Many a time, ColdFusion application code is deployed on a network path when your
ColdFusion deployments are of large-scale and mandated to use network paths.
After setting up the server for the first time, if there is any performance hit, as the first thing you would want to cross-check few things. One of the things to determine is if there is any network latency.
Though you would have got same network within your organization same as earlier, your OS version also would have changed.
Follow the steps below to see if the performance hit is due to network latency-
When the server is under moderate or full load(with at least 8-10 requests under process), take 2 or 3 thread dumps with 30 seconds interval.
It is not appropriate to take thread dump when the server has negligible load and anlyze that as there may not be any in-process requests.
If you are not sure how to take thread dump, you can simply follow the following blog.
Open the thread dump file:
Under moderate or full load server conditions, if you see more than 5-8% of running ColdFusion threads containing “WinNTFileSystem” in the thread’s stack trace --> It means that there is lot of time being spent in trying to resolve the application file paths.
(Note: ColdFusion threads can be identified by the name starting with "ajp-bio-" )
For Example, if there are 50 threads with thread name starting "ajp-bio-" in the thread dump, if you see WinNTFileSystem in more than 2-3 threads, it is the time you start looking at minimizing the network latency.
Once you know there is latency, you would want to know how much is the latency when compared to the application existing locally.
Created a very basic network latency test program to validate this.
You can take the jar from here.
And run it from command prompt as follows:
> C:\ColdFusion11\jre\bin\java -jar <Path of NetworkPathsTest.jar> <Network or Local Directory Path >
If the network path (Ex:- \\orgserver\d$) is accessible only to the ColdFusion service user, open command prompt as that user ( runas /user:<cfserviceaccount domainname>\cfserviceusername CMD )
Path Arguments can be one or more. More Path arguments is a good measure to see the difference clearly.
C:\ColdFusion11\jre\bin\java -jar C:\ColdFusion11\NetworkPathTest.jar \\orgserver\d$\deploy\cfm\
C:\ColdFusion11\jre\bin\java -jar C:\ColdFusion11\NetworkPathTest.jar \\orgserver\d$\deploy\cfm\ \\orgserver\d$\deploy\cfm\api\
Try the same paths keeping the content same on the local machine and see the time differences.
For the same paths on local and remote, the difference in time should not be exponential.
These tests are to be performed on your ColdFusion server machine.
Once you have validations and found any latencies, it is the time to call for network optimization expertise.
This post is to announce the release of new updates for ColdFusion 11 and ColdFusion 10.

You might remember the Adobe Panel discussion from last year's ColdFusion Summit?
We're going to have it again this year, so please be sure to stop in for the discussion. The format will be slightly different this year, in that we're opening it up to audience questions from the begining. Last year we didn't get a chance to finish all of the audience questions so I'm looking to do it differently this year. Come with your questions for Adobe and topics that the community would be interested in hearing about.
This year we have a great panel, you may know some of these community members already!

Introducing the Adobe ColdFusion Summit 2015 app.
The hands on labs for the preconference are now sold out! These are going to be great additional learning experiences for those of you who were able to get in.
I blogged about the workshops here:
There will be a VM download for the labs to be sent out via email to those of you who registered. Please check on the specific requirements ahead of time so that you come prepared and aren't missing any of the content because of setup.
We're looking forward to meeting all of you at the conference!
