I noticed at LLO (?) that the LSC screen there uses up ~25-30% of the CPU time on a single core for the control room iMac workstations - this seems excessive.
Here is an accounting of CPU usage percentages for some of our screens:
Screen Name |
CPU (%) |
LSC_OVERVIEW |
7 |
ALS_OVERVIEW |
0 |
ALS |
1 |
SUS_SUMMARY |
0 |
IOO_WFS_MASTER |
0.3 |
OPLEV_MASTER |
0.5 |
These were measured using the program 'glances' on rosalba. MEDM running with only the sitemap used up 0.9% of a CPU. With the screens running, the fluctuation from sample to sample could be ~ +/- 0.5%. While the LSC screen seems to be the biggest pig, it is only big in comparison to small pigs. Certainly this pig has gotten bigger after getting sent to Louisiana. |
