| Subject: | EPICS 3.15 IOC built much slower than 3.14 |

Dear All, After I upgraded EPICS base from 3.14.12.2 to 3.15.3, my IOC was built much slower than before.
So I did a brief test on Debian Jessie: To build two identical example IOCs with 3.14 and 3.15 respectively, the result is that it takes about only 1 second for 3.14 but 10 seconds for 3.15.
For 3.15 IOC, most of the time is taken by the following two perl-related commands: perl -CSD /usr/lib/epics/bin/linux-x86_64/dbdExpand.pl -I. -I.. -I../O.Common -I../../../dbd -I/usr/lib/epics/dbd -o example.dbd base.dbd xxxSupport.dbd dbSubExample.dbd exampleHello.dbd initTrace.dbd
Whereas for 3.14 IOC, there are two similar commands but are executed fast: perl /home/vagrant/base-3.14.12.2/bin/linux-x86_64/makeIncludeDbd.pl base.dbd xxxSupport.dbd dbSubExample.dbd exampleHello.dbd initTrace.dbd exampleInclude.dbd
perl /home/vagrant/base-3.14.12.2/bin/linux-x86_64/registerRecordDeviceDriver.pl ../O.Common/example.dbd example_registerRecordDeviceDriver /home/vagrant/epicsApp/app314 > example.tmp
Does it also happen on your EPICS 3.15 environment?
Thanks, Lin Wang
