Some years ago (mmmm... probably around DOS 5.0 :) it was worthwhile to open tables readonly, because it sped up the network access significantly. The network would know that these file handles are not a source of locking, so a lot of checks were dropped and it did go visibly faster. Helped with the reports a lot.

So, I'd like an update - is it still so, or are today's networks smart enough with locking to the point where opening tables readonly doesn't matter much?
