Hello, I'm trying to conduct an experiment wherein I measure file-caching performances over wireless connections. My basic setup includes one client and two servers. In a nutshell, what the experiment does is to make the client copy a fixed number of random files from a file pool found in both servers. The client then caches the files it copies, so the next time it tries to copy the exact file, it simply reads off the cache.
Since I implemented my own caching mechanism, I'd like to now decide on how the network file transfers are to be made. I initially thought scp would be sufficient, but I'd like to ask the mailing list's opinion on using NFS. The problem with NFS however, is that it seems like it already has it's own caching procedures (which in turn, may screw my test results just like Coda did). I heard of the ability to "disable nfs caching" from browsing the net. However, I'm not sure of what this does exactly and whether it is sufficient (there may be other caching procedures and NFS-related factors that may affect my test procedure, not necessarily file-caching). I plan to do more research on this, but I would highly appreciate any additional insights. Thank you for your time. -Paul Patrick Carpio Prantilla University of the Philippines ======================================================================== BTW, for those of you interested in what the point of the experiment is: Everytime a file is cached, a priority value is assigned to the cached object. This value derived from the wifi connection strength between client and server, size of the file, and the number of times the file has been accessed in the past. The objective of my experiment is to discover the optimal weights that should be assigned to these factors in a wireless environment. -- Philippine Linux Users' Group (PLUG) Mailing List [EMAIL PROTECTED] (#PLUG @ irc.free.net.ph) Official Website: http://plug.linux.org.ph Searchable Archives: http://marc.free.net.ph .
