Great and satisfying answer Garret, thanks so much. The original main network card is a bge. The two rge were added to implement the connection to the XStream Storage. Do you think that two bge would have been better? Gabriele. Da: Garrett D'Amore A: [email protected] Data: 28 marzo 2013 15.19.13 CET Oggetto: Re: [discuss] rge driver slower? SunFire sparc systems have lower single CPU performance, and higher overheads for DMA setup &teardown. There are probably some extra costs for endian swapping descriptor rings as well. (Although it is possible to establish mappings that do this in hardware. I'm not sure if rge does this though. Additionally, the rge driver has never been optimized for use on SPARC. Frankly, I don't think anyone ever thought there was much need, I've not actually heard before of any body using rge on SPARC in production. - Garrett On Mar 28, 2013, at 6:27 AM, Gabriele Bulfon [email protected] wrote: Hi, I understand this is a Solaris 10 issue, on a native SunFire sparc machine, but maybe someone knows, and it's against an illumos based XStream Storage machine ;) I tested throughput using netio between some VMware XStreamOS and Windows machines, and an illumos based XStream Storage server. Both results in almost 110KB/s. Doing the same on a native SunFires sparc machine using rge devices, having max 80-90KB/s. Any reason?
