other websites, which use php/mysql scripting as well. Those websites get about 85,000 unique visitors a day. And that only gives 5-10% CPU load. This "little" 2,100-uniques-a-day CPG site caused may load to multiply by 5.
When giving the "top" command on the UNIX root, I see that the load is caused by apache2. Sometimes I see 3-4 apache2 processes running simultaniously, who demand 12% CPU load each.
Thanks in advance and regards,
Robert-Jan

link?

Continuously? That processes with 10+% CPU may occur if a user uploads files (depending on your OS, overall load even more)
-
Yes, I am continiously having 50%+ CPU load. Even when nobody is uploading pictures, I still have several apache processes with 12-20% CPU load each. (The "top" command refreshes, sometimes it's just one, next refresh might be 5 processes).
I even see peaks of 75% CPU load...

enable debug for admin to find out what queries need the most time/ cpu
-
Since I cannot post long messages on this board (hitting "post" button causes script to hang), here's the debug output: http://www.ishotmyself.nl/error.html
-
disable displaying of comments count below the thumbs, each count needs a query -> 15 thumbs per page, 15 extra queries
I guess you've private albums enabled?? That may suck a lot of CPU as well
You need a lot of queries displaying a thumb page. Reduce that...
compare to my site. I've enabled debug
http://stramm.st.funpic.org/thumbnails.php?album=8
that's 35 queries. If I disable displaying comments count -> 23 queries.
I have additional user info enabled (pm and buddy list info) -> disabling it -4 queries
I have the plugin system enabled -> disabling it -1 query for the system and -2 queries for the online plugin
If you do not use login / and or banning system you can disable it (modifying code) -> -2 queries
If I'd optimize max I'd have 14 queries (it's not the same for each install, also depends on the number of albums/ cats etc) compared to your 62
But that seems to be a nice box ;)
Page generated in 0.399 seconds - 62 queries in 0.005 seconds
-
OK, I'm going to try reducing queries...
Those other messages, about undefined variables, does that need work?
Thanks a lot so far!
Regards, Robert-Jan
P.S. Are you (or any of the other wizards) available for paid customization of CPG?
-
I already had private albums disabled.
Thumbnail page original config:
Page generated in 0.389 seconds - 43 queries in 0.004 seconds
Disabled "x comments" and "viewed x times" below thumbs:
Page generated in 0.42 seconds - 18 queries in 0.008 seconds
Reduced # of queries by 60%, hopefully this helps :)
-
BTW, homepage gives 42 queries, intermediate pic 22 queries. Any room for optimization there?
I'm still curious if you (or one of the other wizards) is available for paid custimization of CPG...

Start a new thread in Looking for Freelancers / Paid help (http://forum.coppermine-gallery.net/index.php?board=30.0) board. Do read sub-board rules, read first! (http://forum.coppermine-gallery.net/index.php?topic=8170.0).
-
I've reduced the number of queries, but I have ZERO results. CPU load is still 40-50% and up... And I still have multiple apache 2 processes running at the same time, demanding 10-20% CPU load each.
Any ideas where to look?
Thanks and regards,
Robert-Jan

get rid of the last additions meta album or reduce the number of rows if that's an option for you.
-
You could probably try installing a php cache like eAccellerator or turning on query caching in mysql, while disabling ratings and hit counting for cpg.
I used to have server loads as high as you, but doing both of those things brought the beast under control.

Hi,
I'm getting 80%-95% CPU load with Coppermine Gallery 1.4.8 (the same with lower versions) and slow page load:
Page generated in 4.881 seconds - 27 queries in 0.127 seconds - Album set : ; Meta set:
My web server gets a load of ~2000visits/day and ~60.000 pages/day
CPG gallery here (http://www.pozehaioase.ro)
Hardware stuff:
DELL - Intel PIII 933 Mhz, 500 RAM, HDD maxtor 80Gb, 3COM networking, optical fiber broadband WAN.
Soft:
WinXP SP2, latest XAMPP (apache, php & mysql)
Tuning server:
WinXP: disabled every services not needed (indexing services, restore, wireless ... etc)
apache - memcache on, info&status off, deflate on, hostlookup off ..etc
mysql - cache query, cache threads .. etc (myhuge.ini)
php - zend accelerator level 15
As I've seen, the apache & mysql works great with minimum CPU load when serving static html pages (less then 0.003sec even on a high load)
The problem seems to be on the PHP(cpg) side
Any other clue?

Are you using lang fallback? If so try disabling it.
-
I use the
- default english language file (modified by myself for the romanian visitors),
- no fallback for language
- no language flags
- no change theme option for the users
- no language selection option for the users
- the classic theme
- no extra scripts (except users online - a small one)
- I've even deleted the sort thumbnail option in album view,
- Plugins disabled
- No pic rating for the unregistered visitors
- BB code disabled
- no simles in comments
- no loging
- no stats
- no categories, only 12 albums
- all the pics are progressive jpeg enhanced
... so, it's a spartan configuration still high CPU load 85-95% with only 50-maximum 70 users online

1. provide a link to your 1.4.8 gallery (with debug for everyone enable)
2. upgrade your 1.4.6
3. please do not remove copyright

1. provide a link to your 1.4.8 gallery (with debug for everyone enable)
2. upgrade your 1.4.6
3. please do not remove copyright
1. http://www.pozehaioase.ro
2. gallery is up to date (manually pached)
3. copyright was never removed (pls see google cache)
-
1.gallery on that link is 1.4.6(stable)
try yourself :
- http://www.pozehaioase.ro/sql/basic.sql
- also there is a version stamp at the end of each page (view source)
2.I can't see the copyright , it's hiding under table check this
-
I have installed "a la carte" the last CPG version 1.4.8
And, as i thought, still the same high CPU load.
-
1.Copyright is invisible !!!
2.Everything seems normal with CPG (this is normal ,Page generated in 3.571 seconds - 24 queries in 0.12 seconds)
I think you should check other stuff
-
I'm thinking hardware upgrade.
PHP is so much CPU intenssive even with Zend Optimizer enabled.
-
due to the numerous questions related to slow servers running CPG I'm asking the moderators if it's ok to start a new topic dealing with Apache/Mysql/PHP tuning for CPG
If you'll aprove my request, I'll start a topic with samples of apache config, php.ini & my.ini for you all to see, comment & tune :)
-
you are most welcome to share your experience

Hi again
Having successfully installed Coppermine, I decided to start reading the included document (Documentation and Manual) in Internet Explorer. Straightaway, the CPU useage goes up to at least 50% and stays there. It actually makes reading the document impossible as it takes ages "to catch up to your mouse clicks". It only appears to be an HTML document, so I'm wondering exactly what it contains to slow things down so much.
For example, while writing this note, my CPU useage was about 1-2% which is pretty normal.
Does anyone else have this problem?
Regards
Terry

Your reply is totally unrelated to this thread. This thread is about resources consumption on the server, not on the client. We can not support your client issues.
