What is the effect of the set cmp parameter -cmpBypassPct 70 when compression is enabled on the NetScaler?

• A. Compression will be bypassed if the NetScaler bandwidth consumption is more than 70%.
• B. Compression will be bypassed if the NetScaler Memory utilization is 70%.
• C. Compression will be bypassed if the NetScaler CPU load is 70%.
• D. Compression will be bypassed if the NetScaler bandwidth consumption is less than 70%.

Answer: (C)

This parameter sets a CPU utilization threshold for bypassing compression. NetScaler’s compression uses CPU time to shrink responses, so the bypass threshold prevents the compression task from consuming too much CPU. With -cmpBypassPct 70, compression will be bypassed once CPU utilization reaches about 70% (and will resume once CPU availability drops below that level). This protects overall performance by prioritizing CPU headroom over continuing compression. It’s not tied to bandwidth or memory usage, which is why the other options don’t fit.
