Document.save performance issue based off image sizes

I have a docx which has about 950KB image. Document.save takes lot of time to process this docx. If I have a docx which has about 10 KB or so, it takes very less time to process. On an average difference between these two processes would be 600 to 800 ms (difference itself). Can you provide a workaround for faster processing of docx s which has huge image sizes?


I see the thread in blocked state. This is very consistent. Regardless of thread in blocked state during save process, time taken is huge based off image sizes on a docx.
