RE: 1 Machine with 4 GB RAM for Big Size MySQL Data Size
One word: Backups! If your potential client must restrict you to one server then your primary consideration in this design must be backups, this cannot be stressed enough. One server with 4GB main memory should be fine for your 24GB database with small monthly growth and low number of users, you should be fine using InnoDB with the default settings or perhaps some my.cnf tuning for your particular needs (look at the www.mysqlperformanceblog.com archives for some tips on that). But you absolutely must consider backups, if they already have a backup server then look at using the free version of zmanda or some other backup scripts. If not then you could consider using Amazon S3 as a backup solution, it's easy to use and quite cheap too.

MAC OS 10.6 Snow Leopard Breaks MySQL - Resolved
I tried creating a soft link to the /usr/local/bin/mysql but that didn't address the issues I was having. However, following a little more research I found a discussion of this problem at: http://stackoverflow.com/questions/1334272/cant-start-mysql-in-mac-os-10-6-s now-leopard which said: YOU MUST REINSTALL mySQL after upgrading to Snow Leopard and remove any previous versions as well as previous startup from the preference panel. install 86_64 10.5...I find the others did not work for me. Bummer. However, there was also a discussion suggesting the use of MacPorts: Have you considered installing MacPorts 1.8.0 (release candidate), and keeping MySQL up-to-date that way? That will build MySQL for the architecture and OS that you're using, rather than installing a 10.5 version on 10.6. I installed MacPorts http://www.macports.org/ (had to reboot) and ran the following commands: sudo port -v self update sudo port list sudo port install mysql5 The MacPort script reinstalled mysql 5 on my Mac and mysql came up properly apparently with everything where it belonged. Pretty slick and almost effortless.

Re: How to optimize a slow query?
How many rows were added to rmpdata1 table? If it is 13.4 million rows then it is going to take several minutes to join this many rows from the 2 tables. Is there a 1:1 relationship between the two tables or a 1:Many? If there is a 1:1 then I'd recommend joining the two tables into 1 table so you don't have to join them in the first place. The only other thing I can suggest is to change the type of index on the tables being joined to see if that makes a speed difference. For example, if you are using BTREE then switch to HASH or vice versa. See http://dev.mysql.com/doc/refman/5.0/en/create-index.html for more info.
