Attacking the same problem from another angle there is<br>
|
||
a "test version" of the Linux sg driver (2.1.35) on<br>
|
||
<a href="http://www.torque.net/sg">http://www.torque.net/sg</a><br>
|
||
<p>
|
||
Francois's tests show that it cures his Snapscan problem.<br>
|
||
I encourage others to try it. It will probably reach the<br>
|
||
production kernel around 2.2.12 .<br>
|
||
<p>
|
||
Abel Deuring <<a href="mailto:a.deuring@satzbau-gmbh.de">a.deuring@satzbau-gmbh.de</a>> is also getting<br>
|
||
some impressive speedups with his SnapScan using larger<br>
|
||
buffers and "pseudo" command queuing.<br>
|
||
<p>
|
||
Also anyone having out of memory problems with Linux when<br>
|
||
using SCSI devices (not just sg) may like to try 2.2.10-ac10<br>
|
||
that has improvements in the page allocation algorithms by<br>
|
||
H. J. Lu. Those changes seem to help a lot and hopefully<br>
|
||
will appear in 2.2.11 .<br>
