i remember our irc talk:
08/26/07 14:46:20 <vl> hi kukks
08/26/07 14:46:58 <vl> kukks: With all the changes I've done to InBuffer/OutBuffer in Samba 3.2, I would be grateful if you could give it a test run with OS/2.
08/26/07 14:49:52 <kukks> vl: Hi Volker. Well, I'll test that during the next days. Will give you feedback about the results.
08/26/07 14:50:49 <vl> great!
08/26/07 14:58:47 <kukks> vl: btw - have you removed 'read bmpx'? The last time i tested that (about a year ago), it gave a speed improvement of about 10%. Checked that when copying a large directory tree.
08/26/07 14:59:44 <vl> kukks: Yes, removed it.
08/26/07 14:59:59 <vl> If you can get me a good trace of it, I might re-add it again.
08/26/07 15:00:27 <vl> We don't have a test suite for it and I can't run OS/2, so I did not have anything I could test this quite tricky code against.
08/26/07 15:01:35 <kukks> vl: I'll have a look at that ...
08/26/07 15:02:07 <vl> I know this might hurt OS/2, but 10% speed penalty while it still works correctly, I'd be willing to pay that.
08/26/07 15:04:20 <kukks> vl: yep, it's no pity, if it's not implemented. :-)
08/26/07 15:05:57 <kukks> bbl
My seen 10% speed up with enabled read bmpx was done on a 10MBit network.
I always used "read bmpx" that days...
