php - Performance issue (caching) - make calculations from the db faster or store them -


the problem changed, core stays same. here problem:

every time user visits page, server pulls data setting table, process php functions , displays result user on html page way: md5(result_string+users_ip_address).

the setting table changed once hour. result, result_string changed once hour.

unfortunately, takes time (10 seconds) result_string because of complicated calculations.

what options display md5(result_string+ip_address) faster user in 10 seconds?

environment: mysql, php.

step 1: create new table or file , save value of result_string in file/db table.

step 2: code updates settings table, append code logic of updating result_string value in file/db table.

step 3: change code fetch values new file/db table.

i've seen in various stackoverflow answers can nth largest element in list doing var nthfromtop = items.orderbydescending().skip(n-1).first(); but wouldn't work if there no duplicates in list? if list contains duplicates, there way nth largest element (or set of elements) using linq? if not, efficient way in c#? to set of items equal nth largest item you'll need group items, order groups, , decrement n group size while n positive. when n reaches zero, you've hit group containing nth largest item. public static ienumerable<t> foo<t>(this ienumerable<t> source, int n) { return source.groupby(x => x) .orderbydescending(group => group.key) .skipwhile(group => { n -= group.count(); return n > 0; }) .first(); }
