This script checks amount of bytes sent for different pages and different sc-status.
EXTRACT_EXTENSION(cs-uri-stem) AS PageType,
SUM(sc-bytes) as TotalBytesSent,
TO_INT(MUL(PROPSUM(sc-bytes), 100.0)) AS PercentBytes
Looking at the list below a couple of things are interesting.
- You have 2,2 Gb of .GIF-data sent by the server with sc-status 401. In one of my other post i discussed setting picture folder to anonymous access if your domain uses NTLM instead of Kerberos. These 2,2 Gb could probably be removed/reduced in that case.
- Same for the ICO files if you have them in a separate folder
- You also have 650 Mb of data that is .GIF’s with 404. 404 means file not found. Go fix!
