PM's are 75+ Queries?!

I'm speeding up my server, and was cross referencing executed queries per unique page @ total users to the server load, and found that in most instances (Index, Forum View, Topic View, Downloads (Index, Category, File) View, Members) the executed query count has a highest value of 20 (at least on my installation).

Now, I understand that the # changes for each forum/topic, etc. but 95% of the time, nothing goes above 20 queries, except private conversations viewing goes above a whopping 70.


Is there any way that it can be loaded with less queries?

just looked at this and you seem right, looking at the queries it seems to run this query again and again:

SELECT * FROM ibf_skin_cache WHERE cache_set_id=1 AND cache_value_1='skin_1'

looks like some of the code needs to be refactored as it seems to be caught in a loop somewhere. 75 queries is alot on any server even if they are cached. It should probably be looked into.

Thanks for confirming this, makes me feel better knowing that a Community Dev has "confirmed" the issue. :)

Whilst you're right that it should be looked into (and I'm sure it will be), it's a little naive to make judgements about what is a lot for "any server", without any knowledge or context.

Our database servers regularly handle well over 1,000 queries a second each, without even a hint of struggling. :)

maybe but i've never in my entire programming life had a page that runs 75 db queries (cept for db updating scripts/cronjobs, but speaking pages accesible by webserver). The thought of having that many just gives me chills and would keep me up at night.

to put that into context if you website had about 100 users online all running 75 queries each = 7500, i think for any webserver thats quite a few. Might not bring it down but enough to make you worry. (oh ipb has summit like 600 online atm).
