Site performance, Server errors, outages and tunings

New HHVM version came first 😉 Let's see if there are any differences.

The error disappears for me after some time. It mostly helps visiting another thread and coming back to the one that gave the bug.
I can live with this, but I think you have a high standard of quality and you have difficulties knowing there are faults in your forums.

Edit: That last remark is something we appreciate heavily

The problem is - I can't reproduce the problem. I do have "the server is busy" errors from time to time, that I can explain , but I never see "the garbage".

And yes, I would like to have everything faultlessly working. And fast 😉

Just rebooted the server to completely clean up all the caches.

Ha! After the reboot(and cache cleaning) Apache stopped compressing images! So, my config works!

New HHVM 3.10.0 crashes a bit too often 😕

HHVM keeps crashing. I dug into the code and replaced one function (HHVM chokes on) with the original PHP function. Let's see what happens. BTW, on the HHVM forum people ask how to revert back to the previous version (it's not that easy). There is definitely something wrong with 3.10.0, and it eats more CPU cycles.

No crashes since I changed the code. Let's see what happens overnight.

Also, I tweaked the slideshow plugin (highslide):

o- reduced CSS from 21K to 6K
o- changed the config (the slideshow controls are now underneath the image)
o- changed the CSS/JS loading logic, so no separate calls are made to get the extra files.

... and optimized the Blog code

o- No lazy load for the permanent header images (what removed image flickering)
o- Replaced some images with CSS

Took me two days 😁 At least the page load statistics and browser caching look much better.


Next step is to upgrade 3 more plugins and look into the youtube embedding code. It looks terrible in the web-page metrics.

Another thing - there is no support for MyBB 1.6 anymore. I'm soooooo glad I dared to upgrade to 1.8 a year ago! 😉

BTW, @madjack, @herrpee, @MstrChain : do you still see the garbage?

[herrpee]

will keep you posted if I encounter it
