FTP Compression
Bbftp tool from Gilles Farrache, IN2P3
- 10 streams & 256kByte window SLAC > Lyon got 25Mbps with NO compression
- Cpu power is important
- Sun E4500 4 cpu @ 336Mhz best could do was 13.6Mbps with 5 streams, more streams go slower
- (e.g. 10 streams =ɳ.4Mbps)
- Sun E450 4 cpu @ 450MHz 26Mbps with 10 streams
- Compression 2-3 times
- So data rate boosted to 27 – 41 Mbps (E4500) or 52 - 78 Mbps (E450)
