h-y-b-r-i-d Posted November 16, 2015 Posted November 16, 2015 A fresh IPS4 setup seems to have a rather large time to first byte. I have a dedi, optimized php and apache setup. 4 cores, plenty of RAM. SSD drives. Zend opcode/memcached etc being tested from a few miles away. Server in London, test from London. The TTFB is ~ 1 second. This is abnormal and normally caused by server spec or DB bottlenecks. Server is good. Invisions own site has the same issue when tested. Other forum software responds in ~300 when tested on same server. Is this something you are aware of and would look into improving?

One trap many fall into is installing a few different caches. Don't. Zend opcache is very good in PHP 5.5+. Try using a cloud service. They will also do some caching, but on their side.
h-y-b-r-i-d Posted November 16, 2015 Author Posted November 16, 2015 The do different things Zend opcode/memcached both is fine as far as I am aware.

Opcache and Memcached are two very different things.
h-y-b-r-i-d Posted November 16, 2015 Author Posted November 16, 2015 Anyone had much luck using innodb?

h-y-b-r-i-d Posted November 16, 2015 Author Posted November 16, 2015 Yeah, I read that back in 2012. I dont consider it meaningless. Further, that is CloudFlare making excuses for their own setup. The server I am testing is not on CloudFlare, so it isn't relevant. Thanks.
CheersnGears Posted November 16, 2015 Posted November 16, 2015 1 minute ago, Paul.F said: https://blog.cloudflare.com/ttfb-time-to-first-byte-considered-meaningles/ It's not meaningless if Google says it's not meaningless. While I agree with the idea of not obsessing over small changes in TTFB, there is a large difference in TTFB between IPS and other heavy PHP software on the same server.
sasiko Posted November 16, 2015 Posted November 16, 2015 i wonder if php 7 would have any significant impact on TTFB along with httpd 2.0 Anyone wanna do comparison test? :D

Unfortunately I cannot do a comparison test due to having sucuri in the middle which also affects TTFB :/ Might consider turning it off for a test but not sure yet.
Ahmad E. Posted November 16, 2015 Posted November 16, 2015 40 minutes ago, maidos said: so your server is using httpd 2 aswell? Yes but since sucuri only supports SPDY it will be served through that unless you bypass sucuri (which I do). Edit: tested it using webpagetest without having sucuri in the middle, TTFB is 0.500-0.630 seconds (php7 + http/2)
TSP Posted November 16, 2015 Posted November 16, 2015 Yeah, the increase in average server execution time from IPS 3.4 to 4.0 is quite bad at the moment I'll give you a guess on when the community that this chart belongs to was upgraded: (October 28 is the answer) I've tracked some of it down to slow queries. But a big part of it seems to be a general significant increase in the execution of the "framework basics" itself. It seems a "fast" page load is now done in approximately a second, while a fast page load in 3.4 was done in 0.25 seconds. I know 4.1 will bring some improvements, but due to various factors I'm unable to do that upgrade in the immediate future. Still, I suspect 4.1 will still be far from as fast as we had 3.4 running.
h-y-b-r-i-d Posted November 16, 2015 Author Posted November 16, 2015 From some inital testing it does appear that it could be related to opening like 14 connections for the css and js. 2 would be better. 4 even. But 14?
sasiko Posted November 16, 2015 Posted November 16, 2015 can we get any comment regarding minimizing amount of css and js?

But 14? This has nothing to do with the server response time for the initial document (or first byte delivered). Server response time is basically the time it takes for index.php to deliver the HTML-document that tells you to load 14 CSS/JS.

First site in my sig is running under it (actually they all are, but only the first one is an IPS site). It's not busy since it's a new'ish site and it's a very limited target market.
sobrenome Posted November 17, 2015 Posted November 17, 2015 I was told to move to MariaDB with XtraDB (InnoDB) for better performance. I have no comparison data, but I was convinced at the time by some technological arguments in favor of MariaDB with XtraDB.
sudo Posted November 17, 2015 Posted November 17, 2015 16 hours ago, DealTrakr said: Anyone had much luck using innodb? You should use innodb but along with MySQL 5.6 or a later MariaDB version as older versions as considered much slower with InnoDB.
Lab Rats Rule Posted November 17, 2015 Posted November 17, 2015 You know I did some testing and gzip did a much better job then memcached. Try it... Server settings for this and pigz may make a difference also. But here is my cpanel optimize configuration for now. Adding images adversely impacted page load time a lot. application/x-javascript application/javascript application/xhtml+xml text/html text/xml text/css text/javascript Keep alive also decreased my page load time by 85% for my older version site. And made my 4.1 site 2.5 times as fast. A ctrl f5 loads my graphic intense and heavily modded older version with VPAID, animated and enhanced ads in 1.5 seconds. My 4.1 with the same ads loads in 1.75 seconds.

It also seems once you run >5.6 with innodb there is no going back to a lessor version.. So if anyone switches servers afterwords, you have to have >5.6.
h-y-b-r-i-d Posted November 17, 2015 Author Posted November 17, 2015 Running innodb now on mysql 5.6. Seems quicker. Still a cold first page load has some large TTFB. Have keepalive and gzip enabled anyway. Will try MariaDB over the weekend I think if it's worth it?

h-y-b-r-i-d Posted November 17, 2015 Author Posted November 17, 2015 I do, but if you have any recomendations Thank you!
