Hi Mike,

After some experimenting on a WAN network I discovered that opening lot's of tables resulted in very poor performance. It seemed to be that small tables ( smaller than a few kb) loaded faster (with either the USE statement as loading with the dataenvironment) than longer tables.

On my 128 kb WAN some tables took about one or two seconds to open and other larger tables took about 8 to 11 seconds to open. I concluded that VFP buffers a portion of the table when opening the table which is slowing things down.

I also came to the conclusion that many of the poor performance of form instantiation cases might be due this buffering mechanism.

No my question is, is there any way to have control over the amount of data VFP buffers when opening the table? If not I'd like to adress this point as a ER. I really think that such an mechanism could optimize many performance problems (on a WAN and even over a LAN network) when opening tables.

Regards,
Walter,
