Slow Search - mySQL optimized but still the same
 
1 Attachment(s)
I have a problem with some kind of commands with vBulletin. For example when you run a search the result page shows up after about 10 seconds (in this case the server load is almost at 0) and the creation time is something like "0.30~0.50seconds".

Another slow respond case is if you post a new thread, but not if you add a reply(!) or when you click on a link to the newes post of a thread "showthread.php?goto=newpost&t=5383" for example. This action takes about seconds again. But If you go to the same thread without this option it shows up instantly.

How can you explain this?

Are you using similiar threads functions? I'd disable them.

jyajay 10-16-2006 07:43 PM
No, this has no effect on my forum at all. I tested it with this function turned on and off.

Zachery 10-17-2006 12:12 AM
Did you disable them showing or disable them 100%? there are 3 settings that control them.

Originally I had this function turned off, after turning it on there was no extra slow-down. I assure you this has nothing to do with my problem.

Zachery 10-17-2006 09:40 AM
I assure you, you should try ;)

jyajay 10-17-2006 09:46 AM
I did, thats why I told you it really has nothing to do with it.

What are the 3 settings that control them?

Thanks.

AdminCP -> Messag Searching Options -> Automatic Similar Thread Search
AdminCP -> Thread Display Options (showthread) -> Show Similar Threads?

I just found two settings that have a direct control over that. Anyway I enabled these after i noticed my problem, still no change at site creation tme.

backup your old my.cnf and replace it with this one.

Code:

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
skip-locking
skip-innodb
query_cache_limit=8M
query_cache_size=256M
query_cache_type=1
max_connections=500
max_user_connections= 300
interactive_timeout=20
wait_timeout=20
connect_timeout=6
thread_cache_size=128
key_buffer=16M
join_buffer=1M
max_allowed_packet=16M
table_cache=1024
record_buffer=1M
sort_buffer_size=2M
read_buffer_size=2M
max_connect_errors=10
# Try number of CPU's*2 for thread_concurrency
thread_concurrency=4
myisam_sort_buffer_size=64M
#log-bin
server-id=1

[mysql.server]
user=mysql
basedir=/var/lib

[safe_mysqld]
err-log=/var/log/mysqld.log
pid-file=/var/lib/mysql/mysql.pid
open_files_limit=8192

[mysqldump]
quick
max_allowed_packet=16M

[mysql]
no-auto-rehash
#safe-updates

[isamchk]
key_buffer=32M
sort_buffer=32M
read_buffer=16M
write_buffer=16M

[myisamchk]
key_buffer=32M
sort_buffer=32M
read_buffer=16M
write_buffer=16M
Then restart MySQL. Also what version of MySQL and PHP are you running.
