When use WinDbg to trace memory usage issue, I found there are million strings which occupy 100+MBs totally. Our application is a financial type APP, so there are ten thousands accounts and each account has many string type properties.
My question is: is there any good articles/resource about tuning memory issue, especial for the string type? Thanks in advance.
You probably need to look at your design.Having Millions of strings is probably not a good idea/design.
Although not sure what exactly your design is,you can tune your strings using
With a normal string object ,every modification on the string creates a new string object and this can bring unnecessary memory pressure.You can alleviate this problem using the stringbuilder class.The StringBuilder object maintains a internal character array and any modifications doesnt create a new string object,rather the internal character array is modified.The string is obtained by calling the ToString() on the StringBuilder object.

String interning is a process where you place unique strings on a common pool and is shared across applications.This reduces the need to create a string if it is already created and interned in the pool.

StringBuilder might be the way to go. You need to split the string. You need large memory and StringBuilder You have to do this directly I think.
