Unless very poorly written (and I mean VERY poorly written), utilizing iRules should not create poor performance.

Hi ekaleido,

The iRule which I'm going to use will be somewhat similar to below.

when HTTP_REQUEST {
    if { [HTTP::uri] contains "abc" } {
        use pool pool_1
    }else {
        use pool pool_2
    }
}

Will this effect the performance of the device?

Also please note that the iRule for each VIP will be similar to above i.e. each VIP will have a different iRule.
