We tried using MergeFactor setting but out CPU Load/Slow Query time issues were more widespread, optimizing the index always alleviated the issue that is why we are using it now. Our index is 2 GB when optimized and would balloon to over 4 GB so we thought the issue was it was getting too big.
I notice a small spike in CPU load after every replication but then after a couple of seconds load returns to normal (which is less that 25%) it is just sometimes (once in the last week) that it would spike and stay high (10 minutes) until I optimized the index. Before I would optimize the index after every commit the issue would occur more often. We would like to not optimize and use the built in Merging but we had before and the issue would occur more often. We were thinking of trying a mergefactor of 2 again but I'm afraid this issues will return. I installed SPM and am monitoring it to see if it tells me anything, I can post the results on Monday and hopefully it will tell us something. At this time we aren't warming and caches, we weren't sure if this was an issue because our slowdowns weren't happening every time. Also, we are using the join functionality of Solr 4 if that helps.
