Gents,
3rd day running XG on ESXi 6.7, and after dealing with licensing issue, let me ask another set of newbie questions:
1) XG VM is installed on SSD datastore, with 4 vCPUs and 8 GB or RAM, 4x VXMNET3 vNICs (which is recommended NIC type AFAIK). CPU never goes beyond 20%, memory (according to XG stats) 54%.
2) as soon as I increase LAN interface MTU to 9000 - XG crashes / reboots in cycle. Nothing in /var/cores, syslog before reboot only shows tons of
Mar 3 10:16:36 (none) user.err kernel: [ 357.728901] 996.769636 [ 317] vmxnet3_netmap_rxsync 155 skipped! rx_idx 256
Mar 3 10:16:36 (none) user.err kernel: [ 357.728901] 996.769636 [ 317] vmxnet3_netmap_rxsync 156 skipped! rx_idx 256
Why MTU change kills it ? And where to find crash logs, as they appear on VM screen only momentarily, I can't really capture any details
3) Performance is kind of low. Speedtest from laptop shows 100Mbps down, 80-90 up, but PPPoE line is 600Mbps. (ESXi host is good enough, even heavy-weight PANOS VM gets nearly linerate performance on it). Initial access to sites is damn slow, it looks like when I first open website - it takes like 10 seconds or more to load, but then navigation gets better. Any hints/best practices how to improve XG throughput/performance ?
BR,
Alex
