  TCP/IP FTP performance? 
 The Question is:
 
We have notice that a FTP transfer of a 16Mbyte
file between our Alpha 2100 and a Sun system
takes about 2.5 minutes across a 100Mbit ethernet
interface. If transfer is the same file from the
SUN to a PC running NT 4.0 the transfer takes
about 2 seconds.
 
Why does the Alpha take so much longer to transfer
the file?
 
As a test I connect a NFS device from the ALpha
to the PC, using Reflection Xsuite the PC and
UCX Version V.2 on the Alpha. Then using FTP on
the PC I transfered the same file from the SUN
to NFS device on the PC, again the transfer
took about 3 seconds.
 
Were do I start looking for performace problems?
 
 
 
 
 
 The Answer is:
 
  Please first determine what version and TCP/IP package is installed
  on OpenVMS, and check for any available ECO kit for the version.
 
  The most recent version of TCP/IP Services for OpenVMS (formerly UCX)
  is V5.0 (as of 7-Jun-19998), and V5.0 can be installed on OpenVMS V7.1
  and later.  (Your reference to "UCX V.2" would imply TCP/IP Services
  V4.2, and an ECO kit is available for this release.)
 
  Then check for the appropriate process quotas, particularly if you are
  "pushing" the file from OpenVMS to the remote system.
 
  Here is an example set of process quotas:
    Maxjobs:         0  Fillm:       300  Bytlm:       204800
    Maxacctjobs:     0  Shrfillm:      0  Pbytlm:           0
    Maxdetach:       0  BIOlm:      1024  JTquota:      16384
    Prclm:           0  DIOlm:      1024  WSdef:         2048
    Prio:            4  ASTlm:      1000  WSquo:         8192
    Queprio:         0  TQElm:      1000  WSextent:     16384
    CPU:        (none)  Enqlm:      2048  Pgflquo:     102400
 
  Then ensure the appropriate paged and non-paged pool, using AUTOGEN
  with FEEDBACK, and then reboot.  Make sure you have cleaned any
  "cruft" out of SYS$SYSTEM:MODPARAMS.DAT, to avoid any restrictions
  on the parameter settings generated by AUTOGEN.
 
  If the ECO kit is applied and the process and system quotas are adequate
  and the performance issues are not resolved, please contact the Compaq
  Customer Support Center for further assistance.
