With Clearcase I have
not seen many issues using TAS or Samba. I have seen many issues with AIX
and with Clearcase Web.
With a dynamic view in
Clearcase you just build, no need to sync. With Perforce you have to sync
to none, then sync again to download the files.

I
disagree with the fact that sync is a bottleneck with perforce builds compared
to ClearCase. For clearcase TAS is a very big bottleneck. The build times
increased 5 fold especially with the cobination below. There are several
whitepapers discussing this and numerous RFE's submitted to Rational.
-Dynamic
Views, TAS, Ant/Java build environment on a Windows box.
One of
the problems identified is over-the-wire CIFS/SMB calls of
type QUERY_FILE_INFORMATION.(220,000 calls observed in the build
environment which was reviewed in tandom with
rational)
To
overcome these issues many companies had to go the NFS route and the build times
dropped significantly, but which inturn has its own security problems combined
with Windows.

With
Clearcase there is no user admin. I agree that the developers complain
less. The release engineers complain more because Perforce adds to the
build times because of the sync.

I'm not
sure that I agree - I support around 50 users and after the initial load of
the code from the previous system and preparing the users I have spent hardly
any time on support for Perforce (probably a less than 5% of my
time).
User
admin is a trivial problem (here at least).
Most
importantly the developers like it so they don't try to work against it or
around it or moan about it.

We are looking to move to Perforce from
Clearcase.
Replying to what you said
:
" ClearCase's
learning curve isn't so much "long" as it
is "steep". You will
definitely need a dedicated
ClearCase
"Administrator" (i.e. to make sure the
various services are
up, make sure hardware is
optimised,
etc...)"
I find the same with Perforce.
You need to administrate users which you don’t have to do with
Clearcase. You also need to handle setting up branches in Perforce and
help developers. And I find it a pain dealing with optimizing the
Linux OS. I also found when I first started with Perforce that the doc
didn’t have many examples.
