This is not a question but a list of issues.
1. Download is huge (707 MB). Downloading new builds results in downloding redundant copies of IPP, TBB and MKL whose versionsdo not neccessarily change each time with the compiler. Can you spell wasted bandwidth?
2. Folder hierarchy is poorly thought out and it keeps changing -- with every new release I have to edit all include/executable/library paths for both 32-bit and 64-bit versions of all tools (ICC, IPP, MKL, TBB) in Visual Studio. That is reallya major inconvenienceconsidering the fact that the latest compiler builds are unstable and/or produce slower codeso I often have to revert to the previous version.
3. Serious regressions aren't addressed quickly enough (#524001 comes to mind).
4. Important behavior changes aren't properly documented in Release Notes (applies to all compiler releases so far,not just 11.0).
5. Both 10.1 and 11.0 produce a bit slower code than 9.1 at least for me. That isn't exactly progress in my book.
Those are my top five. There is more but I won't bother you any further. Thanks for your attention.
