don't do that. If you just need a compression on such a high throughput connection, just use gzip. If throughput is the limiting factor, not CPU, use xz. Also you should be able to do between 100MB/s to 1GB/s on 10 GE, which is nowhere near 8h. (Unless you use SSH which does encryption which will slow you down massively. "-c arcfour" can help, but in these ranges probably not much as the encryption will not use multiple threads.)
