Background

Benchmarks of osm2pgsql are important metrics for users to reference because importing OSM data is highly dependent on machine hardware and software configurations. Importing a complete planet file can take days even on a typical higher end desktop machine. Importing an extract(subset) of the planet file can take considerably less time to import and should be used if possible for your import instead of the planet file.

What affects import time?

Partial list of variables that affect the time it takes to import.

  • Hardware
    • Hard disk throughput ( HDD, SSD )
    • RAM size
    • CPU
  • Operating system
    • OS used and 32 bit or 64 bit version
    • linux disk scheduler ( CFG, noop, deadline, ... )
    • linux file system ( ext4/LVM , xfs/raid, ...)
  • Database
    • Version
      • PostgreSQL 8.2 and PostGIS 1.5
      • PostgreSQL 9.1 and PostGIS 2.0
      • PostgreSQL 9.2 and PostGIS 2.1
      • ...
    • PostgreSQL config settings ( postgresql.conf )
      • shared_buffers
      • work_mem
      • maintanance_work_mem
      • synchronous_commits
      • fsync
      • autovacuum
      • checkpoint_segments
      • ...
  • Osm2pgsql application
    • osm2pgsql version ( 32bit, 64bit )
    • parameters
      • "Slim Mode" or not
      • Size of the node cache (-C command line argument)
      • Flat node storage
      • Hstore / style
      • Parallelisation ( --number-processes )
  • Use case
    • size of the import file : Full planet or Extracts
    • input reader and input file format
      • the experimental 'primitive' XML parser reads OSM XML input about 30% faster than the default 'libxml2' reader (but seams it currently as a bug in supporting some xml entities such as ' )
      • the 'pbf' input reader reads OSM PBF files about twice as fast as the 'libxml2' parser parses an equivalent OSM XML file
    • other customisation ( special index )

Example Output

The following is sample output generated while importing a planet file using osm2pgsql for reference. The linux time command was used in this example to output the amount of time it took for osm2pgsql to finish. Note the NOTICE lines are normal when importing into an empty database.

Explanation and progressbar

If you want to know how far the import has gone, see the statistics and compare it with "Processing: Node" section of the output. Note that processing relation takes approximately 10 times as processing a way (which takes approximately 10 times processing a node). In my case, nodes were processed at 40.8k/s, ways at 0.13k/s and relations at ..k/s. Also, closing a table take approximately as long as importing the data. So if you finished importing the nodes, you are roughly 1/6 into total import.

Benchmarks

List of benchmarks contributed by users. Currently simply using time command to return length of time' it takes osm2pgsql task to complete. If you do not have time available please provide some other meaningful metric. Better organization and formatting standard for this section is needed.

Update performance osm2pgsql classic vs. persistent node cache

While import performance was of great importance when it took weeks, today it is really more interesting to improve the time it takes to catch up and update the database. For example in the above example it takes 24 hours to import and much longer to catch up with the current diffs. Even assuming a planet dump can be downloaded in a couple of hours, an installation will have to catch up at least the 3 days it takes to actually produce the dump. Further experience shows that rendering and updating tend to impact eachother leading to installations falling substantially behind over time.

Kai Krüger has added an experimental "persistent" node cache mode to osm2pgsql that promises some improvements. To see if this is actually the case I ran a further import on above HW with the persitent node cache enabled and updated the DB for a while.

Results for 15x6h updates starting 1st August 2012:

osm2pgsql classic: 36 hours

osm2pgsql experimental: 27.7 hours

Notes:

  • in both cases osm2pgsql was ran with -number-processes 1, both numbers would be substantially lower if ran with more parallel processes however there is currently an issue with this with the persistent node cache. Note this issue has been fixed in the mean time.
  • not all 6h updates showed the same performance gains, this probably warrants further investigation.
  • no significant difference in import time.

As a further comparision numbers from the fastet installation I currently have ( Intel E5-1650): 4.8h

Planet import on custom E5-1650 (32GB RAM - 6 cores)

  • Intel E5-1650
  • 32GB ECC RAM
  • Supermicro X9SRA motherboard
  • Ubuntu 12.04 LTS
  • PostgreSQL 9.1 (note: these settings are for import only)
    • shared_buffers = 4GB
    • work_mem = 100MB
    • effective_io_concurrency = 2
    • fsync = off (import only!)
    • synchronous_commit = off
    • full_page_writes = off
    • checkpoint_segments = 100
    • checkpoint_completion_target = 0.9
    • autovacuum = off (import only!)
  • Kai Krüger tile server packages
  • osm2pgsql SVN version 0.80.0 (64bit id space)
  • Planet from 2012-07-04
  • 1 x Intel 520 120GB SSD - / (OS etc)
  • 1 x OCZ Agility 3 240GB SSD - rendering database without slim tables
  • 2 x WD VelociRaptor WD1000DHTZ, 10'000rpm, 64MB, 1TB, SATA-3 in software RAID 1 - pg_xlog, slim tables and indices
  • 2 x Seagate Barracuda 3TB, 7200rpm, 64MB, 3TB, SATA-3 in software RAID 1
  • Notes:
    • using the deadline I/O scheduler on the SSD has no apparent effect in Ubuntu 12.04
    • if you don't want or need ECC support, a core i7 39xx processor will give the same performance with substantially cheaper memory. For example a Hetzner EX10 with a 240GB SSD should give even better performance (due to more memory).
    • increasing maintenance_work_mem over 4GB had no significant effect, except that with 16GB the import process became very slow.

Osm2pgsql took 152995s overall (45.5 hours)

NOTES:

  • I had to use osm2pgsql 0.81 as the current git version (0.85) crashed while processing relations (twice)
  • I also upgraded libgoes from 3.2.2 to 3.3.9 while attempting to fix the above crash. It didn't fix it, but I stuck with the new version.
  • The parallels image file grew to 414GB. My '410GB' expanding drive was 98% full at the end. I would recommend making your drive as big as possible.
  • My mac actually ran out of space about 30 hours in (though the VM drive thought it had more space because parallels allows you to make expanding drives as big as you like). Thankfully the VM paused while I freed up more space and didn't crash the import process

  • Conclusions
    • 2 x 512GB was enough for full planet import using -slim and unlogged tables, import time about 12 hours with full planet
    • for updatable database it was too much tablespace shuffling
    • additional 1TB SSD was finally working with continuous updates
    • for updates osmosis + osm2pgsql is used
    • catching up 6 days took about 6 hours, minutly updates 2-20 seconds (depending on count and size on changesets)
    • PostgreSQL settings are working well, but it is bound to the hardware in use (DONT copy & paste blindly!)
    • unsure if the parallel settings had positive effect
    • flat nodes files best kept on fastest disk
    • if import is interrupted, not all is lost. If it happens during index generation, you can manually create indexes.

I see ~2000Knode/s, 0.4Kway/sec , estimated time till ways finished is 2 wks, if relations speed is ~1/10 ways speed then a few hrs for relations, if closing db is ~ same time as building then another 2 wks.

I imagine that some of the import is nonlinear in number of nodes/ways/relations but am not versed in the mysteries; however if this is the case, then size of db is even more important to report ; in such a case, Kways/s for given hardware will not be constant for different sized dbs.

Import took about 14 hours using flat-nodes (flat node file on ssd), max mem used: 160GB while building indexes. The flat node file never grew bigger as 48GB. Planet download was about ~ 44 GB, postgres db size is now roughly 670GB.

debian 9 / openstreetmap-tile-server

Import is based on docker "openstreetmap-tile-server" (https://github.com/Overv/openstreetmap-tile-server)

with minor adaptations for import of slim planet. (https://github.com/stevo01/openstreetmap-tile-server/tree/dev-stevo 307294b)

Hardware

  • SSD Samsung EVO 2TB / ext4
  • 64 GByte (none ECC)
  • AMD Ryzen 7 1700 Eight-Core Processor

Operating system

  • Debian GNU/Linux 9 64bit
  • Docker version 18.09.4

Database

  • PostgreSQL 10 and PostGIS 2.4

Osm2pgsql application

  • osm2pgsql version 0.96.0 (64 bit id space)

Use case
