No one doubts that LR is slow, but I think some of the RAW conversion are simply superior to ANY other contenders offered to date. That fact alone qualifies LR as now.
Instead of of us all lamenting about the speed, how well are your images being interpreted. LR has certainly, IMO, minimized additional time in PhotoShop. That says alot, even in LR's current state..
I just really think too many have focused on the one issue, which is a non-issue, because LR is doing what it is supposed to do - and it does lack a few things yet.... but I do not want this program to be another PhotoShop.
You have a valid point about the converter (it is good and I think will get better). The speed issue is central to the beta testing experience and is definitly not a "non-issue". A program that is unusable because of unacceptable response times (as preceived by some users) is a program that will not be tested by some people and that is a loss for the Beta Program.
I think there are actually 2 "speed issues": one for MACs and another for PCs. I have no experience with the MAC beta but I have been led to believe in the Adobe forums the PC version is slower and therefore less usable than the MAC version which has been in development longer and may have received some speed "tweeks" during the 3 beta releases. The PC version is much more of a "catch-up" release and really runs like a dog at the moment and is way to slow even on a good PC. I use a new Dell 9400 Dual Core 2.16GHz (2Gb RAM) and I could never consider using LR at the moment for serious work, simply because the program response is too slow. The issue for MAC users is (maybe, and this is just my opinion) more of a normal: "it's a beta what do you expect" issue and as has been hinted at will get the real optimization just prior to v1.0.
I have seen hints on the forums that Adobe are working on the issue for PC (and MAC) and because of that I would not be surprised if we saw some sort of improvement with the next beta release.
Is there anyone here who has used both the PC and MAC versions and able to compare on the relative speed of each with similar equipment? Or, is there a member of the Adobe LR team reading these posts that could comment on the speed difference (if there is indeed one and it is not just a myth) between MAC and PC? Is the PC version noticably slower than the MAC?
At the moment I will stick with ACR for working on images and I fiddle around with LR for testing.
I have every confidence that Adobe will get this issue ironed-out for v1.0 and then I can use it properly :-)
