I've been using the Simple Channel Access libraries under NT, and have
noticed that the time to make an initial connection is quite long. For
example, using the routine cache_getbyname, it takes about 45sec to get 140
values initially (~0.33sec/value). I've also tried the batch routines
que_get and do_get, with a marginal improvement (to ~0.25sec/value), which
is still pretty difficult to live with. Can anyone tell me if they have a
similar experience? Is this an inherent limitation of these
functions/library, or is it possible to improve the performance? My ioc
uses epics 3.13beta11 and my client (based on LabVIEW) has used sca3.dll
and ca.dll for 3.13.0 and previous versions.
Thanks
