[Samba] samba slow at overwriting of files

[don.guido at gmx.net]

dear samba list members,

I recently installed RedHat 8.0 with samba 2.2.7 (already updated, was 2.2.5
before I think, but with the same problem). now I have the problem, that
overwriting of files on shares of that samba machine sometimes is extremely
slow. writing new files is fast as ever. but what seems interesting to me is,
that it depends on how I'm overwriting files.
for example I'm working with homesite 5, which needs up to 15sec to
overwrite a simple html file. ultraedit(a text editor) on the other hand has no
problems with overwriting. 

an other example: copying files with windows commander (now: total
commander) is extremely slow too if I'm copying files that already exist on the target
network drive. on the other hand, if I copy a file in windows commander with
ctrl-C and then paste it on the samba share with ctrl-V, it's fast, no
problem!

has anyone already experienced (and solved) this problem?

any help is very much appreciated!

oliver

ps: my smb.conf settings are below.
