It's a business call rather than file size (as long as you have a 64-bit
file system of course ;-)

64 bit files have a larger internal addressing structure so are
theoretically marginally slower than equivalent 32-bit files and on a
like-for-like basis they are larger for the same data volume held. I have
never taken the time to measure the difference though (feel free to provide
metrics anyone).

It's also worth noting that the 64BIT flag in uvconfig does not enable or
disable 64 bit files - it changes the default to 64 bit. I have seen this
cause some confusion and (sometimes) large numbers of files on a system have
been 64 bit as a result when file sizes don't warrant it.

Distributed files allow you to sub-divide your data into separate
compartments, and different groups of functional users may only be able to
access specific distributed file elements, while others can access
more....... Same program etc. Everyone accesses SALES but NORTH gets
partfile 1, SOUTH gets partfile 2, THEBOSS sees all partfiles.

They can also be used as a neat way of archiving data in bulk if the file
keys and hashing algorithm are based on a relevant key (e.g. include Month
and Year). That way you can offload specific files over (say) 1 year old and
change the algorithm to "default" for partfiles of that number,

Hope it helps..

Subject: [U2] Distributed files poll

How many sites use distributed files?  Any issues you have with them?
Do they impact system performance?



Which would you prefer, a distributed file or a 64-Bit file to get
around the 2 gig limit.
