Hard to give details on performance optimization without knowing more about the details for your load, but there are a number of cache-related parameters (query cache, key cache and so on) that could be increased to take optimum advantage of the additional RAM.

Re: best mysql optimization tutorial and/or quick start guide?
Configuring and optimising a MySQL server is highly dependent on your usage of it. The most important question for you now is probably: which storage engines do you use? Based on that, you should start configuring MySQL to assign memory to optimise the usage of each as good as possible. Have fun!

Hi All, I'm not sure if this question is fine, I'm new to the list and I just have one very important question. Can anyone help me suggest the right optimization for our company's server. Our current server is a Dell PowerEdge 1900 a QuadCore with 1TB total (Raid 1) of HD space and 4G RAM. The company is 300 seater callcenter with around 2000 Transactions (inserts/updates internally and externally) per day. Any help would be much appreciated. Here is our current mysql config file.

mysql optimization
i am looking for mysql 5.0 optimization documents on FreeBSD 6.3-stable. I tried to install "mytop" to see the running style of the system but p5-DBD-mysql has been failed coz of many bugs. And also read this section http://dev.mysql.com/doc/refman/5.0/en/mysql-benchmarks.html . do you have any advice for me to make better the performance of mysql on my bsd box. People says that: mysql is much more better on linux boxes then bsd boxes. Coz of linux threads style. My bsd box has linux compatibility. linux_base-fc-4_13 Base set of packages needed in Linux mode (for i386/amd64) linuxthreads-2.2.3_23 POSIX pthreads implementation using rfork to generate kerne is it true? Or can i say that no you r wrong.!! Thanks for your help...
Re: MySQL Optimization error ?
This isn't a bug, it's a missing feature. The parent query won't use indexes, just the subquery. There's been a lot of complaints about how it renders sub queries less than useful. I seem to remember that it might be fixed in 5.1, but I'm not a reliable source of info on this.

Re: MySQL optimization
Hi, It seems that you don't have any index on your tables. You should at least create an index on flObjectID in all tables. You should also use 'explain' on your query to make sure that indexes are properly used.
