ColdFusion 8 Application Server offers an important improvement regarding memory utilization during the uploading of large files via the CFFILE tag. This entry will offer an experimental observation to demonstrate the improvement in CF 8, but first I'll expand upon each of the related settings and provide some usage scenarios.

Request Throttle Settings
The ColdFusion 7.01 Administrator introduced new file upload settings to better control file uploads. The broadest setting is called Request Throttle Memory, with a default of 200MB, where its purpose is to regulate the cumulative impact of all concurrent large file uploads on the ColdFusion server. The adjacent setting for Request Throttle Threshold, default of 4MB, is the minimum size of file uploads for which the throttle should regulate, anything below the threshold is ignored by the throttle. Further up on the Settings page is also the new field Maximum Size of Post Data, with a default of 100MB.
