We've just published newest revision of Yandex' em driver at 
http://people.yandex-team.ru/~wawa/em-6.2.9-yandex-1.15.tar.gz.

Main improvement of this version: driver does not use TX interrupts at 
all.  So, interrupt rate reduced significantly.

There are also several small bug fixes and tiny patch set explanation in 
the file README.Yandex.

WBR,
