Did you run mysql_init() many times to check this ?  The first
'mysql_init' may be a little bit slower, but after this it should be
REAL fast.

mysql_init() only calls malloc() to allocsome memory.  This should be
real fast.  The only case this may be a little slow is if you have
compiled MySQL with --with-debug and you have much memory in use as in 
this case safe_malloc() will check your memory allocation for
over/under runs

Have you tried 'mysql -A databasename' ?
