There is zero I/O during the run (the DB files are already cached in RAM), which is is one of the main reasons I prefer this benchmark to rebuild library / scan for files. The I/O of reading the files introduces a lot of overhead unrelated to the DB performance, and increases variability (e.g. due to file system caching).

Running this kind of stuff in a loop would likely only hit SQLite's buffer - which is not representative either. Not sure about that.

Not sure about that. If I were to speculate: SQLite doesn't seem to do
any real query caching, and the buffer seems very limited, leading to a
weird spiking performance profile:

I've added some trackstat:
Code:
BCMDS='{"id":1,"method":"slim.request","params":["-", ["playlists", 0, 999]]}
{"id":1,"method":"slim.request","params":["-", ["titles", 0,
99,"tags:acCdefgGiJklnpPDqrROstTuwy"]]}
{"id":1,"method":"slim.request","params":["-", ["albums", 0,

{"id":1,"method":"slim.request","params":["aa:bb:cc:dd:ee:ff",

{"id":1,"method":"slim.request","params":["aa:bb:cc:dd:ee:ff",

{"id":1,"method":"slim.request","params":["aa:bb:cc:dd:ee:ff",
["trackstat", "statisticsjive", "statistics:mostplayednotrecent",

{"id":1,"method":"slim.request","params":["-", ["playlists", "tracks",
0, 999,"playlist_id:475485", "tags:acCdefgGiJklnpPDqrROstTuwy"]]}'
Results are compareable (one benchmark run takes 42s/26s) , only the
spike occurs every third run.
Increasing Database Memory Config to max shaves off ~1sec, but doesn't
do anything else (there is no significant increase of memory
consumption, either)
I'll repeat these with a newly-built library.db and with the the old
SQLite version.

Re: [slim] Why is LMS using such an old SQLite version?
I've just updated my LMS to use the latest DBD::sqlite (1.58) and could run some benchmarks, then downgrade to 1.34 and re-run them. The question is how to benchmark (re-scanning the library is simple, but not really representative of normal use) - how did you measure the 20% performance gain? I only tested the scan. It's very heavy on database stuff, with a good mix of read and write. When scanning the collection is 20% faster then something has been improved. Either optimized query paths, processing of data, or I/O or whatever. Running this in a loop Code: while true; do ./bench-lms.sh; done puts 100% load on the server and should be fully DB-bound. Agreed, benchmarking is difficult to do correctly. Running this kind of stuff in a loop would likely only hit SQLite's buffer - which is not representative either. In general I've had little reason for complaints with my setup in day-to-day use. But I know that eg. some of Erland's plugins are extremely heavy on database stuff. If you're running one of those, that might be interesting, too. One other reason why I was looking into updating SQLite is that it supports new features in the fulltext indexing I'd like to leverage. -- Michael ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss

I've just updated my LMS to use the latest DBD::sqlite (1.58) and could
run some benchmarks, then downgrade to 1.34 and re-run them.
The question is how to benchmark (re-scanning the library is simple, but
not really representative of normal use) - how did you measure the 20%
performance gain?
Currently, I'm using this script to simulate regular use:
Code:
#!/bin/bash
# adjust genre_id, playlist_id, search term and URL
BCMDS='{"id":1,"method":"slim.request","params":["-", ["playlists", 0, 999]]}
{"id":1,"method":"slim.request","params":["-", ["titles", 0,
99,"tags:acCdefgGiJklnpPDqrROstTuwy"]]}
{"id":1,"method":"slim.request","params":["-", ["albums", 0,
999,"genre_id:771"]]}
{"id":1,"method":"slim.request","params":["-", ["artists", 0,
999,"genre_id:771"]]}
{"id":1,"method":"slim.request","params":["-", ["search", 0,
999,"term:Front"]]}
{"id":1,"method":"slim.request","params":["-", ["playlists", "tracks",
0, 999,"playlist_id:475485", "tags:acCdefgGiJklnpPDqrROstTuwy"]]}'
LCNT=1
TS=$(date +%s.%N)
VERBOSE=1 # 0 to get CSV values
while IFS= read -r line ; do
[ $VERBOSE -ne 0 ] && echo "running query $LCNT"
RES=$(curl -Ss -H "Content-Type: application/json" -X POST -d "${line}"
-o - "http://raspi3-64:9000/jsonrpc.js;)
[ $? -ne 0 ] && echo "curl error:$? " && break
echo "$RES"|grep -q '"result":{"count":0}' && echo "No results for
$line"
LCNT=$((LCNT+1))
done <<< "$BCMDS"
TE=$(date +%s.%N)
RT=$(bc <<< "$TE-$TS")
if [ $VERBOSE -ne 0 ]; then
echo "runtime: $RT"
else
echo "$(date +'%H:%M:%S');$RT"
fi
Running this in a loop
Code:
while true; do ./bench-lms.sh; done
puts 100% load on the server and should be fully DB-bound.

Re: [slim] Why is LMS using such an old SQLite version?
My library is 30k tracks (on a NAS) and the bottleneck is I/O for sure, the SATA died and wiped out the disks, so I rebuilt it with Win7 booting from a USB drive. You're running LMS from a different computer than where the files are saved? This kind of I/O might be the bottleneck during the scan. But I could imagine that when TrackStat is doing its job, it's LMS server side only, no access to the files. I might be wrong. But please double check, because your machine seems more than powerful enough to process 30k tracks. Check the resource monitor while TrackStat is running. Monitor disk, network, cpu and memory usage. It has 8x (i7) CPU cores and 16Gb RAM so is strong Did you check LMS' memory settings for the database? -- Michael ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss

My library is 30k tracks (on a NAS) and the bottleneck is I/O for sure, the SATA died and wiped out the disks, so I rebuilt it with Win7 booting from a USB drive. It has 8x (i7) CPU cores and 16Gb RAM so is strong enough. I can't change the OS due to other software, it works fine day to day but definitely chewing on the db rebuild when Trackstat does a massive update query after a full rescan. So I would like to see if I can play around with the database side of things and happy to share anything useful I find.

Re: [slim] Why is LMS using such an old SQLite version?
Thanks for the research. Long story, short.. my interest is due to a low powered wintel system grinding to a stop when doing a full rescan due to Trackstat. So I was looking at the db and noticed the old version and hence the interest. Is there anyway of decompressing/patching a wintel system to play around with this further? You can run LMS from the source if you're willing to install Activestate Perl 5.14 (which I could provide you a copy if needed). I guess you've already upped the memory parameter for the database? It can make a huge difference (depending on library size, storage type etc.). How large is your library? What is the bottleneck? Memory? CPU? Disk I/O? If you run out of memory, then any other optimization might be irrelevant. Do you know what kind of query it is that plugin is chewing so badly on? -- Michael ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss

Re: [slim] Why is LMS using such an old SQLite version?
Ok, I thought I'd give it the quickest try I could, running a test on my dev machine (2017 MBP, SSD, 16GB RAM).

Now you could say I don't use FTS. But I do. That might show you that a decision pro or con can't easily be taken. Things are a bit more complicated than they might seem.

Re: [slim] Why is LMS using such an old SQLite version?
Is there any reason why LMS is using such an old SQLite version, 3.7.7.1 which dates back to 2011. There are many potential reasons. Call it laziness, or "never touch a running system", or lack of priorities, premature optimization, lack of time... Updating the library for all platforms is virtually impossible. Dealing with the potential issues of running different versions on different platforms might lead to some unwanted decisions (eg. rollback, drop support for some platforms etc.) and certainly would consume considerable amounts of time. Which probably would better be spent elsewhere. Maybe there just isn't any compelling reason to update. Looking through the SQLite release log there seem to be pretty impressive performance gains made over the years so just wondering why this hasn't been rolled into LMS. (DBD-SQLite-1.58 released March 2018) Did you carefully read where those improvements would apply? Does it apply to LMS? Did you confirm it's any faster at all? And where do you see the database as the bottleneck, btw? I'd be happy to see a thorough comparison of current LMS and LMS on latest SQLite, scanning libraries of various sizes (5k, 30k, 100k) on various platforms (Pi, Mac, Windows, desktop Linux). Or at least one of them showing that "impressive performance gain". What would you measure? Scanning time? Browsing performance? Time to playback? PS Can we have the old forum software back.. thanks :p Can it get any older?... it's vbulletin 4, announced in 2009. Its successor v5 was announced in 2012. We never updated beyond security updates. -- Michael ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
