[Maposmatic-dev] SSD performance for osm2pgsql

[Thomas Petazzoni]

Hello,

Sylvain Letuffe has recently reported some benchmarks on the usage of
osm2pgsql on a server using SSD as their storage device. The original
mail, in french, is available at
http://lists.openstreetmap.org/pipermail/talk-fr/2010-May/021293.html.

He had three boxes:

 * Box A, 2 Go RAM, 2 SATA hard-drive in RAID0 10k
 * Box B, 32 Go RAM, 2 SATA hard-drive in RAID0 10k
 * Box C, 8 Go RAM, 2 SATA SSD (Intel SSDSA2M080)

Full Europe import

 * Box A, 7 days
 * Box B, 3 days
 * Box C, 8 hours

Mean duration of the import of minute diffs

 * Box A, 50 seconds
 * Box B, 30 seconds
 * Box C,  3 seconds

When can we get a SSD for the MapOSMatic server ? :-)

Thomas
