I asked about slow indexing in RSQLite for a genetic database.  Seth Falcon's 
suggestion of making sure that the identifiers were stored as integer rather 
than string made a big difference.  SNPs come from the factory as "rs100092" 
and stripping the "rs" off the front is easy.

Other advice about larger or smaller SQLite cache size didn't seem to have much 
impact in my setting, and I didn't try the advice about getting a different 
database.

Despite it's many other virtues, SQLite is still slow at indexing.

Thanks to all.
