Performance of multiple bar charts per report (RS2000)

I have a 'questionnaire analysis' report. The report consists of approx
25-30 questions and each question has a bar chart attached to it to
show the average score out of five for each multiple choice answer
within a question.
The report ends up containing 25-30 bar graphs all contained within a
List control. The report performance is acceptable using URL access but
is exceptionally slow (over 1 minute) when using SOAP access.
The performance bottle-neck seems to be the multiple calls to
RenderStream to render all of the images that get generated when the
report executes (one for each chart.)
I was wondering if there was any way, still using SOAP, of avoiding
using RenderStream or of speeding up performance. Report caching is not
really an option in my scenario nor is splitting into multiple pages
(user wants everything on screen at once.).
JonYou could make the calls asynchronous (I'm assuming all calls are
synchronous).
