I already make that kind of script for my client, but let me explain very clearly that its not depend on script that fetch 100000 data in one minute, but its all depend on server where its run, and most impotent its depend on Internet speed on server, some web hosting block that kind of script, if you have very strong internet then its possible, but if some one said that he can make script which can run on simple internet and it can grab 100000 result so its all fake,
You need very strong Internet pipe line for that , because script run on internet , if it have about 40 to 50 mb per second so it can fetch result. but i can give you maximum results. lets talk in detail
