I think Alamogul will be a problem on most checkers. I tried with the template script at uncommitted the local finds = PGC_GetFinds line
With the standard fields {'gccode', 'cache_name', 'visitdate', 'visitdate', 'country'} the scripts run out of memory
i 'country' i removed the memory usage is 249,344 kB
But a user with 109.970 is an exception
The global #10 racer2814 with "only" 57804 finds uses 133,376 kB with the same script.
There is probibly no way to write that looks at all caches for the top 10
Racer2814 works fine on the script used in the GCcodes above "Generic streak checker" with a memory usage of 185,856 kB
