I have been continuing to use Hiawatha on the file repository. I wanted to move a huge amount of data from the main server to a backup server. This is what I did:
- Enabled NFS server on the main server
- Exported the /var/www/html (webroot) as a shared folder
- Ran NFS client from the backup server
- Started copying from the NFS share to another folder on the backup server
When doing "TOP" on the main server, I notice that the CPU usage of Hiawatha went way up - almost at 100%.
I wanted to compare it with Apache. Started apache instead of Hiawatha and did the same thing as I did above. The CPU usage and memory of Apache does not show up as high in "TOP". But looking at "ps auxf", I found that Apache had started 32 instances of itself.
This is not a bug report. Just an observation of what I found. Not sure how NFS impacts the HTTP server. Maybe because they are using the same folder.
BTW, do you have any suggestions/ideas on how to copy large amounts of data between these VM's - in a fast/multithreaded way? I know .. this is outside Hiawatha.
Hiawatha version: 6.15
Operating System: CentOS 5
