So How Fast is an APR Hash Table?

Just ran a quick metric on uploading approx 20K stock information items into an APR hash table on a heavily loaded (load avg ~4), Sparc III based Solaris 8 machine. It took 32ms to load which works out roughly 1 microsec per apr_hash_set() call. Each data item was roughly 140 bytes long - not bad for an old machine.
