Hi Zyx Here’s a final patch for this release – it swaps the order of two data members in PdfReference which causes PdfObject to shrink from 64 bytes to 56 bytes on 64-bit platforms (no size change on 32-bit platforms)
On some PDFs this saves 12.8% allocated memory, and on one particular document
it reduces memory requirements from 3317 MB to 2898 MB (saving 419 MB) on
64-bit platforms. This is in addition to memory saved by previous patches.
BTW There’s still a lot of wasted space inside PdfObject - about 28% of the
space allocated for PdfObject is alignment padding on 32-bit platforms.
Eliminating this will reduce memory requirements by 28%, but requires bigger
changes than just re-ordering members. I’ll look at that for next release.
Cheers
Mark

Hi,
both patches look fine from my point of view, thus I committed them as
revision 1809 and revision 1810:

Thanks and bye,
