I was hoping to get a group concensus on the use of softupdates.

The FAQ says that "Soft Updates are still in development as a whole" but
  they do sound mighty appealing.

Are softupdates used my many without a great danger relating to the
problems discussed? Can I consider it safe to implement them on
filesystems used heavily with a lot of disk activity to generally speed
the system up?

One area that I wanted to try to improve (without forking out $$$ for
scsi host adaptor and disks) was the performance of the system during
anoncvs updates. My vmstat output looks like this during it:

procs memory page disks faults cpu
  r b w avm fre flt re pi po fr sr wd0 cd0 in sy cs
us sy id
  1 7 0 111908 484404 215 0 0 0 0 0 8 0 243 522 25
  2 1 98
  0 7 0 111912 484400 279 0 0 0 0 0 59 0 296 569 84
  1 1 98
  0 7 0 111912 484400 709 0 0 0 0 0 27 0 261 821 53
  2 2 96

I understand that the 7 in the second column indicates that my disk is
blocking and is the bottleneck. Will softupdates drastically improve
this? (ATA 66 7200 IDE disk.)

TIA for the responses,

DS
