Hi,
We are using the latest version of ASPNETZERO and have created a website using the framework. The site takes more than 25seconds to load the login screen. Below is the performance graph and also the network traffic. We have not customized the login screen and using the default template.
This is very concerning, our application's performance needs to be almost instant. Please let me know what we should do to optimize the performance.

Hi @sumitshah
Could you tell, how did you publish your Angular app ? As I can see, your main bundle is about 4.4 mb and it is a bit high.

Hi,
Thank you for the quick response.
Below are the steps, how we are deploying the website:
- We are publishing the web.host project(from visual studio 2017 professional edition)
- Similarly, we are using 'ng build --prod' command to publish the angular project
- Then zipping the files and sending it to the webserver
- On the webserver we are deploying the client and server as single website(by setting up localhost in the appsettings.production.json file)
- Below is the snippet of the config file:
{ "ConnectionStrings": { "Default": "Server=XX.XX.XX.XX; Database=TestDB; Trusted_Connection=False;User ID=TestUser;Password=xxxxx;" }, "App": { "ServerRootAddress": "https://localhost:XX", "ClientRootAddress": "https://localhost:XX/", "CorsOrigins": "https://localhost:XX/" } } 6) And below is the snippet of the appappconfig.production.json file
{ "remoteServiceBaseUrl": "https://idmsvnext.infogroup.com:XX", "appBaseUrl": "https://idmsvnext.infogroup.com:XX/", "localeMappings": { "angular": [ { "from": "pt-BR", "to": "pt" }, { "from": "zh-CN", "to": "zh" }, { "from": "he-IL", "to": "he" }, { "from": "es-MX", "to": "es" }, { "from": "vi", "to": "en" } ], "moment": [ { "from": "es-MX", "to": "es" }, { "from": "zh-Hans", "to": "zh-cn" }, { "from": "vi", "to": "en-gb" } ] } }

Hi,
Could you also share your Angular and angular-cli versions ? If they are not on the latest version, could you try to upgrade them ?
There has been many improvements in Angular and angular-cli for decreasing the published bundle sizes.
Thanks,

Hi, I upgraded to the latest version of angular and angular cli(8.3.2), earlier it was 8.0.1 and tried publishing the code again. but there seems to be hardly any change in the file size and so the performance. Below are the print screens
Please suggest.

Thanks for the analysis, we have checked our website and its functioning all normal with slowness in loading the login form. We are not getting any CORS error. Could you please try the secure url i.e.
https://idmsvnext.infogroup.com
We have deployed our website on an on-premise server and it is not hosted in cloud. When deployed in azure cloud, it seems all the bundles are gzipped and cloud itself is taking care of unzipping/caching the bundle files.
We checked the site you have deployed in azure and the bundle size for main.js is 4.5MB but it is cached. In our case the main.js is 4.4MB but evey time we are loading the landing page the file is getting downloaded and hence the slowness.

We were having performance issues and I found this ticket
one of the first comments didnt seem to make sense: "4.4 mb and it is a bit high."
After some investigation I found we were having a compression issue. Our files now range about 1MB down from ~4.5MB
For more info see: https://docs.microsoft.com/en-us/iis/extensions/iis-compression/iis-compression-overview
