      WT_BTREE_READONLY is unlikely to be true in ASC. Therefore, we should swap the two checks here to reduce the perf impact on ASC:

              /* Skip read-only btrees if we are not looking for clean pages. */
        if (!F_ISSET(evict, WT_EVICT_CACHE_CLEAN) && F_ISSET(btree, WT_BTREE_READONLY)) {
            WT_STAT_CONN_INCR(session, eviction_server_skip_trees_read_only);
            continue;
        }
