Sorry, it seems it works between two FreeBSD machines.

I tried to say that it had no effect between FreeBSD4.3 and Solaris, on my 
problem. That's what I did previously.

I found discussion on "delayed ack problem"(January 24 and 25) in this 
mailing list.  Though still do not understand why delayed_ack=0 does not 
work for FreeBSD and Solaris.

Anyway I appreciate your helping me.
Thank you,
Yoshi
