Ning To Jamroom
Hi Tat - Welcome to Jamroom (even though it seems you've been here some time

)
Hopefully some of the other ex-Ningsters here will jump in here and offer advice etc. but I can answer a couple of your questions -
Quote: Are there any modules the you wouldn't recommend for the Home page because of performance issues? Has anyone adder an Image Slider (a la Elastic)?
I'd say that all our modules are ok to load as we are very conscious of performace issues and always create code with that first and foremost. The only module I'd suggest that you would need to be careful of how you use it is the Seamless module. This merges specified lists of JR items into one big list so by necessity does individual database calls to get all initial lists, then sorts, shuffles and orders them which can be a big hit on server resources. I'd recommend using this module to merge no more than 2 or 3 sets of items, and keeping its searches as simple as possible. Also use it no more than once per page.
Quote: I'm also curious about incremental loading. I have seven years worth of information that needs to be cleaned up before I port it all over. I wouldn't mind bringing in the last six months or so just to give me some test data to see how the site fills out. Is this feasible?
There are options in the NingImport module for this. You can set the import for 'no older than' in months. Note that this does not apply to imported members, but you can selectively import active. pending, suspended and left members.
Hope this helps
Paul
