Multipath and NetFlow Relationship !

Question

Is it normal for netflow to have negative effect on multipath application?

I've been trying everything since morning, suspecting the cables. because even if multipath works, it uses half the bandwidth of 2 lines in total. So i thought the cables were getting stale. Even though I saw a 1gbit lan connection, I was getting a maximum speed of 100-120mbit.

50/100 mbit/s for 1st line
50/100 mbit/s for 2. line at maximum.

I removed the netflow entries as a last try. I got full efficiency from 2 wan connections again.

no ip flow-export destination 
no interface DSL ip flow
no interface ISP ip flow
system configuration save

I read somewhere that netflow affects hardware and software accelerators. Is it true?

in addition, multipath is working normal on wifi devices while netflow is active. is this also interesting?
