Hi James.
I'm going to take a look into the perf utility. The `openssl speed`
command shows that the desktop cpu has a bigger throughput than the
laptop, so the write_partial in the desktop shouldn't spend that much
time (in comparison to laptop).
The output of the openssl command is attached.

The laptop has better specs in terms of number of threads and memory
bandwidth. I'd also have a play around with the "perf" command if all
other software versions are the same and you want to see if the lower level
CPU usage is different.

Hello James,
The CPUs are
Laptop CPU: i7 Q 720
Desktop CPU: i5 6500T
The rest of software i'm using:
Perl version: 5.22
Net::SSLeay version: 1.72
Openssl version: 1.0.2.h
OS: Archlinux up to date.
The script is single threaded and i'm using a single
IO::Select->select() to know when i shoul
Can you please give specs on both CPUs? (The exact manufacturer and model.)
Is there a reason why you think one CPU is better than another? You can
have a CPU that's old and fast at single threaded jobs (say an old
overclocked dual core 4.0Ghz CPU) and a newer CPU that's slower at single
threaded
Unfortunatelly i don't have a third box. :-(
I'm going to follow your advice and send an email to p5p.
Thank you!
Best regards,
David Santiago

The openssl version is 1.0.2.h.
Thanks for your help. I'm going to follow Uri's advice and send an
email to p5p list.
Thank you!

No, not Net::SSLeay ... OpenSSL, which it links against.
And if you recently upgraded/downgraded OpenSSL to match versions,

This is not random. This happens 100% of the times.

This snippet is from nytprof, and it's where it's spending most of the

No. My laptop doesn't have TPM (at least there's no option in the BIOS
to enable/disable and there's nothing in /sys/class/tpm/ ).
My desktop have, but not enabled:
desktop$ cat /sys/class/tpm/tpm0/device/enabled
0
desktop$
Do you think it's because of that? With other applications i can reach

Hi!
I have a script that writes to a socket, but i noticed that the same
script have diferent speeds on different machines. It's faster on my
5 year laptop than on my desktop.
I profiled the script on both machines and some functions are taking
almost the double of the time! Example:
