Jaap,
        I work for a stock trading firm. We are looking to have a system in place to capture the entire days worth of 
market data. We have a line that comes in and brings multiple feeds in to our servers. We would like to be able to 
let this capture run and then over-write itself the next day. The 8mb files are a nice size to work with and do not 
due much damage when moved about across wan links. So in order to get about a day's worth of traffic at 8mb clips I 
need a ring buffer of about 25000 files. The traffic adds up to about 225 to 235gb a day depending on market 
activity. The 8mb files also work very nicely in our home grown Sequence number search web app.

Can I compile Wireshark on linux to be used on windows or do I need to compile on windows?

Keep in mind that having many thousands of files in a single directory 
can be very slow on some OS/file systems.
