Re: cffile read 47 MB
Provided with a disclaimer, as I asked a Java friend about this and he suggested something called Stax api for xml parsing. I did some quick research and found this article. It would be more Java than CF, but hey CF plays nice with that. http://www.javacodegeeks.com/2013/05/parsing-xml-using-dom-sax-and-stax-parser-in-java.html Based on that, I would imagine, CF uses a Dom parser based on its parsing performance. All a bit dependent on the required outcome however as this may be overkill if you just need to read the file. Are you parsing and searching xml, or just doing some file manipulation stuff?

Re: cffile read 47 MB
use the FileRead function. it can handle large files and doesn't suck up all the resources. forget trying to use CFFILE for large files. http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=functions_e-g_13.html On Mon, Dec 9, 2013 at 2:30 PM, Russ Michaels wrote: > > On 32bit you can only use around 1gb, it will fail to start if you assign > too much. > > Russ Michaels > www.michaels.me.uk > cfmldeveloper.com > cflive.net > cfsearch.com > On 9 Dec 2013 22:25, "John M Bliss" wrote: > > > > > And for 32 bit? > > On Dec 9, 2013 5:14 PM, "Steve 'Cutter' Blades" < > > cold.fus...@cutterscrossing.com> wrote: > > > > > > > > Looks like you're still using the default install values.

Re: cffile read 47 MB
Switch to 64-bit. :-) (Seriously. There's not much hope for memory-intensive operations on a 32-bit machine. You're limited to only being able to utilize something like 3.4GB of RAM, and that just ain't gonna cut it.)

Re: cffile read 47 MB
On 32bit you can only use around 1gb, it will fail to start if you assign too much.

Re: cffile read 47 MB
Looks like you're still using the default install values. On a 64-bit system, I generally look at my overall RAM available, subtract 2GB for the OS, then adjust my CF RAM availability according to what's left, starting at 1 GB max, 256 min, then gradually move up half a gig as required. Finding the right balance in your JVM config (min, max, gc, etc) can really help tweak the performance of your application.

Does this behavior seem odd? Are you just doing a CFFILE read? Or are you also converting it into an XML object? Because that will increase the internal memory size needed by quite a bit. But yes, you can probably fix this by allocating more memory to the JVM. Nowadays, if you're running a 64-bit version of CF, you can throw a lot of memory at it and avoid these types of problems most of the time.

cffile read 47 MB
Hi, I'm attempting to perform a cffile read on a 47 MB XML file. It's failing but ACF10 is not throwing an error to the browser. Finally dug into the logs and am seeing "Java heap space" errors. My JVM is configured as such: Min JVM Heap Size - 256 Max JVM Heap Size - 512 JVM Arguments - -XX:MaxPermSize=192m Solution is just to increase those numbers?
