Slow speeds on accessing File Server (via Samba from Windows 7) specifically due to JPEGs (thumbnails)
Using latest TKL File Server version (I think-- which is using Ubuntu 10.04.1 and Webmin 1.560 and Samba 3.4.7). I have problems with people using Samba (using Windows 7) over FTPS-not local to the network (using Expandrive http://www.expandrive.com/ ) getting very slow performance in accessing folders. These are folders with large numbers of jpegs and because of the application, the people are using their File Explorer with the View Thumbnails options (to see the various JPEGs for inclusion in webpages). They take awhile for the files to come up. I've enabled the read prediction (in the Samba misc options), but is there anything to do to make this work faster?
Is there some Linux program or process I can have running on the server which will prepopulate (certain) folders with thumbnails for the JPEGs contained within so the folders will present themselves faster?
Is this simply a bandwidth problem or a local computer processing problem (look for better cache options on the local machines)? Or might this be a problem with something going on the Expandrive FTPS?
Any advice would be appreciated. If anyone needs any other info required from me to get this to work better, let me know and I will get you the info ASAP.
