Group,
I have been working with Mysql for about 5 years - mainly in LAMP shops. The
tables have been between 20-100 thousand records size. Now I have a project
where the tables are in the millions of records.
This is very new to me and I am noticing that my queries are really
slowwwwww!
What are the options that I have to speed my queries on the mysql side with
regards to the my.cnf file. I have a fair understanding of
sql optimization and I understand explain. I just want to see if
there is something that I can do with the server also.
Thanks to all.

print @c=map chr $_+100,(6,17,15 ,16,-68,-3,10,11,16,4,1, 14,-68,12,1,14,8,

Hi,
I'm somewhat new to MySql. I've been using it for a while, but pretty much
out of the box setup, and am starting to suffer heavily with my larger
tables. I have a table with 5,000,000+ rows that I have to search and do
joins on. Although I have an index set up for it, the joined select will
still take some 400+ seconds to return, which is obviously unacceptable.
This is due to enormous HD access.
Perhaps someone can help me...

I REALLY dont want to switch to oracle :( but I cant get these tables
working any faster.
I've got 2 dedicated servers, each with a slave, all run 32gig 15k rpm
raid 5 on u320 perc raid cards, dell 2600/4600's with single channel
backplanes (new ones will have dual channel)
All have 2 gig of ram, but I've never seen mysql use more than 300mb
of ram.

Hello,
I have a client (customer) who asked the question : "Why would I buy and
use UDB, when MySql is free?"
I had to say I was stunned. I have no experience with MySql, so I was
left sort of stammering and sputtering, and managed to pull out something
I heard a couple of years back - that there was no real transaction
safety in MySql. In flight transactions could be lost.

Hi there
I've noticed some very weird things happening with my current MySQL setup
on my XP Laptop, a development machine.
For a while, I have been trying to get the MySQL cache to work. Despite
entering the required lines to "my.ini" (the new my.cnf) through notepad
AND MySQL Administrator, the cache does not work.
So, today I took a peek at the 'Health' tab in MySQL Administrator.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
