Why it is so slow to load Lazarus Forum Web?
« on: November 26, 2021, 05:58:48 am »
Hi guys,

It took about 15 seconds to load this forum website.
Tried on PC and mobile, phone, same respond, slow.
Why is it?

Problem is not from my internet, cause to load others web, it only takes less than a second.

Hi!

Yes it is strange:

Since some days there are sometimes awful response times.

But 10 minutes later all works normal. And then again: waiting ...

Are there attacks to the web-server?

Yesterday (25th) was particularly slow, today seems better. I was keeping a particular eye on this and comparing it with responses from eBay etc. in case it indicated a network problem at this end which could affect business telecoms etc.

The fact that multiple people notice this suggests that it's at the server end, or near the server end's routing.

26th 09:20: Response moderately slow again.

Page load times downunder vary between 15s and 45s depending on the time of day, with some days being worse than others. Tonight it's better at 6s to load a page. The mornings are generally worse (UTC+10).

Yesterday afternoon was /particularly/ bad.

GMT here and proud of it: we invented this stuff.

There is some new webcrawler. You can also see that there are 8 registered users online and 344 guests.

Some occasional slowliness is also possible if people heavily use the search feature.

One thing we found out is that I might be caused by the way mysql does database locking. It might block other requests. One thing I plan to do when I find some time is to move the database form mysql to postgresql (since it is sopported by smf nowadays)

Probably a good move. Postgres has served me faithfully for 20 years.

It seems to be very capricious.  Sometimes the response is immediate, other times it's immediate after a wait of 20 to 30 secs.
(FPC v3.0.4 and Lazarus 1.8.2) or (FPC v3.2.2 and Lazarus v3.2) on Windows 7 SP1 64bit.

Agreed, I'm not seeing any real problem ATM despite the number of guests being 200+

It's obviously possible that the forum server is throttling traffic to a subnet hosting an implausible number of guests, but I'd be surprised if a crawler/spider were sufficiently synchronised to be coming from one direction at a time.
