Subject: TPAC: Instrument the search results page
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=e342e730fee42afc89bb61fd85280817648cd8cd;p=evergreen%2Ftadl.git

TPAC: Instrument the search results page

Because we want to know why search results can be slowish, add timelog()
entries to pertinent locations in Search.pm.

Quick results on my laptop with the concerto set:
  * 10 results = 1.1 seconds for get_records_and_facets()
  * 50 results = 4.2 seconds for get_records_and_facets()
