Disk cache question

[Corv]

Latly I have been examining differnet settings and such to get the best perfomance I can. I stumbled acrossed the disk cache/memory thing.

the 1.3d manual indicates to disable disk cache"smartdrive" due to the fact that duke does its own internal cacheing, and smartdrv would get in the way.

then the memory leak was detected by 3drealms

the 1.5 manual indicates to ENABLE cache"smartdrive" if you have more than 8MB an no mention of smartdrv causeing any conflicts.

Now the question is, Does the manual comments(1.5) in this case also pertain to 1.3d aswell(becuase of the memory leak) or was it changes made in 1.5 that allows the use of smartdrv properly to either boost performance or aid in the memory link?

Thanks-Corv

I would use Smartdrv only if running in pure DOS.

ya, thats what I assumed, however the question is still unresolved. I corrected it slightly aswell.

Why noy attempt to measure the performance?

well im trying to findout if changes done in 1.5 allow the use of smartdrv.-- or if its just something they couldn't really fix and said , heck use smartdrv....

thanks cyborg

Smartdrv just caches the file reads in memory. The downside is that it takes up memory.

So, if you don't have much memory (<=8mb), then you're probably better off letting Duke have the memory instead of taking it for storing files...

With a memory leak in 1.3, that would make it even more important to give Duke all the memory it can get http://www.3drealms.com/ubb/images/icons/smile.gif (before it blows up...) http://www.3drealms.com/ubb/images/icons/frown.gif

So, with 1.5 (memory leak fixed) and enough memory (>8MB), there's no reason not to use Smartdrv.

Note that you shouldn't use smartdrv under Windows; just under straight DOS. Windows has its own drive caching built in.
