Hello, I am currently running a forum with approximately:
• 800,000 topics
• Around 12,000 daily active users
• Hosted on a dedicated server with 64GB RAM
I am considering migrating to Discourse and would like to understand:
1. At this scale, would Discourse require any special customization or architectural adjustments?
2. Is a single 64GB dedicated server generally sufficient?
Any advice or experience from similar migrations would be greatly appreciated.
Thank you！
That’s likely more than enough. How many daily pageviews do you have?
Our forum generates approximately 400,000 page views per day.
Because users have a very high search frequency, and considering there are 800,000 topics, I am wondering whether some customized search solution might be necessary.
I think that’s enough hardware. I don’t think you need to customize search. There are Discourse sites with millions of topics.
Hello,
The mentioned hardware is definitely sufficient. If you need assistance with the migration, feel free to contact me.

Depends on your disk performance. If your disk is too slow (IOPS) and your database can’t be cached in memory for most operations, it can quickly become a bottleneck.
Not really, but your specific usage pattern may discover some corner cases. At this scale, specially on the first month it’s a good idea to keep an eye for slow pages and checking if the database needs more resources, vacuum or tuning.
