File system access and speed

Are there any best practices as far as writing and reading text files to the file system?  In the simulators it works fine but when I test on an actual BB (currently a 8530 w/ v5.0.0.601) it seems like everything takes way longer.  Is there a speed difference between the store and the SDCard?  Does making multiple concurrent saves and/or reads compound performance issues?  

 

Thanks,

Re: File system access and speed

From what I understand saving to/from the SD Card is faster than "store".  "store" is a Java emulated file system on flash where the SD Card is a direct file system access.

 

I haven't seen multiple concurrent saves compounding performance issues unless there would be a lot of them. After a while there would be garbage collection that would have to be performed.
