LargeSystemCache question

I currently have the large system cache set 1 when the default is zero and i am loving the way my pc seems to be perfoming but i was wondering about the pros and cons of largesystem cache and if there are any other things i should know about enabling this setting

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control \Session Manager\Memory Management subkey:

This setting was often recommended on "tweaking" sites in the XP era. The knowledge level displayed on these sites was usually very low. In many cases the information was simply copied (copy and paste) from other sites. Most individuals presenting this information knew nothing of what real testing even meant, let alone how to do it, let alone actually did it. Testing was usually nothing more than "it feels faster" which is highly subjective and subject to the placebo effect.

Microsoft documented the setting was for computers used primarily as file servers. What it did was make more memory available for file caching, even to the point where applications ran short. In a file server this makes sense. The purpose of a file server is to share files over a network and for that purpose a large cache is essential and indeed often consumed most of system memory. But nobody cares much about how well applications ran because that is not what the computer was for. In a server OS the default setting for LargeSystemCache is 1.

But most people don't use their computers as file servers but to run applications. A large file cache is a good thing but only if it serves the needs of applications. To support this the default setting of LargeSystemCache in a client OS is 0.

The setting may be useful under some unusual situations but generally not. It depends on how the computer is used.

But all that assumes that the setting actually works on a client OS and of that I am not convinced.

Is there settings in windows that does a long the lines of largesystemcache does but evens out both files and apps? Because i noticed with large system cache set to 0 the app response time is?

Basically i want to be able to do what ramdrive does when you set an app to the ram drive location but without having to install software or upgrade my system

With LargeSystemCache set to 0 the memory manager will dynamically balance the memory assigned to the file cache and applications with the goal of maximizing application performance. Set it to 1 and you tell the memory manager that file caching is more important than application performance. I am not aware of any other setting and doubt such exists. What would it do?

The system file cache provides most of the advantages of a RAMDisk with fewer problems. A RAMDisk is usually not a good use for memory. There are of course exceptions. The trick is recognizing them and that is not easy.

Oh ok, so thats why everyone with pc knowledge say the best way to get performance is upgrade the hardware and leave the rest to windows/os to do the rest then. Alright thank you for all your help
