CirrostratusI think you'd need to do some testing to find that out for your particular rules/applications. You can use the timing command to check the average CPU cycles per event: http://devcentral.f5.com/wiki/default.aspx/iRules/timing
I don't know the inner workings for the two commands, but I'd guess that HTTP::path requires at least one more operation than HTTP::uri to parse the path from the URI. If you're checking to see if the path or URI starts with a string, I'd guess HTTP::path and HTTP::uri would take close to the same CPU cycles to do the evaluation (with HTTP::path taking just a bit more CPU time to do the extra operation). If you're doing a "contains" comparison with a URI that contains a query string, then the shorter comparison HTTP::path should be more efficient.
