Bug ID: 16168
Summary: Eliminate unneeded C4::Context->dbh calls in
C4/Biblio.pm
Change sponsored?: ---
Product: Koha
Version: master
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P5 - low
Component: Architecture, internals, and plumbing

Right now, ->dbh calls are actually quite expensive (they involve DB connection
health checks, each and every time). Some speed-sensitive subroutines inside
C4/Biblio.pm (GetMarcStructure, GetAuthorisedValueDesc) have this statement
my $dbh = C4::Context->dbh;
on top of the code, but they don't always/don't usually need DB handle - not at
that stage at least. This trivial patch eliminates unneeded ->dbh calls in
those subroutines. With it, average GetMarcStructure() running time goes down
from 14 miliseconds to 9 miliseconds (on top of Bug 16166), it also makes
catalogue search profiling a bit easier.
