Slow switching tabs

2026-03-26 13:11

Hi, it may or may not be an issue on my end, in the past WinSCP understandably took a while opening/switching to folders with huge number of files, but recently I started having issue with switching to tabs that contain just a few files and therefore should load pretty much instantly, but it sometimes takes several seconds.
I don't know to fix this or what specific info to provide. These are SFTP sites, my PC is Windows 11, 64GB RAM, NVMe drive ... let me know what more info to provide

I tried Debug2 level log, the only thing it contains pretty much is:

. 2026-03-26 13:09:16.630 Session upkeep
. 2026-03-26 13:09:16.630 Looking for network events
. 2026-03-26 13:09:16.630 Timeout waiting for network events
. 2026-03-26 13:09:17.130 Session upkeep
. 2026-03-26 13:09:17.130 Looking for network events
. 2026-03-26 13:09:17.130 Timeout waiting for network events

and not sure it's relevant ... logs for all tabs contain the same log data, but I was switching tabs at different times

Thank you!

Thanks for your report.

Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include a link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

You will find my address (if you log in) in my forum profile.
