@elek , whatever tests we conducted(using teragen for runs > 100GB), we never changed this limit. Also, it was observed that the queue used to hold the pending task in the write chunk executor used to fill up fast thereby indicating all the threads being busy actually doing write chunk. Though 60 may not be the ideal value, but i would still prefer to do some similar tests before changing the default here.
