Subject: Performance on PowerQuicc8280 linux based
Date: Wed, 15 Nov 2006 15:54:51 +0100 [thread overview]
Message-ID: <6e41d1460611150654j6e532ae1pbe378685539e257e@mail.gmail.com> (raw)
I've a system Linux based on ppc8280 platform with unstable
performance from a compiling to another.
I've a board with 2 Ethernet interfaces and I inject traffic in one of
this and analyze the number of packets that I receive in the other
one.
I obtained 60000 pkt/s the first time, the second time i recompiling
the kernel just changing some died function that is not involved in
the flow of the packet.In that case I obtained 47000 pkt/s and it
seems that moving code position change the behaviour in term of cache
functionality.
Could someone help me to understand this strange situation
Regards
Aldo
