Profiler Example : Read - Delete - Create a new file and add a new lines

The Read_Delete_Create_Write\Example.cfm script is a similar to the Read_Create_Write_Example.cfm from this example. However, with the difference that a file is deleted after has been read.


        <title> This is a read/write example of ColdFusion process </title>
        <cffile action="read" file="/opt/applicationservers/coldfusion/11.0/cfusion/wwwroot/Test/myFile2.txt" variable="Message">
        <p>Delete the old file </p>
        <cffile action="delete" file="/opt/applicationservers/coldfusion/11.0/cfusion/wwwroot/Test/myFile2.txt">
        <p> Add a new line to the new file </p>
        <cffile action="write" file="/opt/applicationservers/coldfusion/11.0/cfusion/wwwroot/Test/myFile3.txt" output="new line">
        <cfloop from="1" to="200000" index="i">
            <cfset s = gettickcount()>
            <cffile action="append" file="/opt/applicationservers/coldfusion/11.0/cfusion/wwwroot/Test/myFile3.txt" output="Did you add something_New?">
            This is the execution time: #s#
        <h2> This is the end of the loop.</h2>

Profiler Results

When the script has been executed, we will be able to find the transaction in the Profiled Thread History tab. ( See screenshot below )

Lets take a better look of the transaction. ( See screenshot below )

By looking the screenshot above, we are able to see a number of differences in performance between the this example and this example

In this example, the method has consumed the 73.4% of the total execution time, while the method has consumed 46.7% of the total execution time. Moreover, a specific percent of time was used for the deletion of the file. So, comparing the two examples provided, we notice a number of changes related to the consumption of time.
