Completely unrelated to ZFS, but wasn't there some issue with lighttpd
and sendfile() relatively recently (sendfile is the default)? Have you
tried server.network-backend = "writev" ?
I know about the problem with sendfile as I was hit by it on the main
server with Lighttpd + UFS. It has different behavior and it was fixed
in the latest version of Lighttpd from ports. Both servers (main with
UFS and second with ZFS + Jail) are running this fixed version.
I will test it with "writev", thanks for suggestion.
With lower load, Lighttpd is shown in `top` with state 'kqread', but
with higher load in the case of slowdown, the state is 'zfs->io'.
