network extremely slow
...a
I run a samba-server with 15nt-clients on a 100MBit-Switch. Now I
faced extremely poor performance and really have no idea why. I even
dont know if it can be a samba-problem.
When copying myriads of small file from a client to the server or vice
versa I get bad performance:
1000 files a 16kb: ~80seconds = 200kb/second
But this is highspeed compared to copying from nt to nt:
1000 files a 16kb: ~18 minutes (sic!!) = 14kb/second !!
When copying big files (132MB) I get better performance (~3MB/sec,
which still could be much better).
I know this is some kind of question: 'my car dont work. why ?...

Weak CheckSum Question
...ng the rolling checksums on the RedHat 7.2 ISO (against the
checksums in the hash_map) I am getting almost 95% false hits. (ie the
weak-checksums match, but when comparing the offsets the comparison fails).
Is this expected? Is there a stronger rolling checksum I could implement? It
takes about 80seconds to generate all the checksums on a 650MB file, thus I
could certainly use a stronger algorithm which cause less false hits.
Any ideas would be greatly appreciated.
