I have a table with 32 lakh record in it. Table size is nearly 700
MB, and my machine had a 1 GB + 256 MB RAM, i had created the table
space in RAM, and then created this table in this RAM.
So
now everything is in RAM, if i do a count(*) on this table it returns
327600 in 3 seconds, why it is taking 3 seconds ????? because am sure
that no Disk I/O is happening. ( using vmstat i had confirmed, no disk
I/O is happening, swap is also not used )
Any Idea on this ???
I searched a lot in newsgroups ...
can't find relevant things.... ( because everywhere they are speaking
about disk access speed, here i don't want to worry about disk access )
If required i will give more information on this.
