In our offices, we have a central file/print server that is fairly new, with lots of ram, that has the PST files of all our staff located on it. Our staff have fairly new computers as well. We have been experiencing lag after I created an image signature on each staff's machine. I have a lot of experience with signatures and so made the image small-ish (about 12kb) and uploaded it to our company web server (MediaTemple DV). I am wondering if the lag problem is strictly due to the web server, or could it be a combination of that with the fact that the pst file is also remote? I hope this makes sense.
