How can I increase the rate limits of the firewall rules?

[girish]

@vova Let me double check but Cloudron has no rate limits for outbound connections. Only for incoming connections. If it's interesting, the full firewall and rate limits are here - https://git.cloudron.io/cloudron/box/-/blob/master/setup/start/cloudron-firewall.sh

@vova Also, maybe you can just upload a random large file from one server to another via scp or something. That would be a good way to check if it's a Cloudron issue or some general networking issue.

Only for incoming connections

Thank you. The connections are incoming, I think. We send packets from server 1 to server 2 (server 2 is where Cloudron is). The packets are product data like updated prices, discounts, quantities (100 products per packet), and the packet is 40-50kb, the total number of products is ~4100.

@vova So, it's coming to a Cloudron app (if so which app is this?) or some program you have installed external to Cloudron? If it's related to cloudron firewall, you will see a log message in dmesg (https://git.cloudron.io/cloudron/box/-/blob/master/setup/start/cloudron-firewall.sh#L55). There will be a "IPTables RateLimit" log message. Do you see something like that?

@girish It is a Cloudron app - Wordpress unmanaged. I will check the log message.

Hello, I had to replay from this profile (in my office) as I forgot which email I have used for the other profile at home

Anyway, please find the log below - I can't exactly see IPTables RateLimit, but I see some drops which maybe are some limits also? This log is when we try to send 100 product data per batch - it gives an error at 100-200. When we send 50 products data per batch it is okay but kinda slow.

@Vladimir Quick question: so if you upload something from the server to your main destination (any random data), is it fast? How about if you upload the same data via the Web Terminal of the app?

[Vladimir]

@girish Since yesterday we can't even send 50 products per batch (which is 30-40kb) without an error - it is super slow and there is a timeout error. We have tried to send very small data (the data for only 1 product, which is under 0,7kb) and there was an error again.

@Vladimir Can you send me a mail on support@cloudron.io? Let's try to figure where it's failing.

[Vladimir]

@girish I have send an email (v.evtimov.beta). Thanks!

@Vladimir Got the mail, will follow up there. Thanks.

Follow up from the customer: "The issue here turned out to be that in Wordpress, WP Rocket caching plugin was used. This plugin automatically starts to preload the cache of each page once something in the site has been updated. The preload itself causes some stress on the CPU and maybe some other processes. Turning off the plugin, the products were sent for less than 2 mins."

They are working with the WP Rocket team to find a workaround.
