Wordpress LScache Plugin: TTFB high when enable cache
Last Updated on: Wed, 15 Apr 2026 00:00:02 when i enable cache, TTFB my website increase 1-2s in first visit. Can you help me with that issue? Thank you very much This topic was modified 1 year, 2 months ago by vuthanhcong96. The page I need help with: http://lili.vn Hi, please provide the report number , you can get it in toolbox -> report -> click send to LiteSpeed Best regards, Hi @CacheCrawler , My report number is LWOLAUIB Best regards, Hi, please try the following cases : 1. disable cache plugin , access a page thrice , record the TTFB , calculate the average 2. enable cache plugin , access the same page as 1) , as cache miss , record the TTFB, then purge cache, access again , record the TTFB , repeat this thrice and get average time 3. please export your current setting and reset to default (which I think you are default already , but just give a clean status) , and repeat same process as 2) Best regards, Hi @CacheCrawler , When i take the above your steps, i realize the cause was ESI. If i use shortcode [esi rvx-woo-reviews cache= public ttl= 0 ], TTFB average time is 6.5s, shortcode [rvx-woo-reviews] TTFB is only 5s. Best regards, Hi, yeah well , ESI is like a separated individual request , it also depends on how many times your server takes to process without ESI , its like 1 request only with ESI , it will be 1 main request + 1 sub-ESI-request , so it takes more time.
