Just a note to hopefully help someone else out. I have been running VirtualBox on my sager laptop inside zfs partition with 2Gbytes of ram build 82. Even though I had the Guest OS set to 600Meg. (WindowsXP) MY memory would keep dropping until I started seeing performance problems. I added another 2Gbyte of ram to the system but this only delayed the performance problem. I thought that it might have been a memory leak with VirtualBox but the process memory usage never grew.
I found the problem to be zfs cache. I believe this was caused by the large file size of VirtualBox and that ZFS cache keeps trying to bring it into memory. I have limited zfs cache down to 1Gbyte using the following line in /etc/system set zfs:zfs_arc_max = 0x3E800000 The performance problems went away and VirtualBox is still happy. Hope this is help to someone. This message posted from opensolaris.org _______________________________________________ opensolaris-discuss mailing list [email protected]
