This is my setup:
2xSQL, 2xAPP, 2xWFE where;
SQLs is 16GB ram
APPs are 12GB ram
WFEs are 12GB ram
Search is running on one of the APP servers, and Requests are on the other. I have a combined DB size of 700GB.
So, first time, Full Crawl was running for 30h, indexed around 1.6mill documents. After the Full Crawl the Incremental Crawl started and it ran for 29h, a second Incremental Crawl startede and i stopped it after 10h, because those times did not seem right to me.
Even the MySites that is in a own WebApp and a own Content Source ran for 2h Full Crawl.
Im not that strong in Search, but I discovered that my initial configuration was downgraded to:
- APPs 5GB ram
- WFEs 4GB ram
So could this have been the issue for the slow times? The small amount of RAM, and waht about the drive space? When it crawls the C drive only has around 10GB free, could the drive place also bottleneck something?
I have asked them to roll the configuration back to the inital, and size the drives so the C is minimum 80GB and the Index is 20 procent of the combined DB size, that is 140GB.
What else should I look into? Could this be suficient enough to solve the Crawl issue?
I am still waiting on the server-team to upgrade the config, before I can test again.
