Re: HELP!... What processes can/can't run simultaneously and what throttles throughput on backup sessions ?

Shortly speaking - try to disable compression and things can speed up
dramatically. The reason:
You have to take in the consideration that client-side TSM compression is
single-threaded and thus is limited by the (single) processor power. And
your Domino server might be busy enough. 566kB/s compressed data rate on
low-freq Pentium II/III (even on 4-way server) might be the best you can
squeeze from the processor. The best compression rate I've ever seen was
about 3 MB/s compressed per processor on 750 MHz RS64-IV (RS/6000 M80).
SMP can be utilized only if you increase resource utilization in dsm.opt

5) I have very little knowledge of networking. Could someone comment on
the throughput values we are seeing? Our max of 566 Kb/sec is no where
near the 100 Mb/sec I have been told our ethernet connection is.
