asp_databases thread: How many users at a time access accepts


Message #1 by "Ivan" <ivanv@w...> on Thu, 22 Mar 2001 09:42:43
can someone tell me how many users at a time Ms Access accepts.  I have 

heard 255 but in reality is this real, or at-least in ASP.  



Is ms Fox-Pro better than access for web development?



Thanks

In reality it is not real. It is more likely access can support about 64

connections, but performance is known to start to deteriorate at around 30

or so users.



Keep in mind this is concurrent users. So for performance to dwindle you

would need 30 or more users to be running a query against your database at

the same exact time. You could have 300 people at your site, but chances are

30 or more would not be hitting your db at the same time.



Access has problems because it is a single-threaded-apartment. There is a

good article comparing Access to SQL Server on Charles Carroll's

www.learnasp.com site. The article can be found at:

http://www.learnasp.com/learn/accessSQLserver.asp



At the bottom of the article there is a script that will show you how many

concurrent connections your access db can support. It usually starts to

create errors at about 64 connections.



Hope this helps.

Scott

If you using Access as the back-end for you website... 10 (and maybe 20) 

is about the max... performance REALLY suffers when you get up around 10 

and goes downhill from there...



I believe FoxPro has a bit higher limit, but if you gonna have serious 

traffic to the site, IMHO, then go for SQL (in whatever flavor you 

prefer ... Oracle, mySQL, etc.)
