Hi,

It looks to me that the response-times when replying or adding new topics increased.
This results in people reposting the same form over and over, causing duplicate posts.

Hi Frank,

We are busy investigating the problem. Would you mind posting the following to help diagnose the problem:

1) "Total time taken to generate the page:" (see bottom of page):
2) Actual time taken:
3) Time of day:

Best regards.

Really bad again - right now. Pressed 'Submit Reply', 1 minute later pressed 'preview Message' which returned in 10 seconds, but now had two copies of the reply in the thread.

How do you want us to record and post the various details of this problem.

David

Upd: This posted in just a few seconds but the 'timer' said 0.26nnn seconds. Can we put a timer further 'out' so that it starts earlier in the process?

Upd 2: The first update took "Total time taken to generate the page: 0.25771 seconds" but subjectively was way, way quicker that the original post which 'took' nearly exactly the same time to generate'.

Help is on the way. We will be able to upgrade the main server soon. More details later...

Hi,

Good news: we've got a bigger server and will migrate everything to it over the weekend.

Best regards.

Any downtime planned? Perhaps we could announce it in the most popular forums.

Definitely a good idea!

The site will remain available most of the time. However, downtime can be expected from Saturday morning, possibly even on Sunday.

New server's details:

CPU: AMD Athlon64 3000+, 384K Cache
RAM: 2 GB DDR-RAM
Hard Drive: 2 x 160 GB / 7200 RPM in a RAID 1 configuration (mirrored)
OS: CentOS Enterprise Linux

Best regards.

We would like to switch off the old server. If there is anything that is still not working/ not copied across, speak now or forever hold your piece.

Accented characters came across incorrectly. In the sticky for the 'SQL & PL/SQL Newbies' forum there is the following:
Quote:

A large group of the questions posted here are just a déjà -répondu of the past.
I fixed it in the sticky for the 'Forms' forum by copying from a text version I have saved on my PC. I don't know how many others there may be in the 'posts' database.

Concerning incorrectly accented characters, I also saw this on a 'new' post http://www.orafaq.com/forum/t/58275/67467/ (at the bottom).

Problem fixed. However, users who recently fixed their posts will have to do so again.

Is the server having problems or is it my organisation's internet connection? Because responses are really slow for me this 'morning' (my time).

Everything looks OK. The server is busy at times, but on average it is coping quite well:

-bash-3.00$ uptime
 23:20:40 up 43 days,  8:49,  1 user,  load average: 0.32, 0.88, 1.70

"Total time taken to generate the page: 1.97488 seconds" I think it is a bit slower ... normally the generate time is in milliseconds.

David

But added this post was "Total time taken to generate the page: 0.02167 seconds" and doing the edit page was "Total time taken to generate the page: 0.09008 seconds"

And the update was "Total time taken to generate the page: 0.63859 seconds"

This server is serving +- 700,000 pages every day. The occasional 1 or 2 second delay is to be expected.

One or two seconds is very acceptable, it was the 20 to 65 seconds that were becoming annoying. I have a feeling that it may have been my work place's internet connection. Have we ever had a 1 million page day?

Not yet - I don't think the current hardware can handle such load!

It's bad luck if you ask me. I've never seen it that slow. That said, I guess it may happen from time to time depending on the server's load.
