I recently was dabbling with AskFor() and changing the time waited from 2 minutes to 10 seconds (I think perhaps this value may change in future versions when "network tuning" is implemented).<div><br></div><div>
I noticed that, when used with the -limitfreerelay option that is causes significant increase in traffic between peers. This is because the tx gets asked for (from all connected peers usually), but AlwaysHave never becomes true as it's never stored, always rejected, so it effectively getdatas the transaction from every single connected peer.</div>
<div><br></div><div>Would it perhaps be better to set up a memory pool for rejected txs and blocks (perhaps keeping only the hash) so that these rejected items can continue being ignored?</div><div><br></div><div>I hope these observations are ok - I consider myself at the "trying to understand the code/protocol/algorithm" stage so might sometimes make false assumptions of what the code intends to do.</div>
