Hi Jay,

 

I don’t see this problem.

 

Here is the output from the cygwin shell wrapping the caget inside “date” commands.  13IDC:m2 is a PV on a vxWorks IOC.

 

# date ; /cygdrive/c/epics/base-3.14.11/bin/win32-x86/caget 13IDC:m2 ; date

Wed Feb 16 14:43:42 CST 2011

13IDC:m2                       5000.1

Wed Feb 16 14:43:42 CST 2011

13IDC:m2                       5000.1

Wed Feb 16 14:44:02 CST 2011

 

# date ; /cygdrive/c/Program\ Files/EPICS\ WIN32\ Extensions/caget 13IDC:m2 ; date

Wed Feb 16 14:46:22 CST 2011

13IDC:m2                       5000.1

Wed Feb 16 14:46:22 CST 2011

 

So it is taking less than 1 second to run caget from both the win32-x86 and cygwin-x86 architectures from base-3.14.11, and from the EPICS Win32 Extensions version.

Hi EPICS folks,

      I’m running caget and caput utility functions from cygwin and DOS on a Windows XP system to get and put data to a VxWorks IOC on the same subnet. I would like to know if there is some option to help speed up the execution of these utility functions. For both sets of utility functions, the majority of the execution time (4-5 seconds) seems to be spent running the ca_context_destroy function at the end. I don’t see this delay when running caget and caput functions to get and put data to a Soft IOC running on the same Windows XP computer. I don’t understand why there is such a delay just to clean up at the end.

 

     I’m using epics base v3-14-11 for cygwin and EPICS WIN32 Extensions Version 1.40 (Build 40) for DOS.

 

Thanks,

Jay Steele
