compare your adsm settings against those of TCP/IP...  
     stuff like your tcpwindowsize, floatingwindowsize (what ever it is  
     called) and others... adsm can't use it if the system won't let it go  
     that high!
      
     Most often if you have adsm communication values set higher than they  
     are under TCP/IP you will experience unexplained hangs or abends.
      
     just a thought
     later,  
          Dwight

Hi everybody, I need some help about performance.
      
  My customer is using a 12/24 GB Internal Tape Drive attached to a Netffinity
with OS/2 running on it. We took a backup of about 1.1 GB and the delayed time  
was 1 h and 38 minutes. However, the theorical rate of the device is of 1.1  
MB/sec and 2.2 MB/sec with compression.
      
  We've tried using the tuning parameters listed in the Tuning and Performance
Manual, such as TXNGROUPMAX and TXNBYTELIMIT up to the maximum values, but,  
however, the performance hasn't changed. Has anybody any recommendation?.
      
  Thank you very much.
      
                                                        Mariajo.
