WebPagetest 2.10 is now available: https://sites.google.com/a/webpagetest.org/docs/private-instances/releases/webpagetest-2-10
The main highlights are:
- Fixed support for Firefox 18+
- Eliminated a lot of wasted time on the test agents so agent thruput should be increased pretty significantly (10-30%)
- Progress UI is now ajax-based so no more constant refreshing
- Added visibility into IE 10’s OCSP and CRL checks

Packet lost rate (see below). Even if I specify how the plr should be using custom connectivity profile, there is nothing in the output.
