Re: DB speed

For SIMPLE SIMPLE selects and inserts, MySQL will probably remain faster. If you are doing a very simple web set up where you are mostly inserting and spitting out single table information, MySQL will be the way to go. Anything else, I would recommend PostgreSQL. It's got FAR superior features and anytime you start very complex queries ( like JOINS and multi-table aggregate functions, etc ) postgres will blow MySQL out of the water. They are both nice, just for different purposes. MySQL = simple, PostgreSQL = anything else. Also, you can run "EXPLAIN <query>" on PostgreSQL to find out exactly what is happening when you do a query and if it's using an index properly or not. regards, dan tuxen wrote:

I think i read something a while ago, about mysql being faster, having less features, but postgres being a little slower but able to handle LARGE databases better than mysql. I could be wrong, so dont take my word for it. At the end of the day they are both good db's. On Thu, 2002-10-10 at 09:02, Simon Taylor wrote:

Well obviously - cos MySQL rocks!!, but seriously I also did some tests and got variable results from different db's - even got an odbc connection to access to run faster than mysql at one stage!! - something tells me there are other factors contributing..

I'm making some testing over DB.php (PEAR) And i wan't to know if this is normal. I've made some script where I connect do SQL server and execute one simple (1row) query. I use pgsql and mysql. tables and indexes are same for both servers. So test table is identical Whe i execute those script i get some timing results PGSQL Total time: 0.0576 Execution time: 0.0185 MySQL Total time: 0.0086 Execution time: 0.0028 Time is in seconds. My machine is PIII 333 MHz with 128MB RAM. I table is only 3 rows of data. I want to know why is sucsh diference. Both servers runing with socket connections and using connnect (non-persistant) -- tia,
