Problems with Samba and OS/2

I've got a couple problems with Samba<-->OS/2 communications.  First, 
though, here's my environment: 

Samba machine:
  Celeron/400 /w 256MB of RAM
  IDE hard disks
  100Mbps 3Com NIC
  RedHat Linux v6.0 + all RH-released updates + kernel v2.2.13
  Samba v2.0.6
  filesystem: ext2, cache size: dynamic
OS/2 machine:
  Pentium 3/550 /w 256MB of RAM
  SCSI hard disks
  100Mbps 3Com NIC
  OS/2 Warp /w latest FixPack applied
  TCP/IP stack v4.0 /w updates applied
  filesystem: HPFS386, cache size: 16MB
And here are the global parameters from smb.conf:

   interfaces = lo eth0
   bind interfaces only = True
   hosts allow = 127. 192.168.0.

   netbios name = corona
   name resolve order = hosts bcast
   dns proxy = no

   printcap name = /etc/printcap
   load printers = yes
   printing = lprng

   max log size = 50
   log file = /var/log/samba/log.%m

   security = user
   encrypt passwords = yes
   smb passwd file = /etc/smbpasswd
   null passwords = yes

   domain logons = yes
   logon script = netlogon
   logon path = /home/samba/netlogon

   local master = yes
   domain master = yes
   os level = 33
   preferred master = yes

   client code page = 437
   lock directory = /var/lock/samba

   time server = yes
   shared mem size = 524288
   socket options = IPTOS_LOWDELAY TCP_NODELAY

1.My first problem: write performance.  Here's some statistics in 
transferring a 10MB file between machines.  Note the disparity in 
writing a file to the Linux box from the OS/2 machine via Samba.  (I 
transferred the file several files, to load the disk caches, before 
getting these stats.) Alas, these values are all too consistent.  

Samba --> OS/2
  ftp = 1.1 seconds
  smb = 1.5 seconds

OS/2 --> Samba
  ftp = 1.2 seconds
  smb = 6.0 seconds

Any one have a clue why writing to a Samba share from OS/s takes 5 times 
as long as a ftp transfer to the same subdirectory on the Linux box??  

2.  Why are there still extended attribute (EA) problem on Samba 
shares?  Here's a test: Open the OS/2 system editor (e.exe), write 
some text, and save the file as n:\testme.txt.  The attempt to save 
the file causes an error that the file cannot be written.  In fact the 
file *has* been written.  It is the writing of the EA for that file 
that causes the editor to choke.  If you Cancel that "Save As" 
operation you will see that the newly created text file is indeed on 
the specified Samba share.  What can I do to fix this EA problem?
