#1 Burning Software

Hey all.

I'm trying to set the cache size at the call to StarBurn_CdvdBurnerGrabber_Create ( p__LONG__CacheSizeInMBs != 0 ).

When retrieving the cache-size afterwards ( StarBurn_CdvdBurnerGrabber_GetDeviceInformation ), it's always the same (default) cache-size...
is this normal behavior???

Thanks

Looks like you've misunderstood the meanings. There are TWO caches. One hardware (built into the drive) and one software (we're using to buffer I/O operations). _GetDeviceInformation(...) returns the size of HARDWARE cache we cannot change by ourself. So it's always constant. And amout of software cache we use cannot be re-read. Assuming you know how much you set and we've allocated all the size successfuly

you're makin' me an expert..

OK, I understand now....Hardware-Cache (located on the drive?!?!?!?) can be raed, but not changed...OK. Software-Cache can be set, but not read? There is really no way to find out, what cache size is used, when set to 0 (default) ?

This it not really nessecary, only need it for UI. Take a look at the (wrong interpreted) dialog:



just want to show enduser, what cache size is used, when selecting 0 (default).

just askin'

Exactly!

When you're creating and CdvdBurnerGrabber object you're passing the number of cache you want it to use. So if you've passed some number and device was created you can assume the passed size to be correct. If 0 would be passed CACHE_SIZE_IN_MBS (64 megabytes) is used. This is what you can show to user...

64 MB is default.

That's what I wanted to hear

Many Thanks

This was mentioned in the headers

Hello Support,

How to provide Cache Size in StarBurnX, while burning image to disc. Is it supported in StarBurnX to provide the cache.

Thank you in advance.

Default 160 MB of cache memory should be OK for most needs

Hello Support,

I didn't get that.
How to use Cache Size in case of burning Data to disc ?

Waiting for reply.

You don't need to "use" it. It's internal buffer used by burning engine.

Hello,

Generally speaking you can specify the size of IO buffer which is used by DataBurner ( and by other Burners). The Drive object has property - CacheSize.
Usually, you DON'T need to change size of this buffer. One case when you may change size of this buffer is - "using" DataBurner on the WEB page. In fact you may reduce size of buffer in order to "save" memory!

Hello,

1) I asked about Cache Size, because as per the concept of Cache, it works like RAM only for Burn Engine. So I thought that if we can increase this cache size then burn process will become fast.
2) So only for this reason, I asked you about this property which there for a drive, But not used by me.
3) How to use that? I want to use that effectively to reduce the time required for burning.


Thank you.

You cannot jump over your head. You cannot increase burning speed.

From Documentation of StarBurnX
Drive.CacheSize -
This property specifies the size of the internal cache (in MB) which is used during the burn operation.

1) Will you please guide me, What value should I assign to this Drive.CacheSize?
2) What is the difference if Suppose
a) I set this value as 64 MB
b) I set this value as 160 MB
if I burning 4 GB data on DVD +RW?

Will you please kindly give me a change-log with new build, whenever it is ready, So that I don't have to test each class for reported problems by me or any user?

Keep it default. Should be OK for 99% of the cases.
