Hi,

can Perl profiling be of any help here?

install NYTProf Perl package, then build your IOC with:

$ export NYTPROF=addpid=1
$ PERL5OPT=-d:NYTProf make

Locate the correct nytprof.out.<pid> and open it with

$ nytprofhtml -f nytprof.out.<pid> --open

Hope it helps,

Luca

Hi,

Under 3.15.4 perl script execution takes a lot of time on Linux Mint, while it executes in a jiffy on CentOS.
I added a time in front of the perl call in RULES.db:


time perl -CSD /devel/root/R3.15.4/base/bin/linux-x86_64/registerRecordDeviceDriver.pl   -I. -I.. -I../O.Common -I../../../dbd -I/devel/root/R3.15.4/modules/adcore-master/dbd -I/devel/root/R3.15.4/modules/adsimdetector-master/dbd -I/devel/root/R3.15.4/modules/asyn-master/dbd -I/devel/root/R3.15.4/modules/autosave-master/dbd -I/devel/root/R3.15.4/modules/busy-master/dbd -I/devel/root/R3.15.4/modules/calc-master/dbd -I/devel/root/R3.15.4/modules/sscan-master/dbd -I/devel/root/R3.15.4/base/dbd    -o simDetectorApp_registerRecordDeviceDriver.cpp ../O.Common/simDetectorApp.dbd simDetectorApp_registerRecordDeviceDriver /devel/stage/R3.15.4/iocs/simdetectorioc-master

I think other calls to perl are awfully slow, too..
Any idea why it might be so slow?

Thanks,
Hinko
