Minimal Resource Requirements + load handling for agents

[MehulG]

We are trying to get a better understanding of how agents function on a low level.

• What is the minimal resource requirement for running an agent? This would be helpful for testing and resource management purposes, especially in environments with constrained resources and large number of agents.
• How many concurrent requests can a Fetch agent manage during peak load times?

HI @jrriehl / @lrahmani,
Can you please look into this?

@MehulG I asked the same question on end of august:

I have checked the Memory usages of a basic agent code using memory profiler package:
https://pypi.org/project/memory-profiler/

from memory_profiler import profile

@profile
def load_uagents():
    from uagents import Agent, Context

if __name__ == "__main__":
    load_uagents()

Output:

Line #    Mem usage    Increment  Occurrences   Line Contents
=============================================================
     3     22.9 MiB     22.9 MiB           1   @profile
     4                                         def load_uagents():
     5     74.4 MiB     51.5 MiB           1       from uagents import Agent, Context

I also checked with psutil:
https://pypi.org/project/psutil/

import psutil
from memory_profiler import profile
from uagents import Agent, Context

agent = Agent(name="alice")

@profile
@agent.on_event("startup")
async def introduce_agent(ctx: Context):
    process = psutil.Process()
    ctx.logger.info(f"Hello, I'm agent {agent.name} and my address is {agent.address}.")
    ctx.logger.info(f"Memory Usage: {process.memory_info().rss / (1024 * 1024):.2f} MB")

@profile
@agent.on_interval(period=2.0)
async def say_hello(ctx: Context):
    ctx.logger.info("Hello!")

if __name__ == "__main__":
    agent.run()

Output:
INFO: [alice]: Memory Usage: 73.45 MB

TLDR; I did a memory usage check for the basic uAgents code using both the memory-profiler and psutil packages.
Here are the results:

Using memory-profiler:
When importing Agent and Context from uagents, the memory usage jumped from 22.9 MiB to 74.4 MiB, showing an increase of about 51.5 MiB.

Using psutil:
When running the agent with basic event handlers, the memory usage was recorded at 73.45 MB.

This suggests that initializing and running a simple uAgent requires roughly 73-75 MB of memory in the current setup.
