[j-nsp] Updating SRX300, now slower than before

[Markus]

Hi list,

I'm moving a couple SRX300 that were running 15.1X49-D90.7 to a new 
purpose and just updated them to 21.3R1.9 to be a bit more up-to-date 
and now booting takes twice the time (5 mins?) and CLI input also seems 
"lag-ish" sometimes. Did I just do a big mistake? If routing/IPsec is 
unimpacted then it's OK, or could it be that the SRX300 will now perform 
slower than before in terms of routing packets/IPsec 
performance/throughput? Or is that stupid of me to think? :)

Thank you!

Regards
Markus
