How much data can MySQL push out?
We are experiencing some issues with performance on a non-MySQL box and are looking for alternatives (and alternative methods). Once of the issues that we seem to be facing, is that the pure volume of data which needs to be pushed out. The other database is pushing out (at peak) 12.5 megabytes per second and is being hit with 30-45 queries per second. If we rework the application, we end up with one of two solutions: 1) move to MySQL for the database engine (it currently is MSSQL) 2) Rework the application, so that the application still talked to MSSQL, but we generate static pages (this is for a website) and store them in MySQL, which are then served. This will reduce both bandwidth and queries per second. Bandwidth is unknown, but the queries per second are estimated at 15-25 queries per second. The select statements would be very generic though (select * from table where ID='abc123') This leaves one major question. How much data can MySQL push out? Can MySQL handle 12.5 megabytes (not megabits) per second of data? Will MySQL handle 20 queries per second? I know a lot of this also determined by OS/hardware. MySQL would be running on a 2-CPU Sun box. Any information with regards to this would be of use. If anyone also has such information on MSSQL (what is the Application Limit of MSSQL) it would also be helpful. thanks benji --- Ben Spencer Web Support [EMAIL PROTECTED] x 2288 - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: How much data can MySQL push out?
Sorry, I do not have much experience with MySQL on Suns (at least not in pushing it to the limits). On an Athlon 700Mhz selecting 1 random rows out of 6, I get over 330MB/sec (1000 queries/sec) on localhost and about 5.5MB/sec via a 100MBit TCP connection using the mysql command line client like this: this helps A LOT. MySQL doesn't have to be on the Sun Box. What OS where you using? We could put MySQL on a Windows box. I don't know that I could convince them to put it on a Linux box though. --- Ben Spencer Web Support [EMAIL PROTECTED] x 2288 - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: How much data can MySQL push out?
They've been using Replication for a long time at Slashdot. Really? If I were to go by their Alexa traffic rating of 1390, I'd think it would not even be necessary. Our traffic ranking is 859 and we don't need to do anything like that. Maybe Alexa is not a good measure. :( I like our ranking there... I'll check what our bandwidth utilization is. We don't have a problem yet.

data modeling question
Hello all, I have an 'items' table with 2 'types' of items -- 'foo' 'bar' Say that items of type 'bar' may be further classified as 'subtypes' 'baz', 'quux', etc. Now I build an online store so that visitors may buy items. Contstraints 1.) I would like to, as much as possible, use the same code for ordering 'foo'-items and 'bar'-items. 2.) If a user orders a 'bar'-item, they MUST specify a subtype. I.e. -- one may buy a 'bar-baz', or a 'bar-quux', but NEVER a 'bar'. My questions are these: 1.) Does it make more more sense to split the 'items' table into a 'foos' table and a 'bars' table? This means I will often have to recombine them using more than one query: select * from foos where foos.id in (shoppingcart) + select * from bars where bars.id in (shoppingcart) 2.) If I DON'T split into 2 tables, I must then keep the '#inStock' in both the 'items' table (for 'foo'-items) and in the 'subtypes' table (for 'bar'-items). This doesn't feel right. Any suggestions?

RE: Multiple MySQL Instances...
Hello Matt You probably already thought of this - but why not just set up a database or table for each department and set up separate users with privileges to their corresponding database or table? It would virtually accomplish the same thing. They would have their own database that could only be accessed by them and couldn't be squashed (or even accessed) by other departments. Just a thought! jeff -- Hey All, On Redhat Linux is there an easy way to have an ISP style setup where each user has their own database directory? Long story short, we have to implement a small in house server that will allow multiple departments to create their own little web pages. Perhaps I've missed something on MySQL.com and I know I've looked high and low on Google and haven't been able to find anything that matches. We're trying to avoid each of the departments squashing the other's data somehow and thought this would be the best way if it's possible? I'm looking for any pointers or How-To's or just a simple You missed section X in the documentation... Thanks in advance!
