[zfs-discuss] 6604198 - single thread for compression

2007-12-12 Thread Robert Milkowski
Hello zfs-discuss,

  http://sunsolve.sun.com/search/document.do?assetkey=1-1-6604198-1


  Is there a patch for S10? I thought it's been fixed.

It was fixed via 6460622 zio_nowait() doesn't live up to its name  
and that is in s10u4.

Then 6437054 vdev_cache wises up: increase DB performance by 16%  
accidentally re-introduced it.  That was putback in snv_70.  As  
you've noted, 6604198 zfs only using single cpu for compression  
(part II) fixed it again.  And that's available in snv_79.

Neither 6437054 nor 6604198 has been backported to a s10 update yet.

apologies for that,
eric
