Martin,
IBM says that 1,5 times the CPU and memory is required to run RFS without
noticing less performance but they also say that it varies a lot between
different applications and if you use RFS on all your files or not. IBM
recommends installaing RFS when you do a hardware upgrade.

Dmne: [U2] [Udt] RFS and NFA performance


I am looking for some information about the performance impact of using the
RFS and NFA components of Unidata......

1. Does anyone have experience of just how much use of RFS degrades
performance?  The application concerned does not currently use transactions
though this would be beneficial if the RFS mechanism is to give business
level data integrity.

2. The same client is looking to use NFA to access files on other systems in
a wide area network. Any information about experiences of its performance
would be much appreciated.

Thanks.
