Problems using IB and Banca Sella

Hi all,
sry for my english not that good, I try to explain my problem:
trading futures
chart 1 use IB as datafeed AND as broker with strategy X;
chart 2 use Banca Sella as datafeed AND as broker with same strategy X;
if I attach Autotrading in one OR the other chart everything works fine,
if I attach Autotrading in BOTH charts then IB always works fine while when there's a spike in volumes Banca Sella slow down and loose a lot of movements in the chart although in the Trade Bar the prices are correct.
I know that while IB pass ticks only if the price differ from the precedent one, Banca Sella pass every single tick but don't think this matter.
Opening or not opening others charts doesn't change the situation.
My pc is a new one, doesn't have problems to manage the flow so it is not an hardware problem.
What could I do to solve this problem?
Any suggestion ?
Tks for your attention.
