Description Felix Schulte 2006-02-20 18:44:02 UTC

Perl allows the usage of sfio for I/O operations instead of stdio which usually results in very nice performance boost in I/O-heavy benchmarks (AT&T claims 30% performance improvement in some benchmarks).

sfio is available via libast in the ast-ksh package (/usr/bin/ksh, NOT
pdksh), the Suse source RPM name is ksh-93q-10.src.rpm

Hm, I think I read this before, but I cannot find any existing report. Reassigning.

Comment 2 Michael Schröder 2006-02-21 14:19:39 UTC

Maybe, but: 1) I don't know what this breaks and,
2) it is much too late now to change this. SLES10 is feature frozen.

So maybe we can try this for SL10.2 and get it into SLES11...
No promises, though.

perl has a test suite. And a small announcement to the openSuse community may be helpful that the community checks for regressions, too.

The RFE was for Suse Linux 10.1 but 10.2 is ok, too.

Any news or status update? Any problems found?

Comment 5 Michael Schröder 2006-03-27 16:09:18 UTC

Well, this is a post SLES10/SL10.1 thing, so no, nothing new. We haven't even tried it yet.
