Last week, we detect un performance problem during the creation of a Excel document with JCom. The creation is nearly ten times slower than usually, it seems the problem comes from the SpoolSv.exe process executed during the creation. We have never had this problem before. An other information that could be interesting in that we changed our antivirus software a few weeks ago.
Does someone have an idea of what this problem could be ?
We are using JCom for part of our Excel interaction, but for creating and populating worksheets with values, we can use Apache POI - the Java API for Microsoft Documents
