Very Slow Response - May 2013

Rick · May 19, 2013, 10:46:54

...and again...

Rick · May 19, 2013, 12:38:23

...this time, apparently, because a full off-site backup took a little longer than expected...

However, the fix happened pretty quickly once I'd put in the ticket.

Painfully slow again/still

7:58 - 8:09 (forum time)

Rick · Jun 11, 2013, 09:13:49

Responses taking over 30 seconds since about 08:40 BST...

Edit: Ticket submitted...

doug · Jun 11, 2013, 09:43:22

It`s 9.43 .... still very slooooooooooowwwwwwwwwwwwwwwwwwwwwww

Mike · Jul 03, 2013, 12:45:41

This morning at around 8am the website was down completely. I was getting a 101 Error for about 10 mins then gave up.

Mac · Jul 08, 2013, 17:38:00

From about 17:20 onwards today. 8/7/13

I've been getting no data returned on virtually every page,
refreshing seems to work, although a couple of pages did take a few refreshes.

Mac.

Tony G · Jul 08, 2013, 19:44:37

Likewise.....seems that it is that period when everything seems to be running slow again.

It's very useful to have a time window. It also helps to have an approximate response time / error message / symptoms.

Mac · Jul 15, 2013, 16:38:00

15/7/13 16:35 BST.

Very slow again, taking ages to get any pages.
They have not timed out.
and my connection speed is fine.

All other pages Facebook ect. working ok.

Mac.

Mike · Jul 15, 2013, 22:36:19

22:35 15/07/2013 slow response also.

Rick · Jul 16, 2013, 16:40:43

16:35 BST 16 Jul, Response times 20 to 30 seconds.

Mike · Jul 22, 2013, 10:31:50

10:33 20130722 - Website down for over 10 mins...

The connection to www.orpington-astronomy.org.uk was interrupted.

Error code: ERR_CONNECTION_RESET

Mike · Jul 31, 2013, 12:12:38

Incredibly slow all morning. Typically 30+ seconds for any clicked link to do anything.

Surely enough is enough Rick? We are paying for a service we are just not getting. Can we not simply move servers?

Les R · Jul 31, 2013, 12:49:28

Ah.... Not just me then! I did think it might have been my mobile dongle, but other sites seemed to be ok.

Migration to a different server shouldn't be too difficult once the MySQL has been setup and template installed should just be a case of exporting and importing once done. No harm in experimenting on a server to check, though I'm unsure how the domain settings would work until the DNS entries were changed. SMF should be able to advise and the process.

Rick · Jul 31, 2013, 13:24:02

It was a little sluggish earlier, but seems fine at the moment, which makes troubleshooting tricky. I have an open ticket to hit next time I catch it being slow.

Exact times, response times and error messages (with exact times) are helpful.

Migration involves:

Transferring all the files
Transferring the mailing lists
Transferring the databases
Transferring the domains and getting the DNS re-configured
...and so on.

It can be done, and if things get much worse I'll consider it, but last time we shifted servers it took a while to sort out, and I'd rather not put effort into that until I'm certain our current provider isn't prepared to respond. There's quite a few months already paid for, too.

They should be giving us a refund for failure to provide the service.

Rick, I realise it would be a bit of work, but i don't think it would be as bad as you think. You certainly WONT need to transfer the domain and the DNS protocols takes seconds to point to your new web host nameservers. Files are a simple FTP job, not sure on the mail lists, but would imagine that shouldn't be a problem though the database export and import so it matches what you currently use, will be the only real headache in the process.

Hopefully they pull their finger out, but if you decide to do something, I'm happy to help if any is needed.

Rick · Jul 31, 2013, 16:05:07

Most of the time the sites work fine. Occasionally they're a bit sluggish. While the sites were a bit sluggish this morning, I was able to upload the monthly presentation and do other stuff, so they weren't actually unusable from my point of view. I have reported the sluggish responses, and the hosting company is going to try changing some things at their end to see whether it improves matters.

Having a record of specific time windows when the sites are sluggish or unusable would be useful.

I did the transfer work last time we moved servers, so I know what's involved. The set-up now is slightly more complicated than it was last time, but I'd have more time to work on it. However, I'd much rather the hosting company found and fixed whatever's causing the trouble. I suspect it's database-related and probably caused by other customers databases on the same shared server, but I'm not ruling out the possibility that it's down to our forum database having almost trippled in size in the last four years...

Mike · Jul 31, 2013, 16:18:30

It's a bit more than 'sluggish' Rick. For example just now I clicked the REPLY button to reply to this post and it took over 20 seconds. It's almost unusable at times and quite regularly I get the 'Error code: ERR_CONNECTION_RESET' message.

Rick · Jul 31, 2013, 16:43:41

I'm clearly not seeing the same level of poor performance as you're seeing, then, Mike. I've seen a few occasions today when responses took over 30 seconds, but no cases of connection resets or other such failures.

Rick · Jul 31, 2013, 17:11:11

The hosting folks report that they are working on reducing the load on the server hosting our sites.

Mac · Jul 31, 2013, 17:50:38

Quotebut I'm not ruling out the possibility that it's down to our forum database having almost trippled in size in the last four years...

How big is our database then, it can be that big.

maybe we should spolit the forum into two
one that holds everything for the current year
and one that holds everything else, and on the 1st of Jan
archive everything from the previous year.

Its not that hard to build SQL queries to access the old database,
so at least you can still search.

On another note, it says at the bottom we are on 1.1.18 of the forum software
the current version is 2.0.4. is it worth looking into the upgrade?
it might be a combination of bug fixes and server issues.

Mac.

Rick · Jul 31, 2013, 18:39:43

We're on a shared server, so the chances are high that poor performance is caused by something else. The database may have trippled in size but server performance should also have increased. I'll only consider doing stuff like that to the database if it's identified as the prime cause of a performance problem.

The update from 1.x to 2.x is something on the list, but the bulk of the changes are of the "greater flexibility and complexity" variety, and, barring intermittent poor performance (which is probably server-load related), this version works well enough.

Painfully slow at 07:29 (forum time) took over a minute to post a reply

Rick · Aug 13, 2013, 09:30:51

Yes, things have been a bit sluggish at intervals this morning. I'm watching it fairly closely. Some of the load may be down to bots crawling all through the new version of the main site...

Taking ages to get any pages up,
they have not timed out yet, just slow.

Mac · Aug 24, 2013, 10:29:24

This is getting stupid now.
It took over a min to post one reply.

At what point are we going to change servers?

are we paying a lower rate for a crap service?
because that's what we are getting.

10:28

Mac.

Les R · Aug 24, 2013, 10:49:16

very slow here also.

As a side note - not sure which domain host / site host you are using, but do you have a option to action things when the domain includes www as an input or not?

ie

http://orpington-astronomy.org.uk/ gets you through to the root dir and things I guess you might not want to be seen. (I haven't looked honest!)

whereas

http://www.orpington-astronomy.org.uk/ correctly brings up the site index page.

I guess as no page name is shown, you are using frames? (which is not the best way, and might attribute some of the sluggishness here.)

On a host I use, you can set to direct any input (ie www or not) to wherever its meant to go. Using frames youve got one option. Much better to change the nameservers and make this all transparent. (Though I am just making assumptions here, so apologies if thats not right!)

Rick · Aug 24, 2013, 10:52:29

Thanks, Les. That should not be happening.

I hope I've fixed it. I hope I've not broken anything else along the way...

Trouble with the performance issues is that they are intermittent and usually short-lived. If I can get a ticket in when the site is actually runninng slowly then it usually gets fixed promptly.

No problem. I was going to mention it before. (Its always done it, so nothing to do with the facelift.)

mickw · Sep 04, 2013, 10:46:00

Crap again 9:21 (forum time) - 30 secs+ to refresh or link

Rick · Sep 04, 2013, 12:16:17

Any idea when it started responding again? Pin down the time the slowness stops, and that might give them a hint what's causing it...

mickw · Sep 04, 2013, 12:20:04

Possibly around 9:45

Rick · Sep 05, 2013, 10:43:44

Thanks. Pattern's repeating today. Another ticket entered...

Rick · Sep 05, 2013, 10:49:03

...and got a reply before I'd finished submitting that last post to say they were working on it, so hopefully...
