TZ 270 - 7.0.1-R1262 - bad experience with low bandwidth connections

BWCBWC Cybersecurity Overlord ✭✭✭


one of my customers got a new TZ 270, because it's a very small location with very less bandwidth (1.5 Mbps). In the past with Gen6 that was no major issue, it was slow, but I was able to connect to the Firewall without any bigger problems.

But with the new inflated SonicOS 7 it's close to a nightmare. It took around 2.5 minutes from connecting until it showed the Dashboard. It loaded nearly 30 MB of Data.

Assuming all these files are really needed and optimized, why not honoring the "Accept-Encoding: gzip, deflate, br" Request Header the Browser is providing and gzipping these huge files? This would bring down the marked 19MB to around 5MB, a 75% reduction in data transfer?

On-Box Management in low-bandwidth environments will be a real struggle.

    Yeah, would be good if there was a low-bandwidth optimised version or theme for the web interface. I would be happy to accept fewer features/graphics/colours/whatever in the web interface, in exchange for the ability to get things done more quickly.

    Compare the speed of the Gen 4 web interface with Gen 6 and Gen 7. It's not just Sonicwall guilty of this, I get the feeling that web interface developers only test things on a fast, recent PC with a 1G link to whatever it is they're developing!

    Hi @Arkwright having a different theme will probably not happen, I'am still annoyed about the Classic/Contemporary Situation on the SMA. But by just gzipping the content coming from the Firewall it would help a lot, performance overhead is IMHO minimal considering the new Appliances are so powerful (according to SNWL).

    I can confirm poor performance of the managment UI in a low internet bandwidth environment. Even when managing locally. TZ570 on 7.0.0 R9XX.

    I do wonder, if the firewall has internet it will try to pull things from Sonicwall's servers. Cause when managing locally without internet there aren't any delays.

    It's not just bandwidth, unfortunately. /api/sonicos/dynamic-file/getObjectList.json [~430KB] is fetched every 11-15 seconds so long as you have the web interface open, even if you're doing nothing with the web interface. This pegs a core for about 3-4s on my machine, every time.
