Sure, but we dont maintain nor correct the recommandations found on
various Internet pages ;)

BTW, a google search on "tcp_tw_recycle" gives many results on problems
with this setting, not improvements.

Also, many "recommandations" found on Internet suggest to disable
tcp_timestamps, only because it adds 12 bytes to TCP header.

Apparently you chose to follow the tcp_tw_recycle=1 recommandation, not
the tcp_timestamps=0 one ;)
