Run/deploy slow under Tomcat8

Aspose.Total Product Family

I am licensed to use Aspose total for JAVA and am currently using Aspose.PDF v23.1 and Aspose.Words v23.1 and Aspose.Html v23.1 running on Tomcat 8.0.14 using JDK 1.8.0_31,below is my Maven dependency:

com.aspose
aspose-html
23.1
jdk1.8


com.aspose
aspose-pdf
23.1


com.aspose
aspose-words
23.1
jdk17

I create a servlet which only contains few code, such as create a new document with pdf,html or word and pack it as a war.

Run it on My develop machine with the following:
OS: Win7 SP1 64bit 202110
Tomcat: v8.0.14
JDK: v1.8.0_31
The issue is It will cost even ten more minutes to complete the code.
I also test the war under Tomcat7 on this machine, it seems no problem, and I also test the code under JDK1.8.0_31 as an application, still no problem.

Attachment is the web applcation source, also attached the response with time I got on my development win7 machine.
src.zip (3.9 KB)

tomcat8 response.zip (544 Bytes)

Then, I run it on server for production env with the following:
OS: Linux 3.10.0-1062.4.3.el7.x86_64
Tomcat: V8.0.53.0
JDK: v1.8.0_71-b15
There is another kinds of issue, Tomcat will start the server with a very very long time(30 more minutes) .

Our production env is Tomcat8, we need ASPOSE work on this env, can you investigate and resolved this? Thanks.

Best Regards

Please note that the performance of the APIs are measured on subsequent runs of the code snippet as on the first run, API loads necessary resources into the memory. Furthermore, have you tried with the latest available versions of the APIs i.e. 23.7? We request you please try using the latest versions of the APIs and let us know in case you still notice performance issues. We will log an investigation ticket and share the ID with you.
