Title: Should I decrease max TTL? Last modified: January 10, 2021 --- # Should I decrease max TTL? * Resolved [radorp2p](https://wordpress.org/support/users/radorp2p/) * (@radorp2p) * [5 years, 3 months ago](https://wordpress.org/support/topic/should-i-decrease-max-ttl/) * I currently have a max TTL of a week. When I check Redis stats, used memory is around 20mb while max memory is 122mb (128mb). Based on this, should I decrease my TTL? How does it affect performance?

Should I increase or decrease max TTL? * Plugin Author [Till Krüss](https://wordpress.org/support/users/tillkruess/) * (@tillkruess) * [5 years, 2 months ago](https://wordpress.org/support/topic/should-i-decrease-max-ttl/#post-13893147) * You can increase it if you want and see what happens. * Thread Starter [radorp2p](https://wordpress.org/support/users/radorp2p/) * (@radorp2p) * [5 years, 2 months ago](https://wordpress.org/support/topic/should-i-decrease-max-ttl/#post-13897432) * Thanks. Last question: If I lower my 604800 max TTL to 86400, would it improve or worsen page load time / performance? * Plugin Author [Till Krüss](https://wordpress.org/support/users/tillkruess/) * (@tillkruess) * [5 years, 2 months ago](https://wordpress.org/support/topic/should-i-decrease-max-ttl/#post-13898314) * That depends on your traffic. Likely no difference. Play with it. * Thread Starter [radorp2p](https://wordpress.org/support/users/radorp2p/) * (@radorp2p) * [5 years, 2 months ago](https://wordpress.org/support/topic/should-i-decrease-max-ttl/#post-13899047) * I have around 10k daily traffic. Should I use low or high max TTL? I could not really find any explanatory information on max TTL. * Plugin Author [Till Krüss](https://wordpress.org/support/users/tillkruess/) * (@tillkruess) * [5 years, 2 months ago](https://wordpress.org/support/topic/should-i-decrease-max-ttl/#post-13899750) * You’ll have to find the ideal configuration yourself based on your Redis Server max memory. * Thread Starter [radorp2p](https://wordpress.org/support/users/radorp2p/) * (@radorp2p) * [5 years, 2 months ago](https://wordpress.org/support/topic/should-i-decrease-max-ttl/#post-13903245) * You never give a clear answer lol * Plugin Author [Till Krüss](https://wordpress.org/support/users/tillkruess/) * (@tillkruess) * [5 years, 2 months ago](https://wordpress.org/support/topic/should-i-decrease-max-ttl/#post-13903639) * MaxTTL is highly dependent on your setup, I can’t provide you with a clear answer. * Thread Starter [radorp2p](https://wordpress.org/support/users/radorp2p/) * (@radorp2p) * [5 years, 2 months ago](https://wordpress.org/support/topic/should-i-decrease-max-ttl/#post-13904486) * It was like this: When my max TTL was 604800. * # Memory used_memory:19640320 used_memory_human:18.73M used_memory_rss:13844480 used_memory_rss_human:13.20M used_memory_peak:30129928 used_memory_peak_human: 28.73M used_memory_peak_perc:65.19% used_memory_overhead:1732654 used_memory_startup: 796328 used_memory_dataset:17907666 used_memory_dataset_perc:95.03% allocator_allocated: 19988296 allocator_active:21180416 allocator_resident:26193920 total_system_memory: 1029038080 total_system_memory_human:981.37M used_memory_lua:41984 used_memory_lua_human: 41.00K used_memory_scripts:0 used_memory_scripts_human:0B number_of_cached_scripts: 0 maxmemory:128000000 maxmemory_human:122.07M maxmemory_policy:allkeys-lfu allocator_frag_ratio: 1.06 allocator_frag_bytes:1192120 allocator_rss_ratio:1.24 allocator_rss_bytes: 5013504 rss_overhead_ratio:0.53 rss_overhead_bytes:-12349440 mem_fragmentation_ratio: 0.71 mem_fragmentation_bytes:-5753840 mem_not_counted_for_evict:0 mem_replication_backlog: 0 mem_clients_slaves:0 mem_clients_normal:49694 mem_aof_buffer:0 mem_allocator: jemalloc-5.2.1 active_defrag_running:0 lazyfree_pending_objects:0 * Thread Starter [radorp2p](https://wordpress.org/support/users/radorp2p/) * (@radorp2p) * [5 years, 2 months ago](https://wordpress.org/support/topic/should-i-decrease-max-ttl/#post-13904561) * There is also 2gb swap memory.
