For over a year I have been struggling with the response speed on my Drupal v7.2x CMS install. Let me explain. I'm running Drupal 7.2x on an Ubuntu 12.10 (upgrade to 13.xx pending) for the purpose of webdev projects for pure Drupal CMS (though Symfony may follow also later).
I have never installed Xammp or any similar web services preferring to run on localhost with the LAMP (Apache etc) included with the Ubuntu install. It is becoming impossible to make even the smallest changes as the whole process seems to take the best part of 1-3 mins to write to the CMS and though I have persevered, it's become a serious pain!
I have asked similar on other stack exchanges I'm on with no real answer given (other than get a faster machine! It's the second one and it's a good spec machine..running PURELY Ubuntu and is not shared with any other OS). I have done all the normal things, cache clearings, reduction on logs and turned on/off every possible option 'button' in the backend of Drupal config. I want to stay with the Drupal framework.
The machine is my primary home workstation which I use for the normal 'everyday' things; browsing web, WebDev, Office etc and I installed the Ubuntu desktop.
To this some have said I should really go for a 'server' box, others has said that it could be I need something like Nginx; some have said it could be a DNS issue, which I have not implemented for fear of 'ballsing' up my current projects LOL, but the speed of re-writes takes ages and I really need some quality advice on what is happening behind the Linux scenes and how I can overcome these problems. I would prefer to stay with one single desktop workstation box as this helps my everyday working and simplifies my uploads to any future live sites to my webspace provider.
MAY I ALSO ADD: that whilst the page load/write is taking place during this slow period there is a significant amount of HD activity* as if data is being accessed, unlike a normal write (*of course this happens as part of data access, but not as massive as it happens here!) :-)
Edit (amend from my Comments):
The computer is an AMD X2 (3.2Ghz) 260; 16G Ram, Gigabyte (GA-MA68MT-D3P) Mobo, 3*500Gig HDs. 2*20" LCDs. I'll see if I can view System output.
I'm using mySQL (see below) but whilst I'm open to learning, I'm a bit wet across all areas (-: Server:Localhost via UNIX socket Server version: 5.5.32-0ubuntu0.12.10.1 Protocol version: 10 User: paulb@localhost MySQL charset: UTF-8 Unicode (utf8) Web server Apache/2.2.22 (Ubuntu) MySQL client version: 5.5.32 PHP extension: mysqli Documentation
May I add, that there are periods where it seems to post what I would say is acceptable in speed response, if I do a 'refresh' page (whether in Chrome or Firefox) it will take a perceived 200-300ms, then maybe some time later a mind boggling 1.5 mins. You can imagine trying to make multiple edits to a View setup, or Config change, I'm sitting here wondering if I should go make (another!) brew LOL
Just realised what I thought 'TOP' would be so I opened TERM and entered 'TOP'! If If put TERM in one LCD, and Firefox in other and 'reload' Firefox Drupal page I see activity in TERM, not sure to output it at the moment mind.
