Currently I run MCF1.1dev on MySql 5.5.
I am thinking to try having the "jobqueue" and "ingeststatus" table on  MEMORY instead of Innodb, to see how fast MCF can run to crawl files using Windows share connection. 

I figured the "ingeststatus" table contains huge data as the "lastversion" column  seems to contain all sids and a file path. 

What is the ingeststaus table used for?
