Very Slow - or Non-Existent - Performance for a qlcnic with Solaris 11
(Doc ID 2511950.1)
Last updated on SEPTEMBER 09, 2019
Applies to:Solaris Operating System - Version 11 11/11 to 11.3 [Release 11.0]
Information in this document applies to any platform.
Extremely slow performance - with NFS READS, and other incoming data flows - when using a qlcnic device.
Packet captures reveal the external sender is re-transmitting TCP packets at a very high rate.
Meanwhile, the receiving Solaris host is recording tcpInErrs per netstat -s , and ip:0:ip:inErrs per kstat data (these both record the same thing) - indicating invalid TCP packets are being received.
The qlcnic statistics however indicate no issues - no packet quality (checksum or frame length) issues.
