In December 2009, Germany’s Talentraspel virtual worlds Ltd. set a world record by squeezing 500,000 prims into one OpenSim region. That record stood for two and a half years until Ener Hax decided to see if she could beat it — and was quickly followed by OSGrid president Michael Emory Cerquoni — also known as Nebadon Izumi in-world — who set a new world record by putting a million cubes on a single OpenSim region.
Well, the Germans have taken the title back.
Bernd Beyers, co-founder of the Metropolis Grid, in Constance, Germany, announced to Hypergrid Business today that he had reached the 2 million mark — and using prims, not mesh objects.

Beyers said he used the latest 0.7.4 development version of OpenSim, on an AMD Octa-Core machine with 2.4GHz, 24GB DDR3-RAM, Raid1-HDD, running Debian 6 64Bit Linux and Mono 2.10.2 to run the region server.
He used the Hippo 0.6.3 viewer on a separate Windows Vista machine to visit the region. The computer was an Intel Core Duo 2GHZ, 2GB-RAM, ATI Radeon XPRESS 200M 512MB.
“IÂ used a modified Hippo OpenSim viewer with a draw distance of five meters,” he added.
The final count of prims was 2,008,590, in sets of 2,000 hand-placed groups.
“First I pushed the objects to 2,500,000 cached prims but after a reboot 500,000 prims had been lost,” he said. “In my opinion the database was not able to store the last 500.000 prims because it had no RAM memory left to work with.”

After the sim restart, only 2,008,590 prim cubes were left on the region, with a loading time of just over 12 minutes.
“OpenSim performed well,” he said. “A big thanks to the developers — they did a really good job.”
