and lot more...

these type of queries are causing lot of cpu throttling and slowing down site loading.
any one facing this type of issue or any guide pleas?

See http://documentation.coppermine-gallery.net/en/performance.htm

Those queries would probably run faster if you stopped using album keywords.

[aftab1003]

thanks Nibbler for your kind reply...
some of my albums was with keywords and i removed them.

but now with another slow queries are coming like this..

# Tue Mar 22 14:14:03 2011
# Query_time: 2.321036  Lock_time: 0.000119 Rows_sent: 0  Rows_examined: 1
use eshoppin_cpg;
UPDATE cpg14x_pictures SET hits = hits + 1, lasthit_ip = '119.73.33.71', mtime = CURRENT_TIMESTAMP WHERE pid = 290

can you pleas suggest me what thing making this slow query?

Go to: Config >> Logging and statistics

then try turning down / off some of what you have set for logging and stats.....

turning down / off some of what you have set for logging and stats.....

Regarding the query

UPDATE cpg14x_pictures SET hits = hits + 1

you should try to turn off the 'Count file views' option.


Imo your server has a very poor performance if it takes so long to update a single row. Do you get that slow query continuously or just once?

[aftab1003]

Thank you Thank you .....
First i love the Support and then CPG software.

at this time, i am logging "ALL logging mode", logging Ecards, Count File Views and Album Views.

Regarding the query you should try to turn off the 'Count file views' option.

File Count Views is now TURNED OFF.

use eshoppin_cpg;
UPDATE cpg14x_pictures SET hits = hits + 1, lasthit_ip = '218.248.64.139', mtime = CURRENT_TIMESTAMP WHERE pid = 212

Go to: Config >> Logging and statistics

then try turning down / off some of what you have set for logging and stats.....

Logging is now turned off.

lets see whats next. and i will let you know if there is any problem after doing your suggestions.

i have moved my sites from this server to another, but no effect. any guide pleas?

[Αndré]

Imo your server has a very poor performance if it takes so long to

... execute such simple queries. That may also apply to your new server. Similar queries on my simple development machine with ~80000 rows in the table I'm querying takes only

0.0005 sec

or

0.0003 sec

query times.

Hi, I have a similar problem with queries slowing down all the website (22 000 photos, 96 000 comments, 969 albums). I think that problem could be in having too much keywords in database (hudreds, maybe thousands). I disabled album keywords here http://documentation.coppermine-gallery.net/en/configuration.htm#admin_allow_user_album_keyword  but did not help. All the keywords are still in db and users can assign keywords when uploading files. Shall I delete the keyword list and leave there only a few keywords to use? Is there any other way how to optimize keywords or any other feature to fasten server load?  Thank you.
I am running CPG in test directory without pictures here http://www.fotoradce.cz/galerie4/index.php

1) Please start a new thread for your own issue. (The admins can decide to split your post.)

2) Your site response was inconsistent when I tried it at different times, so therefore...

3) Turn on debug, check your server logs for errors that could have caused a slow response.

4) Post a test user account with user name and password if you have a password protected gallery.
