List-Unsubscribe: , List-Archive: Hello to everybody. we are reporting a very low performance for nfs access from Solaris clients to the linux nfs server on RH8.0. We thought it was udp and upgraded to kernel 2.4.20. Now the performance is still low, compared to a solaris server: # time gtar xf /var/tmp/cvs-1.11.5.tar Writing on Linux_2.4.20> real 0m22.132s Writing on Solaris_8> real 0m7.174s Both filesystems are mounted with proto=tcp,rsize=32768,wsize=32768. Snooping the traffic however, it appears that the linux server is not serving with size=32768, but with a maximum size of 8192. - Is there a reson for this? - May this be the reason for the poor performance above?
