Increasing, unbounded memory use when swapout backs up #18

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Whilst trying to model mozilla downloads, with fast LAN clients/servers, the 
memory used by 
Lusca-HEAD used grew unbounded when the disks fell behind in handling swapout 
traffic.

I'm guessing that fwdCheckDeferRead() is running the server traffic at full 
speed because the client-
side is able to sink the traffic quickly.

The change should probably be a twiddle to only allow the swapout offset to 
fall a certain distance 
behind the slowest client, rather than the default behaviour which is "however 
fast it is".

I wonder if this is the same behaviour in Squid-2.HEAD, Squid-2.6/Squid-2.7 and 
Squid-3.x ..
