  7. Mind your field representations! Sometimes they execute complex DB queries, which behave fine with just a few test records, but become a nightmare with 10000 records. To be sure - test loading a form/list view with 10000 records in the table.

-|| For Variable || A || B (optimized) || Time A || Time B ||
-|| x = Storage(a="abc") || x.a || x!["a"] || 1.064 || 0.39 ||
-|| x = Storage() || x.a = "b" || x!["a"] = "b" || 0.49 || 0.24 ||
-|| row = s3db.pr_person![1] || row!["first_name"] || row.first_name || 0.25 || 4.18 ||
-|| table = s3db.pr_person || "first_name" in table || hasattr(table, "first_name") || 0.74 || 0.42 ||
-|| table = s3db.pr_person || "first_name" in table || table.first_name || 0.74 || 0.27 ||
