It's been a week now that connections to my server are slow. I can transfer one file of 6 GB at 50 MB/s but with a folder of the same size with multiple files I go down to 4 MB/s. Also, browsing a folder with multiple files takes a lot more time for the files to show. The only thing I've noticed to change since that moment is one of my drives started blinking at a different pace, it's lit when all the others are not, like it's not in sequence.
I'm kind of new with server maintenance and haven't been part of the initial setup, so I may be missing things who would be obvious to most sys admins, sorry in advance. Any help is appreciated! Thank you!

Authen::SASL::Perl::DIGEST_MD5(3) User Contributed Perl Documentation Authen::SASL::Perl::DIGEST_MD5(3)NAME
Authen::SASL::Perl::DIGEST_MD5 - Digest MD5 Authentication class
SYNOPSIS
use Authen::SASL qw(Perl);
$sasl = Authen::SASL->new(
mechanism => 'DIGEST-MD5',
callback => {
user => $user,
pass => $pass,
serv => $serv
},
);
DESCRIPTION
This method implements the client and server parts of the DIGEST-MD5 SASL algorithm, as described in RFC 2831.
CALLBACK
The callbacks used are:
client
authname
The authorization id to use after successful authentication
user
The username to be used in the response
pass
The password to be used to compute the response.
serv
The service name when authenticating to a replicated service
realm
The authentication realm when overriding the server-provided default. If not given the server-provided value is used.
The callback will be passed the list of realms that the server provided in the initial response.
server
realm
The default realm to provide to the client
getsecret(username, realm, authzid)
returns the password associated with "username" and "realm"
PROPERTIES
The properties used are:
maxbuf
The maximum buffer size for receiving cipher text
minssf
The minimum SSF value that should be provided by the SASL security layer. The default is 0
maxssf
The maximum SSF value that should be provided by the SASL security layer. The default is 2**31
externalssf
The SSF value provided by an underlying external security layer. The default is 0
ssf The actual SSF value provided by the SASL security layer after the SASL authentication phase has been completed. This value is read-
only and set by the implementation after the SASL authentication phase has been completed.
maxout
The maximum plaintext buffer size for sending data to the peer. This value is set by the implementation after the SASL authentication
phase has been completed and a SASL security layer is in effect.
