Noticable delay before the window showed up #809
Comments
Hey @yvvki thank you for the issue! Which backend are you using on Rio? Is the automatic? If yes, I wonder if using Vulkan would speed up |
Indeed that switching to Vulkan speed up my system on idle. I use this cute script to help me test the startup time. import subprocess
import time
def measure_execution_time(command, iterations):
total_time_ns = 0 # Total time in nanoseconds
for _ in range(iterations):
# Record start time
start_time = time.perf_counter_ns()
# Execute the command
subprocess.run(command, shell=True, stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL)
# Record end time
end_time = time.perf_counter_ns()
# Calculate elapsed time
elapsed_time_ns = end_time - start_time
total_time_ns += elapsed_time_ns
# Calculate average time in milliseconds
average_time_ms = total_time_ns / iterations / 1_000_000
return average_time_ms
# Parameters
iterations = 25
command = "rio -e echo READY"
# Measure and print the average execution time
average_time = measure_execution_time(command, iterations)
print(f"Average execution time over {iterations} runs: {average_time:.2f} ms") I am running on Linux 6.12.0 Zen kernel with 11th Gen Intel i5-1135G7 and this is the result in my machine:
I run the script after rebooting, immediately when my graphical session starts and change the print with this: # Write the results to a file
with open("/tmp/rio-result.txt", "w+") as f:
f.write(f"Average execution time over {iterations} runs: {average_time:.2f} ms\n") This is the result with just 1 iteration:
Though using Vulkan helps, it still have that 3 second delay in my end. |
I have a quite fast NVMe drive and planning to use Rio daily. But unfortunately every time I boot and login to my graphical session, I had a quite annoying delay opening Rio before I can use the terminal.
The other terminal emulator that I have tested include Foot and kitty. While I have no number to compare it against, my personal experience tells me that Foot goes the fastest, Rio is the slowest, while kitty is somewhere in between.
But the actual reason of why I create this issue is that every time I use Rio just after booting, it sometimes have delay of over 2 seconds before showing up the window.
Is there a way to improve Rio start-up time, especially after booting up?
