Solaris slow import

 Hi!

We have SUN SPARC Server SunFire v890. A few days ago I've upgraded OS to Solaris 10 10/09 and applied latest recommended patch cluster. After upgrading I have very slow import. I use 9.2.0.7, 10.2.0.4 and 10.2.0.5, different storage system, I've tried to use both ufs and zfs. The results are similar. On IBM AIX it take 2 hours, on SUN - day with identical storage and database parameters. When I use _disable_logging=FALSE, the most popular wait event - log sync, when _disable_logging=TRUE - SQL*Net message from client. iostsat doesn't show disk activity. VDBENCH IO testing gives me good results,

Howdy, Stranger!
