Description Matt Domsch 2001-10-03 14:59:02 UTC

Description of Problem:
With Linux 7.1 installed on a PowerEdge 7150 system and 32-client stress 
test, the text console mouse response is very slow.  The response to a 
command prompt is good.  Also the performance of the processors when 
running top is CPU0 99.8 % and CPU1 60 %.
Client connectivity is good; stress test from the 32 clients is running at 
just about 2 days. 

7.2 RC1 seems to have the same problem.

Config:

BIOS X18/frmwr x15
2x800Mhz/2M
32x128MB (4 GB)
slot3 Ql2200 Moon/Haley (4 Hard Drive RAID0) OS installed.
slot4 Pro100+
slot5 Pro100+
slot6 Pro 100+ DP
slot7 Pro 100+
slot8 Ql2200
slot9 Ql2200
slot10 Ql2200



Version-Release number of selected component (if applicable):
RC1 (2.4.7-2 I think)

How Reproducible:

Steps to Reproduce:
1. see above

Additional Information:
Dell TeamTrack #DFCT39801, sev 2.

Comment 1 Michael K. Johnson 2001-10-04 18:59:47 UTC

Text console mouse is done through a process (gpm) that is competing for
CPU time with everything else the system is doing.  I do not think this
is a bug.
