Re: No caching - or brutal performance - for repeat queries 4.1.8nt

Well I've tried running under it under 4.0.23 now (believing there might be a 4.1 & Windows 2000 problem) and I've added the server name to hosts and DNS - but I'm still getting no caching - and rediculous (read 5 second +) query response.

Here's what I really don't get. If i run the query from inside the firewall, its fast, fast, fast - If I run outside, the CPU pegs at 100% for up to 5 seconds.

Here is more info and my query ... hope someone out there has a good suggestion...

Ed

My query...

select l.RealtorID1,RealtorID2, Name, Photo, r.Website, r.Email, r.Phone, CompanyID1,CompanyName, CompanyLogo, CompanyID2, c.Phone, c.Website, c.Email, MLSID, l.Description, l.LongDesc, l.Address, Neighbourhood, Town, City, Price,Detail,PictureURL,Type,Category,SubCategory,HouseStyle,Age,Bathrooms,Bedrooms, Fireplace,Air,Pool,Waterfront,Workshop,VirtualTour,TourGraphic from Listings as l, Realtors as r, Company as c where l.CompanyID1 = c.CompanyID and l.RealtorID1 = r.RealtorID and Price >= 425000 and Price <= 500000 and ( City like "%Oakville%" ) and ( Type like "%Single Family%" )

my.ini - note that my server and development environment are behind a firewall. I am packet forwarding port 80 requests through the firewall.
