Hi,

Do low hit ratio (less than 70%) for Export/Import buffer causes performance issue?

I didnt get any Note related to this.

Any help will be appreciated.

Thanks,

Saurabh

low hit ratio will cause problem when you have big swap value in same row information.

low hit ratio with very small swap value wont be any problem.

Hi,

as far as I know there is a note recommending a hit ratio of 80% or more for that buffer. Because of the usage of this buffer, no better ratios can be achieved.

Thanks everyone,

Basicaly all the buffers(Program/Nametab/CUA/Screen/Genric Key/Single record) has hit ratio around 99% , but for export/import buffer its 60%. which is indeed less.

This is what i intended to ask, if this low hit ratio for export/import buffer has much impact ?

Any note if anyone remembers?

Thanks,

Where do you face performance problem? Mostly export/import buffer is used by ALV objects and thus if you see a higher amount of swaps in that buffer can impact your ALV reporting performance. As long as you dont see any overflow/swaps in that buffer, that may not cause any performance problem.

No. Hit ratio is not much relevant here.

You may need to look where there are buffer overflows in this buffer.

Dear Saurabh,

Please explain exactly which buffer in which memory are you talking about.
