In case you are running Hypertable v0.9.2.2/v0.9.2.3 without installing tcmalloc, it is strongly recommended that you add the following parameter to your configuration:
Hypertable.RangeServer.AccessGroup.CellCache.PageSize=512K We have observed that on some systems Hypertable is consuming way more memory than it needs to owing to a glibc malloc heap fragmentation issue described here: http://lwn.net/Articles/249113/ http://blogs.gnome.org/alexl/2009/02/17/eternal-vigilance/ The memory usage goes down drastically with the PageSize parameter set to 512K instead of the current default 100K. In future releases the default will be set to 512K. In case your Hypertable installation uses tcmalloc (as recommended in the Hypertable install instructions) this should not be a problem and consequently you don't need to change your configuration. -Sanjit --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Hypertable Development" group.
