Hello When tried do convert ppt file (You can find attached the original file, but I had to delete some slides, because accpet only 2Mb attachments), it takes more than 1 minute to convert.

Is possible to improve the performance? I tried to put 6Gb on JVM, but still taking a lot of time to convert

Another problem is that when generating in linux the font is getting bigger than on windows. What is missing? maybe some fonts? youcan find a screen shot attached

can you help ?

Hello,

Thank you for your inquiry.
I tested the Powerpoint file you provided and found that the program running time was indeed about a minute. I have logged the issue into our bug tracking system with the ticket number SPIREPPT-1888. Our development team will investigate whether it can be optimized. Once there is any update, I will inform you in time. Sorry for the inconvenience caused.
In addition, you mentioned that the font size of the result file on the Linux system is larger, which is caused by the "Calibri" font not installed on your Linux system. Please install the "Calibri" font to the Linux system before testing.

Sincerely,
Annika

Sorry for a Late reply

today I tested just replacing the new jar version and I got the same results

It Takes about a minute to convert

DO i need to do change something on my code to have a faster conversion?

Can you send me how long it takes for you to convert and the code used?

Hello,

Thanks for your feedback.
I tested your PowerPoint file with the new version and the program took around 34 seconds. The test time of the previous version was about 64 seconds. My test environment is Windows10, 8G. I have attached my test project (JDK1.8 ), please download and test it on your side. In addition, please test on multiple computers to confirm whether the program still needs to be optimized.

Sincerely,
Annika

Hello,

Thanks for your feedback.
The running time of the program is related to the memory size of the system. I tested it on the 10G centOS 7, the program time was 29 seconds, and the program time on the 6G centOS 7 was 47 seconds. Our developer feedback can only optimize so far. Therefore, we recommend that you increase the system memory to increase the speed of the program.
Thanks for your understanding.

Sincerely,
Annika
