We have recently upgraded to 11.6.1.0 and we have found it much, much, much slower than the version we previously had which is 4.4.2.0.
I have also ran into a lot of Object reference not set to an instance of an object errors with the stack trace being somewhere deep inside ASPOSE. I have no problem with the errors but I would rather have some better explanation of what is going on.
Here is an example of one such stacktrace that I am currently looking at:
