[cfaussie] Re: Lots of calls to DirectoryExists()
I think it was Sean too, however it would not just be Sean. One of things we as developers tend to ignore, well maybe not ignore. But we do try to emphasise to much on getting it right the first time, the pressure from clients to do this is let's say a big factor in the equation. However it may never become a problem, and may scale very well. But as Barry has indicated, one can always revisit and refactor if it ever does becomes a problem.

I think it was Sean Corfield (could be wrong) that used to sprout a particular wisdom along the lines of developing for maintainance and reuse not performance you can always refactor for performance later and if you built it with maintainability in mind, refactoring should be pretty straightforward and painless On Wed, Oct 29, 2008 at 10:26 AM, Joel Chia <[EMAIL PROTECTED]> wrote: > I've gone off and used DirectoryExists() and it seems to be holding up fine. > So I guess I was worrying for nothing :P > > Cheers, > -Joel > > > From: cfaussie@googlegroups.com [mailto:[EMAIL PROTECTED] On Behalf > Of Simon Haddon > Sent: Wednesday, 22 October 2008 6:17 AM > To: cfaussie@googlegroups.com > Subject: [cfaussie] Re: Lots of calls to DirectoryExists() > > File system access to see if a file or directory exists is fast.

I've gone off and used DirectoryExists() and it seems to be holding up fine. So I guess I was worrying for nothing :P Cheers, -Joel From: cfaussie@googlegroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Simon Haddon Sent: Wednesday, 22 October 2008 6:17 AM To: cfaussie@googlegroups.com Subject: [cfaussie] Re: Lots of calls to DirectoryExists() File system access to see if a file or directory exists is fast.

File system access to see if a file or directory exists is fast. Can't imagine it causing a problem any more than, say, a small loop. Easier than a database query.

[cfaussie] Re: Lots of calls to DirectoryExists()
Is there a performance issue ? don't prematurely optimise unless you have to:) how does your app perform with your max expected number of users and directories being checked? file systems are pretty fast these days. jmeter is pretty easy to setup to test this kinda load, there's a quick guide on my blog if your intersted On Tue, Oct 21, 2008 at 2:54 PM, Joel Chia <[EMAIL PROTECTED]> wrote: > Hi, > > I'm just working on a page here that's ment to display a link if a certain > directory already exists on the server.

[cfaussie] Re: Lots of calls to DirectoryExists()
I think it wouldn't be too bad, but there might be smarter ways. What about recursively browse the directory once and build a struct, then you can use if structKey exists Regards Dale Fraser From: cfaussie@googlegroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Joel Chia Sent: Tuesday, 21 October 2008 2:54 PM To: cfaussie@googlegroups.com Subject: [cfaussie] Lots of calls to DirectoryExists() Hi, I'm just working on a page here that's ment to display a link if a certain directory already exists on the server.
