O.K, I did some more testing using a stop watch to verify the speeds that NetPerSec was reporting. NetPerSec IS reporting the correct speeds - transmitted file size was about 2.2 MB.
Based on input from this thread, I have compared 3 scenarios (all standard ports are enabled):
1. Avast uninstalled - I pretty much get my full upload speeds (90-92KBS), 24 seconds
2. Avast installed, outbound scanning on - about 40KBS, 59 seconds
3. Avast installed, outbound scanning off - about 81-83KBS, 27 seconds
FWIW, NAV always gave me the 90-92KBS speeds after it scanned any attached files.
So again, as indicated in this thread, is this a significant performance problem and if so, how long does it typically take to get something like this fixed?
Thanks,
Harvey
