Update 4.4.2 is slow and causing site to go up and down, changed to 4.40.3 and seem much better

4.40.2 was not stable and slow,
Was actual waiting about 2min or longer to see pages load.

4.40.3 is way better,
I never benched marked against 4.0 that I was using prior

I'm running it on a B1 plan in Azure, it loads and runs well for with this and had it going for years.
Im about to go multi store and then I can upgrade that instead of two on B1 Plans could go P1 as you have

How is 4.40.3 (or just 4.40) doing compared to 4.2 with heavy load now?

I haven't load tested it as I've been busy with other stuff I'm afraid.

You can quite easily test yourself with https://loader.io and use their free plan.

Yeah, that's not great?! Make sure you have the timeout in the test set to 30s (normally the server default.)

This is the server - almost no load in that period.. at about 25% CPU. Memory steady

Are you using distributed cache at all?

I tried using the site while the test was ongoing now. 20s+ refresh on frontpage.. impossible to use. with only 100 clients over 1 min..

Nope. Ive tried that before using redis, but nop has never been any good at that.

Isnt nop using memory as cache on default anymore?

Yes, but just wanted to check that 'you weren't' using distributed ;)

A lot can come down to server specs mind you, but I would have thought 100 clients over 1 minute wouldn't cause an issue?!

In my tests, I was doing 150 / 200 clients per second using 4.40.1, but the server is a bit of a monster.

We are using service plans which nopcommerce should pay attention to. Its probably the future for most developers.

We are currently using this:


and a sql server with:


The sql server wasnt under load at all in the test period.
