I use RECOLL to search out PDF research documents for biological
investigations. Since installing Artful 17.10, the results of a document
search are delayed from appearing on the screen by as much as six
minutes.
I've cleaned all RECOLL files and directories from my machine and
clean-installed version Recoll 1.23.2 + Xapian 1.4.4. I compiled Xapian-Core,
Xapian-Omega, and Xapian-Bindings on 14 September using latest version of gcc,
version 7.
Since I only index biological papers, I restricted TOPDIR to
/home/denny/backup/Reprints. The subdir Reprints holds 26 directories
labeled as A..Z, with the dominant file-type PDF.
In the state of Florida there is a biological reserve named Paynes
Prairie where much of the research at the University of Florida is done.
I used the search pair of Paynes Prairie just as it appears here, and
used "all terms" as search criteria.
In the search, the result count est. was 64, and the count appeared
instantly. Then 4 minutes and 30 seconds elapsed before the first 24
file elements appeared. The second 24, returns 25-48, took 6 minutes and
10 seconds, and the last set, 49-64, took 5 minutes and 30 seconds to
appear on the screen.
In using any term as search criteria, the Results count est. of 943
appears immediately. The sets 1-24 and 25-48 appear on screen nearly
instantly (presumably from the all terms search), but subsequent sets of
the 943 return in a diminishing series, 1:35 then 0:45, 0:20 and by the
300-series of returns the interval is between 0:15 and 0:08 seconds.
I noted that the hard drive access light was on continuously during all
of the search series.
Searches with Query language, all terms and any term each show long
delays in returning results. Only the file name search responds with the
quickness that I remember from an earlier install.
If I make input to RECOLL from a terminal window (I use guake), the
response is so fast that I would call it "instant". All 64 file listings
appeared in a continuous cascade.
