We continue to run on Fetcher1.

Since you're running large crawls, could you run one of them with Fetcher2 and comment on the results? Note that Fetcher2 needs a lot fewer threads than Fetcher - usually running a large crawl with < 100 threads is more than sufficient.

Excellent about time to run another large fetch so will try it.

Also, note that the default settings prefer the old Fetcher, specifically:

* fetcher.threads.fetch - the old Fetcher would slowly run out of free threads at the end of the job, so you needed more threads to compensate for that. Fetcher2 doesn't have this problem, so reduce this number accordingly.

* turn off parsing in Fetcher - this is best done in a separate job anyway.

* set generate.max.per.host.by.ip and fetcher.threads.per.host.by.ip to the same value - they are different by default. IMHO this value should be false.
