Hi

Our site is being optimized right now cause the DB/sql is messed up
The developers of the site are no longer available hence had to give
the DB/sql opti. and on page opti to another vendor.

Now the work is almost complete but db is still suffering there are queries taking lose to 3-7 seconds the vendor is also lost as he has done all the work but not seeing performance.

Also while opti db he was not able to normalize db as not possible to explain DB as no documentation

What can i do need to implement something today very urgent , will sql cache help or how would I normalize ( will that help)

WHAT TO DO
