This method has major performance issues
.
I really liked not having it mess with my install but if the penalty is too great it is not worth it.
I'm of 2 minds about this issue.
I think it depends on the type of work being done.
If it works to your satisfaction , and is economical you could take the attitude 'that half of something is better than all of nothing'
The performance hit may be no more than the time it takes for some people to find a key on a keyboard (to put it into perspective)
... and providing the result is what you want, I'm sure it would be faster than working manually, yes ?
