1KB SMB packet size killing throughput (XP to Ubuntu)_

I am investing (and looking for help for) very low transfer rate from XP
client to Ubuntu samba server.
More details are at
gist : write is getting only 1-1.5MB/s over ethernet.
The main culprit seems to be 1KB SMB packet. tcpdump and strace show XP
sends only 1KB each time. I don't have enough knowledge to know whether
this is a symptom, cause, or a side effect of the real problem.
There are couple of other strange issues on actual data consumption by smbd
XP client : netstat on server shows "1092" bytes many times in receive
buffers, indicating server is not consuming the data fast enough.
Ubuntu client : Though the transfer is twice as fast, I almost never notice
data on receive buffer. indicating smbd is consuming data faster than sent
Is XP client making smbd work more?
