<div dir="ltr"><div dir="ltr">Hello everybody.<div><br></div><div>I have this weird issue with Varnish 5.0.0 on Debian 9.4 and maybe somebody here can help me with it.</div><div><br></div><div>The thing is, I have this request:</div><div><br></div><div><a href="https://somehost.com//cart/current_cart.json?clear_cart=false&_=1550491039254">https://somehost.com//cart/current_cart.json?clear_cart=false&_=1550491039254</a><br clear="all"><div><br></div><div>It is always a miss in varnish (as it should be) and making only one, works just fine.</div><div><br></div><div>But doing some performance testing the response times increases quickly. For example, with 2 requests/s, after 4 or 5 request, the response time begins to increase exponentially and after 20 request I have 11s of latency, reaching 40s after 40 requests.</div><div><br></div><div>If I take out Varnish (sending the request from nginx to the app) it works just fine. And looking at the varnish log, the "%T" format option in the backend log keeps a response <=1s but in the client side I see the incremental reponse times.</div><div><br></div><div>The request can't be cached so now I am keeping it out from varnish but I don't like the idea of this exception in the configuration and I am worry it could reproduce with other requests (in fact I have two other suspects) so any idea or suggestion will be greatly appreciated.</div><div><br></div><div>Thanks for your time.</div><div><br></div><div><br></div>-- <br><div dir="ltr" class="gmail_signature">Rodrigo García Suárez<br><a href="mailto:rodrigo.garcia@the-cocktail.com" target="_blank">rodrigo.garcia@the-cocktail.com</a><br>679 141 132<br><br>The Cocktail<br>c/ Salamanca 17<br>28020 Madrid<br>(+34) 915 670 605<br><br>www > <a href="http://the-cocktail.com" target="_blank">http://the-cocktail.com</a></div></div></div></div>
