Problem: Our server becomes very very slow (near freezing) if I copy a file from any directory on C: and D: to any other directory. In short It becomes very slow if I touch the hard disk. Currently I have turned Oracle off (It's not our main database) and things are working but very unstable and I can not touch anything.
What I have found:
What we have there: Windows 2003 R2 Enterprise x64 SP2 (Uptodate), Oracle 11g (Currently all of it's services are down; so it is not actually working; but before this, it was being updated by our main server via Oracle Streams), ~10 .NET applications (3 of them make big log files ~5 GB/day) and 20 ASP.NET websites and services, 2 of out applications talk using MSMQ (which is very important to us and it's performance drops to 10 messages/sec when we where passing near 100 messages/sec before) we process near 3,000,000 messages/day.
Applications (and their logs) are on D:, Oracle data is on E:.
- C: Total Size 44 GB, 12.5 GB free
- D: Total Size 295 GB, 35.5 GB free
- E: Total Size 1.36 TB, 282 GB free
- Intel Xeon XPU 2.00 GH, 4 cores,
- 48 GB RAM,
- 6 * Fujitsu MAX3073RC 73GB 15000 RPM 16MB Cache Serial Attached SCSI (SAS) RAID 5 (C: & D:),
- 2 * Seagate Barracuda 7200 1.5 TB 7200RPM SATA 3Gb/s 32MB Cache RAID 1 (E:)
Our admin is unreachable until next week; and I am not the admin :\
