<PropertyGroup> <ServerGarbageCollection>false</ServerGarbageCollection> </PropertyGroup>

Asyac

1. logger   

remember using async method to write log. Otherwise, your cpu will be high and the service will be slow.

below using nlog as example:

1 2 3 4 5 6

<targets async="true"> <default-wrapper xsi:type="AsyncWrapper"> <wrapper xsi:type="RetryingWrapper"/> </default-wrapper> .......... </targets>

Cache

remember high traffic service must to set cache on Application, Database and Client
if you use cloud platform (AWS, Azure and GCP) , you can use CDN to reduce traffic for service

• Application
• use redis/cache server to cache not Infrequently changing data
• Database
• Client 
• use http cache

Request Timeout

remember high traffic service must to set request timeout on Application and  Database

* AP

* DB
