|Title||AMC now slower than 1.113|
|Assigned user||David Lovemore|
|Description||During release testing, we found that gcbench was running slower for AMC than in version 1.113.|
|Analysis||See  for analysis. In summary the ChainDeferral used to only test generation 0. Generation 1 wouldn't get collected when it was full, but would get collected the next time generation 0 filled up. This meant that generation 1 was effectively larger, but less well regulated.|
The fix is to add half generation 0's size to generation 1, and recommend retuning of chain parameters.
