Hi,
I really like the class 2D scrubber in v5. However, in practice, it seems very slow to load earlier iterations - much much slower than if I just go the event log & click the specific iteration. Illustration:
Is there any way to improve this? This is just accessing on my local network, no proxies etc..
Cheers
Oli
@olibclarke Please can you post (or describe the format of) the URL in browser’s address bar when you access the CryoSPARC UI:
http: or https:?localhost, 127.*.*.* or a different host name/address?: followed by a port number?156.xxx.xxx.xxx:39000, http not https
Does the performance improve if you connect via ssh local port forwarding?
I will check thanks! Why is this expected to be better than just accessing via http? The only issue for ssh tunneling is it requires a separate setup step for each machine we want to access, as opposed to just entering the IP & port.
Avoiding the combination of (non-secure) http: and remote hosts proved to resolve some performance problems, as in Web UI won't load - #3 by ccgauvin94. Your own check will help clarify whether the delay you reported is related.
If you find that access via a loopback (127.*.*.*) address resolves the issue, an https reverse proxy, set up once for each master installation, would be an alternative to the repeated establishment of an ssh tunnel.
Hi @wtempel, I tried accessing via port forwarding (http://localhost:62222, using the command ssh -L 62222:localhost:39000 user@156.xxx.xxx.xxx). Performance is improved in some cases, but still very slow in others:
I don’t know how to set it up with HTTPS though…
Also the thing is that the performance loading checkpoints from the event log is just fine - it is at least 10x slower loading images from the dashboard, which makes me think there is another issue there apart from the connection mode.
