Is Fedora Core slower than RH 9 ?

[R. S. Patil]

Dear Friends,

I have Both RH 9 and Fedora  3  with me.

I tried First RH 9 on a PII M/C with 128 MB RAM.
I Ran Test application using FB 1.5 and D5 Client Appplication
The longest Procedure in that application was test Case
It took 15 Min on RH 9.

On same M/C I installed FC3 and same application setup was  done.
same Test procedure was run on new config,
It took 55/60 Mins.

I am surprised since My expectation was it should take either less or
similar time.

Can some body tell me what might have gone wrong ?
Are there any config issues with FC3 ?

Thanks
