Problem Description: 

Upload small file (10Mo) or large file (100Mo) from Coldfusion 9 or 10 on Windows 2003 Server into a network directory is Ok (<cffile action="UPLOAD" filefield="file" destination="\\192.168.0.X\myNetworkDirectory\" nameconflict="MAKEUNIQUE">)

Upload small file (10Mo) from Coldfusion 10 on Windows 2012 R2 server into a network directory is Ok but with the same server and same destination directory and a large file (100Mo)  returns an error after a long time. Coldfusion succeed in copying the file but after a long long time... too long to return a correct answer.

With the same server an the same file a local CFFILE UPLOAD and  then a CFFILE MOVE is OK.
<cffile action="UPLOAD" filefield="file" destination="C:\tempUpload\" nameconflict="MAKEUNIQUE"> 
<cffile action="move" destination="\\192.168.0.X\myNetworkDirectory\myfile" source="C:\tempUpload\myfile">

Comments:

When file is directly uploaded to destination it inherits the permissions of destination. When we move a file from say temp dir to destination file retains its permissions. So there is a difference between the two operations. Move internally renames the file and is faster than file copy which happens when file is directly uploaded. Since uploaded file should inherit permissions of destination directory we cannot replace this operation with file move for performance. Although we have improved the performance for file copy and it should be roughly 30 % faster. This will make upload to network drive faster than what it already is but won't match moving file from temp location. (Comment added from ex-user id:sandeepp)

Unable to reproduce the slow file upload issue to network share. The following code only took 28 seconds to transfer a 200MB file between 2 Windows 2012 R2 servers: <cfif FORM.keyExists("submit")> <cfoutput>#now()#</cfoutput> <cffile action="upload" filefield="filedata" destination="\\1.2.3.4\myshare\" nameconflict="overwrite"> <cfoutput>#now()#</cfoutput> </cfif> <form method="post" enctype="multipart/form-data"> <input type="file" name="filedata"> <input type="submit" name="submit" value="submit"> </form> Thanks!, -Aaron
