I know this can help alot w/ ssh on plain text and the like but I was
wondering specifically about CIPE. Could this be implemented inthe packet
encapsulation and would we see a performance increase accross low
bandwidth lines. My guess is that it would; I just took a block of
[root@dev dev]# dd if=/var/log/messages bs=1400 count=1 | gzip -v9 | wc -c
1+0 records in
1+0 records out
You can see that even for mall 1400 byte packets we can get a 77% size
cut. Would it be feasible to implement this into CIPE?
