    Affects Version/s: 1.15

> Results of maxCountExpr and fetchDelayExpr should be stored in memory in Generate

>                 Key: NUTCH-2504
>                 URL: https://issues.apache.org/jira/browse/NUTCH-2504
>             Project: Nutch
>          Issue Type: Improvement
>          Components: generator
>    Affects Versions: 1.15
>            Reporter: Semyon Semyonov
>            Priority: Minor
>
> With NUTCH-2455 the expressions maxCountExpr and fetchDelayExpr are calculated for each value. That slows the process, instead we can store the results for each host in hostDomainCounts. 
> That will take only 2 x sizeof(long) extra memory per host.
