Hi, I am really really thankful to all the members of this group. The Discussion here was really very helpful for me and also for the others.
I was not as much experienced as the other members who took part in this dicussion, but i worked hard ad spent a lot of time to find out why i am getting ":memory:" mode slower or sometime no change in results or sometime only little faster may be one second at most. Now I think I am in the position to just leave thinking about to use SQLite in memory mode. I did some tests in the past and also showed results here to you all. in which, memory mode was slower than disk mode. now again i did some tests 1.... Disk mode 2.... Memory mode 3.... ATTACH DB these tests were as I mentioned earlier, tested at Pentium(R) D CPU 3.00GHz 2.00 GB of RAM WINXP Professional. For All these tests I was Using SQLite 3.3.5, but now when I saw that in version 3.3.6 there is some improvement in :memory: then I did some tests again, but the results are not satisfactory. As 'Dennis Cote', 'Joe Wilson', 'Martin' mentioned that "there is another factor at work here", I wish to participate in this discussion but I can't because of my little knowledge about the SQLite working. But I wish, and I hope to find out the way , where we can see a clear difference between DISK and :memory: mode. Dear Dennis Cote, As u suggested me to change my design, so Now I changed it. and its much better now. Again really thanful to to all the members. but if you all think that still there is some way then I will be happy to know about. Regards TAMIMY.
