Thanks for your prompt response! I am going to try dbcachenowsync.
I did find a way for loading the one million records with speed 100x
faster: that is, using /tmp as database dir. Since Solaris makes
/tmp memory-mapped, it is much faster than a disk-based write. I can
move the database from /tmp to its final drive after completely
loaded. The only problem is that /tmp usually has limited size.
You can increase the size of /tmp by adding in more swap slices (ie swap -a
/dev/dsk/c0t0d0s1). Use "swap -l" to view what it is currently using. Also make
sure that you use a slice that is setup for swapping (wu flag).
