SharePoint loading time optimization and caching -

we have page in sharepoint list sites, person manages site, contact info, , last modified date.

currently, using custom webpart crawls through sites , reads through metadata, , displays these in list.

opening page takes 10+ seconds.

we're looking @ ways cut time less 3 seconds.

i'm thinking sort of timer job caches page, every half hour, , when page requested, display cached version. data in page doesn't change caching isn't big issue. idea feasible? i'm new in sharepoint steps implement this?

or if there other options/suggestions on how reduce load time, i'm ears.

here approaches might work you.

1. extend existing webpart cache. first user visit site wait long existing solution. fill cache, every other call of site faster http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.webpartpages.webpart.partcachewrite(v=office.15).aspx

2. create timer-job fill da sharepoint- list fields need. render webpart using data. fetch needed data list faster iterating spweb or spsite objects.

3. a lot of data can fetched search-service, , can extend attributes search engine crawl. once search attributes extended can create search driven webpart http://technet.microsoft.com/de-de/library/jj679900(v=office.15).aspx
