[linux-team] Mindcraft manque de serieux



Voici la reponse de novell concernant mindcraft (NT ' vs Netware 4) :

Un texte du leader du groupe Samba : 
   It's not really suprising. They did *no* tuning on the
     Linux server at all. I can well imagine these results being
     accurate without modifying the bdflush and file system
     cache parameters on a Linux 2.2.x kernel. You get a
     factor of 2 performance improvement with Linux and
     Samba when you set these correctly.

     The server itself was a Dell PowerEdge with 4Gb of
     Ram, but in the Linux section of their report it states :

     "The Linux kernel limited itself to use only 960 MB of
     RAM"

     This in itself will kill the Linux performance compared to
     the NT performance. When I did the PC Week
     benchmark using the VA Research box Linux was using
     the full amount of server RAM.

     Note as well that they did the benchmark with RAID
     *Zero* on the box. The PC Week/VA Research
     benchmark was done with RAID 5. This makes a *big*
     difference :-).

     There are other tricks that they used (as I've been
     benchmarking with NT and Samba/Linux for a while I
     know quite a few of 'em). One is to test with Windows
     95/98 clients. To be completely honest Samba/Linux
     doesn't serve Windows 95/98 clients as well as NT does.
     However, Windows NT is *terrible* when serving NT
     clients.

     Note they don't mention the client OS type anywhere in
     the document :-). There are a few other tricks that can
     skew performance also (the Samba "read raw/write
     raw" prameters make a difference when used against
     Win9x clients for example).

     At least this shows that we're starting to seriously annoy
     them :-) :-). I'm quite flattered really.
