| | Hi, I am currently doing some DNN stress-testing to validate its scalability for a very large intranet site. The stress-testing tool we are using is pumping about 400 page requests per second at theDNN instance (we're running 4.5.3, on windows2003/sql server2005). When we tried the free version of pageblaster, we saw no improvement in the average page response time. Is this to be expected? I know with 4.4 the DNN folks added a lot of performance pieces, including the page compression, but I still thought, if I understand the concept of pageblaster properly, we would see some bump. We are using the DNN performance settings mentioned in another post here regarding ideal settings, and did follow the directions in the readme that came with the free version of the module. | | | |

| No, that is not normal. You should see about 10x improvement in Requests Per Second (RPS) after PageBlaster is added.
Are you getting cached pages in your PageBlaster cache folder?

| | Are you referring to the folder mapped in the PageBlaster config to cache-folder? We are using BroadcastPollingCachingProvider as the default provider because since we are running a webfarm when we used the FileBasedCachingProvider we were getting contention errors on the .resource files in the cache. Sorry, I should have mentioned this before. So does pageblaster only work if you use FileBasedCachingProvider? We don't get any files in the Portals\_default\Cache when we run with BroadcastPollingCachingProvider. | | | |

| Yes, I'm talking about the folder mapped in the PageBlaster config file.
Internal DNN caching using file based or broadcast polling doesn't affect PageBlaster.
You should see files with .pb.webinfo extensions in the PageBlaster cache-folder.
You can also check to see if PageBlaster is working by looking at the response header with a tool like Fiddler, or you can turn on PageBlaster tracing.
If you want, I can also take a look at your site. If you don't want to post a link here, then send me an e-mail directly. | | | |

| | thanks John. I've sent a trace file to your hotmail account (I didn't want to cog the post), and it looks like all the pages are being excluded from caching, so I don't see any .pb.webinfo files. | | | |

| I was just going through all my past support e-mails and realized that I never got this e-mail. Are you still not seeing the cache files?
One thing that it could be is if you are using an automatted tool it could be sending a Pragma request header that tells PageBlaster not to cache.
Try navigating around the site by just clicking with a browser to see if that produces any cache files.
If so, we may need to figure out why the tool is not allowing PageBlaster to cache. | | | |

| It looks like you have defined a UNC path for the cache-folder. That should work, but maybe you are missing the double slash in the front?
If you are using a UNC and can't get it to work, can you get it to work by mapping a drive to the share instead? | | | |

| | John...Could you please help us out with this as soon as you can? We have a Go/No-Go decision for pageblaster based on the test results.... | | | |
