Hello... so I have also been experiencing some pretty substantial slowness in Bridge that "seemed" to get worse as the newer versions released, but has existed for what seems to be the last 3-4 versions. I'm on the current 2022 version on two systems, a xps 15 laptop with windows 11 and custom built PC with windows 10 pro. Both were seeing this horrible slowness in Bridge and it was to the point that I was researching other options. But I couldn't find anything that could do what Bridge can do with ACR and photoshop integrations, etc. I could go on and on about that road, but I'll come back to how I ended up fixing my speed issue. This post helped me to ultimatly discover what was causing my Bridge slowness. It without a doubt came down to on both systems have mapped network drives to a local server and a web server that I VPN into. Some of them aren't always connected, but still show up in windows as a disconnected drive. As soon as I removed all the mapped network drives that weren't connected, Bridge instantly performed like lightening!! It was incredible. So, my guess is that on both windows or mac, if some sort of drive is connected, but not linked... maybe even to the point of a dropbox connection, or similar, that may be causeing Bridge to crawl. Mine was litterly taking 20-30 seconds to open a directory with 1 or 2 small web sized jpgs in it. I could open a folder, click to another and clicking back into a folder would lag on loading. If I batch renamed files and clicked refresh, it would take 10, 20, sometimes even up to a minute for the files to show again. Both systems are now like lightening and I couldn't be happier. Just wanted to share my discovery and hope it helps someone else. I'm now on to seeing alternative ways to connect to other computers on the network... but for now, I'm absolutely thrilled that Bridge is fast!
