TppArchiveDevice very slow


we are having a problem where creating an archive with TppArchiveDevice is very slow.

I've created a test application which creates a report with 2500 records, resulting in a report with 278 pages.
When the application is build with Delphi XE and RB 18.3 it takes 742 ms to generate the archive. When it's build with Delphi Rio and RB 20.0 it takes 1.809 seconds.

Currently I'm at a loss why this is the case, any help would be appreciated.

Thanks in advance.



  • Hi Rene,

    Does your archive contain transparent images? If possible, please send us a copy of the affected archive file and we will run it with both versions and track down the problem. Send files to in .zip format.

  • Nico,

    The report in the test application does not contain transparent images, only numbers.
    I will send you both generated archive files.
