Hi List ,
I posted this on friday but didn't see it on the list so I am posting this again . I am redesigning a major system and particular attension is being given to filesystem configuration and IO . I got this from one supposedly top notch Unix performance tuning expert . I would like to know if anybody implemeted this and what are the impacts .

"The options you want are mount options available only
with Online JFS (not a free product, unfortunately.) The options you want are:
RBS & TEMP files : mincache=dsync, convosync=dsync DATAFILES & REDO files : mincache=direct, convosync=direct
"

TIA
regards,
RS
