Dear all,
about quite some time ago I made some tests with an earlier version of Aspose.Cells for Java (2.4.2). Our Goal was to modify an existing Excel file and export it to PDF. Although I was quite impressed by functionality, speed and quality of output my company decided to postpone further tests for the time being.
Recently I reactivated my test suite and updated it to the latest Aspose.Cells version 7.7.2.
In Windows quality and speed of PDF export still is impressing, although page layout (mainly page borders) is not exactly what an Excel printout looks like. I suppose that is because of the "Evaluation" message on top of the page and by installing a valid license page layout could be better.
But when running onUnix (I trie out AIX, which would be our destination platform for production environment, as well as Linux) there are two problems:
- Performance
- Export time of a one-pager
- Windows: 3s
- Unix: 6s
- Export time of a 10-pager
- Windows 10s
- Unix: 4m !!
--> Especially on the AIX host CPU power and memory should'nt be a problem.
- Compared to Windows the fonts are smaller and much denser
- German umlaut characters (like äöüß) are printed over by the next standard character.
When using the old Cells version v2.4.3 both performance (only 13s on AIX for 10 pages) and quality are much better compared to v7.7.2, although there is still a difference compared to Windows.
Are there any tweaks to enhance performance and quality with the current Cells version on Unix? Especially an export time of 4 minutes would be an absolutely no-goer for us. The same is true for the umlaut problem.
Many thanks in advance for your assistance.
Best regards,
Benjamin
