Size difference

[adragan]

Did anyone notice the size difference between Delphi versions ?

 

Same project, same UniGui version, same compiler options ( with debug ), 32bit  :

 

Delphi 2006 ->    6.5 MB ISAPI DLL

Delphi XE7   -> 32.5 MB ISAP DLL  !!!!!!

 

It drastically limits the max no of users on a 32 bit server !

Is it worth upgrading ????

Yes, it is a know issue and debated among Delphi developers for a long time.

Actually you must look at "Release" code without  debug info for a better comparison.

 

It drastically limits the max no of users on a 32 bit server !

 

 

No, why?

 

 Is it worth upgrading ????

 

 

Yes, but it depends on your project. If you need 64-bit support you must upgrade.

Maybe I don't understand how it works , but don't you make a separate thread of execution for each user , that is a new "copy" of the isapi.dll in memory ?

If we consider that there is no DB server and that the operating system takes only 500 Mb (??).

 

Then 3500 Mb of RAM/ 6.5 Mb = 538 (aprox ) max theoretical users / server.

On XE7  3500 / 32 = 109 max uses / server.

 

That is 5 times less users.

No, server DLL is loaded only once and for each user a new session is created which only occupies the amount of memory needed to create instances of MainForm, MainModule and etc.
