Does SOLR use up a lot of memory on a server?

[Martinplacemen]

I have no experience with SOLR.Does SOLR use more memory on a server than, say, MySQL?I am about to purchase a VPS-package, but they come in different sizes, as you can imagine...I contacted the providers today by email, and told them that I was planning on using SOLR, which requires a Java installation. Their response was that it would work fine, but that I should go with a more expensive VPS package than I was initially going to order, because "Java applets require a lot of memory".Here are the two packages they provide. I was initially going to order the standard package:STANDARD Package:

• Processor cores: 1
• RAM: 512 MB
• Guaranteed RAM: 256 MB
• Disk System: RAID5/50
• Price: $20 / Month

GOLD Package:

• Processor cores: 8
• RAM: 2048 MB
• Guaranteed RAM: 1024 MB
• Disk system: RAID10
• Price: $50 / Month

I have about 25,000 records in a MySQL table, each of which has about 10 fields. The site is PHP-based. No heavy stuff at all, actually!I have never had any VPS before, so any guidance is appreciated! Which do you think I should order?If you need more info, please let me know!
